Appearance and structure Significance of Control cable

The appearance of the product quality is very important, usually the first impression to the user is the appearance of the product quality, therefore, all good product pay great attention to appearance quality, the appearance quality, production workers and inspectors can not be ignored, we will strictly control to ensure appearance quality.

Check the appearance and structure size of the cable generally is carried out by or at the same time, the quality of products on the one hand, to see if the performance is good, but the quality of its appearance, structure size also account for certain proportion, the appearance and structure size of the product has an impact on the performance of the cable.

The appearance of the control cable inspection is to check the surface of the finished products, semi-finished products or materials, and the dimensional check is stipulated in the product standard of each size to review each product. The cable structure inspection refers to the structure of each component are inspected, appearance inspection problems such as the oxidation of copper wire has an impact on cable quality, size can be a direct impact on the performance of products, such as the diameter of a conductor and its resistance; Insulation thickness and resistance is related to degree of pressure; The winding pitch and product flexibility, strong degree. Check can reveal the manufacturing quality of the cable structure, find the problems existing in the production process, so control the appearance and structure size is the assurance of product performance.

Applications of Armoured Cables

When all kinds of plastic wire and cable laying, they will suffer various external mechanical forces, such as bending, stretching, twisting, positive pressure, impact and vibration, etc. All of the external mechanical forces exerted on the cable will cause a certain of damage to the cable. In order to protect the cable structure and electrical properties, and improve the service life of the cable, it is very necessary to add armoured layer to the cable outer sheath.

There are usually two kinds armoring layers of Cables, steel tape armoured and steel wire armoured. In order to make the cable can withstand radial pressure, we adopt double steel belt, gap around the package process, known as the steel tape armoured cable, wrapped steel strap on the cable conductor after cabling, then extrusion plastic sheath. The representation method of this kind of cable model number is such as control cables KVV22, plastic power cable VV22, communication cable SYV22, etc. The cable mainly used in big occasions of bearing pressure, such as crossing the road, square and vibration of road, railway and etc., suitable for buried, tunnel, and wear the pipe laying. In order to make the cable withstand larger axial tension, we adopt low carbon steel wire by winding process, known as the steel wire armoured cable. Wrapped steel wire according to certain pitch circle after cabling, then squeeze sheathed on the conductor. The cable is generally used occasions with large span and bigger laying gap.

Anytekabel Co.,Ltd. in Changzhou, China, further improve the armoured cable manufacturing, to make it bear external mechanical forces as much as it can. Mechanical protective layer of Armoured cable can be added to cables of any structure, in order to increase the mechanical strength of the cable, improve the ability of anti erosion, design for prone to mechanical damage and easy to erosion area. More generally, armoured cable is buried power cable, transmiss power by power line.

10. if cable cannot timely storage for some reason, should put it in a dry place, prevent sunlight insolate and cable end into water etc.

Difference between the power cable and control cable

Power cable in the trunk power system for electricity transmission and distribution functions, control cable from the power system of power distribution point to transmit electricity directly to various power connections of electrical equipment. Power cable of rated voltage up to and including 0.6/1 kv of above commonly, control cable is mainly for the 450/750v. The same specifications of the power cables and control cables in production, power cable insulation and sheath thickness thicker than the control cable.

Control cable belong to electrical equipment with cable, and power cable is a cable two of five categories. Standards of control cable is 9330, power cable GB12706 is the standard. The color of the control cable insulation wire core is usually white, black and low are generally color separation power cable.
Control cable cross section is generally not more than 10 square, power cable is mainly the power of that are generally large cross section. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet, again big cross section, can do manufacturers is relatively less, and control the cross section of the flexible cable generally smaller, generally no more than 10 largest square. Some conclusions from the cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user requirements.

Technology development trend of fire retardant cable

With the increasingly popular of the information systems, it begins to enter all kinds of working environment and household, integrated wiring system has shifted from a new invention of twenty years ago to help people in daily life can be seen everywhere in the information system transmission cables. When people are able to complete high stability, high reliable integrated wiring system, whether the wiring system can resist external invasion and avoid harm becomes the new target of attention abroad.

The development trend of fire retardant cable
At present, the integrated wiring manufacturer has already entered the sales way of globalization, the integrated wiring manufacturer both have High flame retardant cable and low smoke zero halogen cable wire these two big series, and some manufacturers have already meet the requirements of low smoke zero halogen, and satisfies the requirement of high flame retardant cable. With the development of science and technology, technology is also constantly in arguments in the United States and Europe. Europe, for example, introduced more than a CMP EN 50289-4-11 standard strictly, and are establishing suitable for all kinds of cable standard of CPD series high flame retardant, high if match with low smoke halogen free cable, so can imagine: building cable in the future will not be easy to decompose, and even break down will not release large amounts of gas and smoke. It should be said that this is currently in the field of integrated wiring cable coveted goal.

Servo motor control system cable

In recent years, the development and use of servo cable system is not only greatly improve the production efficiency of cable manufacturing but also for our enterprise has brought many convenient and save the cost. To develop a suitable factory production of excellent servo system is the problem all engaged in the manufacturing enterprise need to solve.

What is servo system, I believe most people slightly, but here I think it is necessary to make detailed interpretation for everybody. The servo system is used to precisely follow or a feedback control cable system in the process of repetition, also known as the servo system. In many cases, the amount of points to be controlled servo system is mechanical displacement or displacement velocity and acceleration feedback control system, its role is to make the output tracking input displacement mechanical displacement accurately.

At the same time, the structure of the servo system, and other forms of feedback control system there is no difference in principle. Servo system is first used in the automatic navigation of the ship, gun control, and the director, then gradually spread to many areas, especially in automatic lathe, the antenna position control, the guidance of missile and spacecraft, etc. The Servo motor cable system is mainly in order to achieve the following objectives: (1) with small power command signals to control the power load. Gun control and the rudder control is a typical example. (2) in the absence of mechanical connection, controlled by the input shaft is located in the output shaft, the distance the synchronous transmission. (3) the output mechanical displacement accurately tracking signals, such as records and indicating instrument, etc.

The development of PV cable

In all types of solar cells, produce direct current (dc) and need to convert alternating current (ac). In recent ten years, the global solar power market growth, and photovoltaic cable is not gb standard, so can reference standard and test, need to adjust, especially should pay attention to the cable long exposure to strong ultraviolet rays of ageing problems.

PV cable are often exposed to sunlight, the solar energy system is often used in harsh environment conditions, such as high temperature and ultraviolet (uv) radiation. In Europe, sunny days will result in the solar system in the field temperature as high as 100 °C. At present, we can use all kinds of material with PVC, rubber, TPE and cross-linked with high quality material, but unfortunately the rated temperature of 90 °C rubber cable, and even the temperature of 70 °C rated PVC cable is also often used outdoors, the national golden sun project horse, there are many contractors in order to save costs, not to choose cable specially used for solar system, choosing instead to replace the ordinary PVC cable photovoltaic cable, obviously, this will greatly affect the service life of the system.

The characteristics of photovoltaic cable is by its special cable insulation and sheath material, we call it a crosslinked PE, after irradiation accelerator irradiation, the molecular structure of the cable material will change, providing the aspects of performance. Mechanical load, in fact, during the period of installation and maintenance, cable can be on the edge of the roof structure of sharp wiring, cable at the same time must be under pressure, bending, tension, cross tensile load and strong impact. If the cable sheath strength is not enough, the cable insulation layer will be seriously damaged, which affects the service life of the whole cable, or cause a short-circuit, fires and injuries and other issues.

Wire and cable braiding

Wire and cable is mainly composed of conductive wire core, insulation, sheath layer, the three basic structure elements. There is no strict boundaries difference between the wire and cable, but speaking from a broad meaning, cable structure is complex, it has complex sheath layer, and some only conductor and insulation wire structure is simple, some only braid light armor layer or coating a layer of light soft armor layer. The conductive wire core wire and cable is used for the transmission of current. To reduce the power loss and voltage drop, conducting wire core general selection of high conductivity copper and aluminum. The role of the insulating layer is to prevent the current along the radial leakage, ensure use safety. Therefore, insulation required to have good electrical insulating properties, heat resistance and mechanical strength.

Outside the insulated wire core or a cable core protection layer called the sheath of the cable. Main function is to protect the insulation sheath. Its main performance is moistureproof, prevent oil, anti-corrosion, Anti aging, sun fire resistant, as well as mechanical protection. It sustain tension, knock against, but also has the electric and magnetic resistance etc. From the perspective of cable sheath, weaving is many kinds of wire and cable sheath or one of the outer sheath. However, according to the materials used in wire and cable braid and different parts in the structure of wire and cable, the role of the braid is obviously different.

For wire, fiber braid is a form of the light cover. Its main function is to protect the insulation is not affected by or less by all kinds of light, heat, moisture, low temperature, acid and alkali gases such as erosion and external mechanical force damage, ensure the safety of the electric wire. For the cable, fiber braid is often in the middle of the protective layer, so as to gain strong protective layer of the tear strength, such as enhanced sheath is in the middle of the rubber or plastic sheath in cotton yarn, hemp fiber braid, in order to improve the strength of the sheath. Metal braided layer are mainly copper braid and wire woven layer.

Relations between sheath thickness and quality of the cable

As we all know, the product quality, advantages and disadvantages, the first characteristic is reflected from the appearance of the product quality, no matter the product or semi-finished products, must paid attention to the appearance and the quality in production, implemente strict control and inspection. Sheath is the appearance of the Flex cable, the requirement is smooth and rounded appearance, uniform luster, unbiased core shall not exceed the stipulated deviation, no mechanical damage, flattening, perception of visible without sundry, bubble, sand holes, clear grain, bamboo, twist, etc.Sheathed in addition to meet the quality requirements, quality of cable sheath thickness also has certain influence.

Sheath thickness less than standard requirement, of course is not qualified, but the thickness is beyond standard request, it also is not qualified. For example: cable type for ZR - KVVP 4 * 1.5 was, by the measured average thickness of sheath thickness of 1.6mm, this model as reference to GB9330-88 standard request, the thickness should be 1.2mm. For the unqualified reason has the following points:
(1) Reduce the service life. When Cable laying after a long time electricity, electricity will generate heat, conductor allowed working temperature is 70 ℃, polyvinyl chloride (PVC) long-term use of temperature should not exceed 65 ℃, if in the summer, the temperature will rise, the temperature will be through the outer sheath, and sheath thickness increase, the heat is difficult to send out, then it will affect the service life of the cable, because of PVC under the action of heat, has brought a series of physical and chemical changes in the insulating layer, lost the original fine performance, cause the insulation performance significantly lower, even a short circuit, affecting the normal operation of the unit.
(2) The material performance defects. Material performance is not reflected by thickness, according to the GB8815-2002 standard requirements, one of the indicators is not up to standard and flame retardant PVC material, its oxygen index is less than 30.
(3) The control cable structure exist problems. If conductor, insulation, weave density, according to the standard control, selecting the appropriate filling material make it round, how can such sheath packed so thick?
(4) Increase the difficulty of cable laying. Now give priority to with bridge or wear tube cable laying, many companies are now in a cable tight, small diameter, has space during the installation process, send out heat, guarantee the cable outer sheath is not damaged, otherwise, bring some difficulties in the construction unit and cable laying.
To sum up, the thickness of sheath shall be in accordance with the standard controls, it can not only save resources, reduce material consumption, increase profits for the enterprise, but also can ensure the quality of cable, create a high quality and low price products.

The future trends of THHN cable

Wire aging is a common problem because most people for the lack of electricity, so the understanding of this aspect is not enough.
Due to aging power cord so the fundamental problem is damaged, which occurs after the leakage, and the phenomenon of power consumption, surface is, the electric meter speed is accelerated, resulting in increased power consumption, increased the cost of living, but this is not the most important, the most important thing is that, because of aging wire hides in the wall, when combined with the original wiring may cut corners, did not wear caused by pipe protection solution resulting in aspects such as wall charged, even can make the person get an electric shock, produce risk.This is very serious.

For this method, are generally choose replace the wires.But modern decoration are generally of wiring, replacing equivalent remodeling.It is relatively high costs and use a certain fixed number of year will repeat.If you do not have conditions to decorate, in order to later change with convenient also only choose cloth.But today is the 21st century, the modern years family decorate a style are also quite modern, if open wire is bound to affect the whole beautiful decoration. THHN cable will be the best choice.

Correct selection of shielded cable and not shielded cable

Screen cable and the shield, and exactly what kind of cable for copper structured cabling network provides the best solution, in the industry has been a long time. Choose unshielded twisted pair (UTP) cable and foil twisted-pair (FTP), or the United States the well-known shielded twisted-pair cable (ScTP) is not an easy decision. In fact, from a variety of options, select the appropriate shielding technology, and ensure the correct installation and operation of the technology, has been far more important than the choice of the FTP or UTP.

General practice is different all over the world. In Britain, most of Europe, the United States and Asian countries, usually the UTP cable as the most economical, and enough to satisfy most of the installation requirements of options. In Germany and other European countries, including France, Switzerland and Austria, FTP is dominant. When installing a system, one of the real problem is data integrity. The basic goal of shielding system is to prevent the potential electromagnetic interference (EMI) of data, such as industrial facilities and airports and operation key systems, such as military bases and the hospital.

Design and install the correct FTP wiring network will undoubtedly improve the signal integrity on shielding system. However, Jiansu Yafei Wire & Cable Co., Ltd alert users, in order to work efficiently, shielding grounding must be correct. In fact, this is not always easy to achieve. Bad earth shielding system will actually start using the shielding system provides worse performance levels. In the worst case, the block itself could become a radiation source, generates current grounding loop, or receive the surrounding radiation, the new data Cable of the phase led to harmful interference.

The type of shielding
Shielding is divided into several different types. Two or more conductor or four cable can pack into a whole block. In addition, the stranded cable each line also can block alone. In addition, these separate shielded cable can or can't cover the second overall shield. Whatever the design, in order to ensure effectiveness, shielding must be from end to end on the electron is continuous, and properly grounded. When choosing shielding wiring system, choose the overall end-to-end solutions is also very important. The different systems of mix component, may be caused by the impedance mismatch problem. Shielding system cost, including the required additional installation work, usually the same UTP solution for 20-30%.
