Causes and preventive measures for wire and cable damage in winter
2. When arriving at the destination or at the construction site, it is best for the product supplier to station personnel for supervision to prevent rough operation when the product is unloaded.
3, storage: It is best to store the product indoors, and at the same time put a layer of insulation on the stored surface, such as wood, bedding, foam, etc., to prevent the product from being exposed to moisture, pay attention to prevent the product from directly contacting the ground.

In particular, iron pipes should be noted that the purchase of qualified iron pipes may result in a large number of sharp raised points in the poor quality iron pipe, which may cause scratches on the wire sheath.
5, select Jiapu cable, strictly in accordance with the national standard "GB/T2951.14-2008" test requirements for testing, placed in the environment of minus 35 ° C for 16h, and then carry out mechanical performance test, it is repeatedly bent and flexed Tests for elongation and tensile strength of insulation and sheath, with a pass rate of 100%, Jiapu cable has excellent low temperature resistance, and the insulation and sheath skin can be guaranteed in a cold external environment. No cracks, no breaks.
