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. The purpose of Cable armoring layer is in addition to enhance tensile strength, compressive strength and other mechanical protection to extend the service life. Armored cable has a certain of external force resistance, can also prevent the mouse's tearing, not as to cause the power transmission problem through the armored.
