Winter cold, many construction workers in the laying and installation of wire and cable will find that the usual good quality wire and cable products, often appear some line body hardening, insulation sheathing damage and other phenomena, many construction workers think that the wire and cable products themselves have quality problems, and cable manufacturers also insist that the product has been inspected at the factory, is a qualified product, often leading to misunderstandings between the two sides.

In fact, not the quality of the product itself what went wrong, but due to the winter cold. The outer skin of wire and cable products are mostly ordinary plastic (PVC) or rubber, when they are in a sub-zero environment, they will harden, the entire wire and cable product line body will harden, become brittle, resulting in the outer skin may be damaged in the case of a slight external force are peeling. In winter, especially in northern areas, the outdoor temperature is often below zero degrees, the surface temperature may be even lower, so if the wire and cable products are placed outdoors or directly on the ground, it is likely that the product sheathing phenomenon. So, how do we prevent the phenomenon of winter wire and cable shedding outer skin?

Take the following measures from various stages:

1, factory transport: when the product is loaded onto the transport vehicle, the need to keep warm and protective measures. For example, the use of closed transport tools to prevent direct exposure of the product; to the product pad on a layer of soft cushions, such as bedding or other softer foam, etc.; loading lightly, do not rough loading, while avoiding excessive bending of the product.

2、When arriving at the destination or construction site, the product supplier had better send personnel to supervise to prevent rough work behavior when unloading the products.

3, storage: it is best to place the product in indoor storage, while in storage on the surface of a layer of isolation, such as wood, bedding, foam, etc., to prevent the product from freezing and moisture, pay attention to prevent direct contact between the product and the ground will be the phenomenon of scratching the outer skin of wire and cable, lightly.

4, product laying and installation: the best choice in the afternoon temperature is warmer in the case of operations, such as conditions can be used before the use of equipment such as heaters in advance to the product "warm up", so that the product to the best performance state. If it is buried, you can lay a layer of protection in the cable trench in advance, such as fabric, foam. If it is through the tube, you have to ensure that the smooth inside and outside of the line pipe in advance, not to scratch the wire.
