During the winter cold, many builders will find that when they install wire and cable, usually good quality wire and cable products, often appear some line body hair hard, insulation skin loss and other phenomena, many construction personnel thought is the wire and cable products itself appeared quality problems, and cable manufacturers also insist that the products in the factory has been tested , is a qualified product, often lead to misunderstanding between the two sides.

In fact, not the quality of the product itself what the problem, but because of the winter cold caused. Wire and cable products are generally plastic (PVC) or rubber, when they are under 0 degrees under the environment, it will harden, the entire wire and cable product line will be hard, brittle, resulting in the skin may be a slight external forces will appear off damage. In winter, especially in the north, the outdoor temperature is often below 0 degrees, the surface temperature may be lower, so if the wire and cable products are placed outdoors or directly on the surface, it is likely that the product skin shedding phenomenon. So how do we prevent the winter wire and cable from peeling off the phenomenon? The following measures are taken from all stages

1, ex-factory transport: in the product shipped to the delivery tool, the need for warmth and protection measures. For example, the use of closed means of transport to prevent direct exposure of products, to the product pad on a soft cushion, such as bedding or other soft foam, etc., when loading lightly handle, do not rough loading, while avoiding the product appears to bend too much.

2, to arrive at the destination or construction site, the best supplier of the product to supervise, to prevent the product unloading when the rough operation behavior.

3, Storage: The best place to store products indoors, at the same time in the storage of the surface spread on a layer of isolation, such as wood, bedding, foam and so on, to prevent the product from freezing damp, pay attention to prevent the product and the ground directly contact the wire and cable skin scraping phenomenon, light handle

4, the installation of products installed: the best choice in the afternoon temperature warmer in the case of the operation, if conditions can be used before the use of warm air heaters and other equipment in advance to the product "warm up", so that the best performance of the product status. If it is buried, in the cable trench can be laid in advance a layer of protective coating, such as cloth, foam. If you are wearing pipe, you have to ensure that the line tube inside and outside the smooth, not to the wire scratches. In particular, the iron pipe should pay attention to the purchase of quality steel pipe, poor quality of the pipe pipe may have a large number of sharp points, most likely to the wire skin scratch.

5, the use of light brand Low-temperature cable, in strict accordance with the national standard "gb/t2951.14-2008" Test requirements for testing, in the 零下35℃ environment to place 16h, and then carry out mechanical performance test, the repeated bending of the flex, insulation and sheath for elongation and tensile test test, Through the rate of 100%, Pu-light low-temperature cable has a very strong low-temperature resistance, can be in the cold outside environment, insulation and sheath skin can still ensure no cracks, no break state.

To make a long story short, in the winter, wire and cable will become very fragile, we need to "care".
