In the cold winter, many construction personnel will find that when laying and installing wire and cable, usually good quality wire and cable products, there will often be some wire body hard, insulation peeling damage and other phenomena, many construction personnel think that the wire and cable products themselves have quality problems, and cable manufacturers also insist that the product has been tested at the factory, is a qualified product. Often leads to misunderstandings between the two parties.

In fact, it is not the quality of the product itself, but because of the cold winter. The outer skin of wire and cable products is mostly ordinary plastic (PVC) or rubber, when they are in a sub-zero environment, it will harden, and the entire wire and cable product line will be hard and brittle, resulting in the outer skin may fall off and be damaged in the case of slight external force. In winter, especially in the northern region, the outdoor temperature is often below zero, and 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 phenomenon of product peeling will occur. Qingdao Tianxing cable to explain to you the correct measures to prevent winter wire and cable peeling phenomenon

1, factory transportation: When the product is loaded on the transport vehicle, it needs warm and protective measures. For example, the use of closed transport vehicles to prevent direct exposure of products; Put a layer of soft cushion on the product, such as bedding or other soft foam; Handle gently when loading, do not rough loading, while avoiding excessive bending of the product.

2. When arriving at the destination or the construction site, it is best for the product supplier to send personnel to supervise and prevent the rough operation behavior when the product is unloaded.

3, storage: it is best to store the product indoors, and at the same time, lay a layer of isolation layer on the surface of the storage, such as wood, bedding, foam, etc., to prevent the product from freezing and moisture, pay attention to prevent the product from direct contact with the ground will scratch the wire and cable skin phenomenon, gently handle.

4, product installation: it is best to choose in the middle of the afternoon temperature warmer operation, if conditions can be used before the use of heaters and other equipment to give the product "warm up", so that the product to achieve good performance. If it is buried, a protective layer, such as cloth and foam, can be laid in the cable trench in advance. If it is through the tube, it is necessary to ensure that the inside and outside of the tube are smooth in advance, so that the wire will not be scratched. In particular, the iron pipe should pay attention to the purchase of qualified iron pipes, poor quality iron pipes may have a large number of sharp bumps in the tube, which is likely to scratch the wire skin.

5, the selection of Puguang brand low-temperature cable, in strict accordance with the standard "GB/T2951.14-2008" test requirements for testing, placed in an environment of minus 35℃ for 16h, and then mechanical properties test, repeated bending and bending, insulation and sheath elongation and tensile test, pass rate of 100%, Puguang low-temperature cable has low temperature resistance, can be in a cold external environment, insulation and sheath skin can still ensure no cracks, no break state.
