Winter on April 28, 2022 New energy cable How to prevent damage
In the cold winter, when laying and installing wires and cables, many construction personnel will find that some wires and cables with good quality usually appear hard, insulation skin falls off and is damaged. Many construction personnel think that there is a quality problem with the wires and cables themselves, and cable manufacturers insist that the products have been inspected before delivery, It is a qualified product, which often leads to misunderstanding between both parties.
In fact, it is not the quality of the product that has gone wrong, but the severe cold in winter. The skins of wire and cable products are mostly ordinary plastic (PVC) or rubber. When they are in an environment below zero, they will become hard, and the whole wire and cable product body will become hard and brittle, which may cause the skins to fall off and be damaged under slight external forces. In winter, especially in northern areas, the outdoor temperature is often below zero, and the surface temperature may be lower. Therefore, if the wire and cable products are placed outdoors or directly on the ground, the product skin may fall off.
