Causes and Preventive Measures of Wire and Cable Damage in Winter

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. So, how can we prevent wire and cable skins from falling off in winter? Tips for Peninsula Cable:
1. Ex factory transportation: when the product is loaded onto the transportation tool after delivery, it needs thermal insulation and protection measures. For example, use closed transportation tools to prevent direct exposure of products; Put a layer of soft cushion on the product, such as bedding or other soft foam; Handle with care during loading. Do not load the goods roughly. At the same time, avoid excessive bending of the products. When arriving at the destination or the construction site, the product supplier should send personnel to supervise, so as to prevent rough operation during product unloading.

2. Storage: It is better 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, and pay attention to prevent the product from scratching the outer skin of wires and cables by direct contact with the ground. Handle with care.

3. When laying and installing products: it is better to work in the middle and afternoon when the temperature is warm. If conditions permit, the product can be "warmed up" with a heater and other equipment before use, so that the product can reach the best performance state. If it is buried underground, a protective layer, such as cloth and foam, can be laid in advance in the cable trench. In case of pipe threading, it is necessary to ensure that the inside and outside of the pipe are smooth in advance, so as not to scratch the wire. Special attention should be paid to the iron pipes. The iron pipes with qualified quality may have a large number of sharp points in the iron pipes with poor quality, which may scratch the wire skin. To make a long story short, in winter, the wires and cables will become very fragile, and we need to "take care of".
