Several problems needing attention when install fire-resistant cables

Fire-resistance cable can still maintain the normal work of the line for a period of time under the condition of combustion, that is to say in case there is a fire, fire-resistant cable won't suddenly burning, it still can maintain the normal power supply for a period of time. This feature determines the fire-resistant cable playing an important role in modern urban and industrial construction, because once there is a fire, control, monitor, guide and alarm systems such power supply circuit must maintain normal work.

Fire-resistant cable applications:
Fire-resistant cable is mainly used in emergency power supply to the user of fire equipment, fire alarm equipment, ventilation and smoke exhaust, guide line lights, emergency power socket, the elevator for the emergency power supply circuit.
When stuff install a fire-resistant cable, they need to pay attention to the following questions:
1. When the fire-resistant cable used in cable populated cable tunnels, cable interlayer, or inflammable places near tubing, oil depot, fire-resistant cable shall, first of all, choose A category fire-resistant cable. Despite the situation, and the less number of cable configuration, should choose B type fireproof cables.
2. Most of fire-resistant cable used as emergency power supply circuit, the normal work of the requirements of fire. Due to the fire when the environment temperature has risen sharply, to ensure the transmission capacity of lines, lower pressure drop, long for the power supply circuit and the circuit of the voltage drop strictly limit allowed, fire-resistant cable should be at least one.
3. The fire-resistant cable cannot be used as a high temperature resistant cable.
4. In order to reduce cable joint failure probability in fire accident, you should try to reduce the amount of joint in the installation, to guarantee the normal work of the lines in the fire. If you need to do to branch connection, deal with joint completes the fire prevention.

PVC 0.6/1KV Multi cores power cable Black Friday sale

For conventional 300/500v, these a few 450/750v voltage wires are familiar with, but recently had a customer ask me for more than 0.6/1kv PVC core flexible power cable. Meet stringent electrical and mechanical performance requirements, at room temperature has good resistance to acid, alkali resistance and grease and other features. Material aspects using environmental protection material, in line with RoHs standard. Apply to the high load of electrical equipment connected, especially in the industrial environment can be installed with indoor dry wet electric system, but also be applicable to the outdoor fixed installation, especially suitable for the power cable Black Friday sale for the purpose of measurement and control of complex industrial environments, they use occasions such as: processing machinery, conveyor belt, line, engineering installation, air conditioning system, steel mills and rolling mills and so on.

Trailer cable in the United States Canada market

As is known to all, mobile transportation is convenient, especially apply to the construction units. Trailer coach originated in the United States, with the development of economy, our country also gradually developed in the mobile industry, and now there are a lot of enterprises needs to be exported to the United States, Canada and other countries.
Canada and the United States, need to export trailer to enterprise, must take the Canadian side of the market requirements into account, such as Trailer cable also need to match the market standard. The American market for trailer cable standard standard is UL719 and UL83, while the Canada market for trailer cable standard is CSA C22.2 N48 - M90, so their trailer cable type on the market are respectively the NM-B wire and NMD-90.
Anyte cable specializing in the production of national certification cable, including comply with UL certification NM-B and Canada CSA certification NMD-90D nylon wire. YAFEI's early discussing with mobile companies decided to this kind of trailer special cable listed as one of the certified products, and successfully passed that examination of the corresponding mechanism. If there is customer need to export trailer to the United States Canada, come to consult, Jiansu Yafei Wire & Cable Co., Ltd. will provide professional guidance according to your requirements.

How to choose the control cable?

With the rapid development of economy, people's choice of control cable and application put forward higher request, so how to choose and use the control cable?
Today according to different control cable outer sheath material, the control cables can be classified as: PVC control cable, natural-styrene butylbenzene rubber insulated control cable, polyethylene insulated control cable, cross-linked polyethylene insulation and ethylene propylene rubber insulated control cable. The PVC insulated control cable, cross-linked polyethylene and polyethylene insulation of conventional control cable, control cable, when Anyte cable is also widely used in the market. The control cable from different angles, they have different performances and applications.

The first is the use temperature is different: for ethylene propylene rubber insulated cable, the highest use temperature of conductor is 90 ℃; for PVC insulated cables and polyethylene insulated cable, conductor highest working temperature is 70 ℃; the crosslinking polyethylene insulated cable, its highest temperature is 90 ℃. For the use of different temperature control cable can affect the carrying capacity of the cable. From a security perspective, chosen with cross-linked polyethylene insulation and ethylene-propylene insulation cable is much better.

From the point of view of Environmental protection, ethylene-propylene insulation and crosslinked polyethylene insulated cable is halogen free, while PVC insulated cable containing halogen, so when a fire burning, containing halogen material cable smoke is poisonous. So for some people more concentrated occasions, such as the station, shopping mall, it is best to use low smoke zero halogen control cable. From the price point of view: the cheapest is PVC insulated cables.

Since Yafei cable established, focusing on the research and production of control cables, according to the requirements of polyvinyl chloride (PVC) control cable, xlpe insulated control cables and crosslinked polyethylene control cable has become the mainstream products of Yafei control cable. Customers from all walks of life can choose Corresponding material control cable according to the requirements and the performance all kinds of products in the above described.
