How to avoid out coat cracking in cold winter

The outer sheath of cable may be cracked in some certain extreme cold climate since the coat adopts mostly PVC or rubber which becomes harden and brittle under cold conductions. In winter, especially in northern areas, the outdoor temperature is often below zero degrees, so it is necessary to avoid the damage. And following methods are recommended in cold weather:

Characteristics of aluminum alloy cable

The aluminum alloy is the product of professional metal smelting factory. Its advantages are as follows.

Items need to be inspected during the acceptance of wire and cable.

Wires and cables are the main carriers of power and signal transmission. There is no strict boundary between "wire" and "cable". The smaller diameter, less number of cores, simple structure of the product to be called wire usually, while the one who has no insulation sheath to be called bare wire. The wire with a larger Cross-sectional area (greater than 6 square millimeters) is called large cable, and the one with a smaller cross-sectional area (less than or equal to 6 square millimeters) is called small wire, also known as distribution line. 

Brief introduction of prefabricated branch cable

The prefabricated branch cables are produced by professional production equipment with special designed molds. The branch joints are bonded to the original outer sheath layer of the main and branch cables to form a whole. Compared with the traditional treatment of cable branch joints or more advanced bus bar channel skills that carried out on spot, the said product has many advantages:
