What Are the Measures to Prevent Electrical Power Cable Damage in Cold Weather?

1. Cold weather leads to damage to electrical power cables


The weather is cold. When laying and installing electrical power cables, many construction workers will find that the electrical power cable products of good quality often have some phenomena such as hard wires and peeling off of the insulating sheath. Many construction workers think it is the electrical power cable product itself. There are quality problems, and cable manufacturers also insist that the products have been inspected before leaving the factory and are qualified products, which often leads to misunderstandings between the two parties.


In fact, it is not the quality of the product itself that is wrong, but the severe cold in winter. The outer skin of electrical power cable products is mostly ordinary plastic or rubber. When they are in a sub-zero environment, they will become hard, and the entire electrical power cable product line will become hard and brittle, resulting in the outer skin may appear in the case of slight external force. Falling off damaged. If the electrical power cable product is placed outdoors or directly on the ground, the outer skin of the product is likely to fall off. So, how can we prevent the phenomenon of falling off the outer sheath of the electrical power cable in winter?


2. Measures and methods to prevent electrical power cable damage


Shipping from the factory: When electrical power cable products are shipped from the factory and loaded on the transportation vehicle, heat preservation and protection measures are required. For example, use a closed transport tool to prevent the product from being directly exposed; put a layer of soft cushion on the product, such as a quilt or other soft foam; big. When arriving at the destination or the construction site, the product supplier had better send personnel to supervise to prevent rough operation behavior when the product is unloaded.


Storage: It is best to store the product indoors, and at the same time, lay a layer of isolation layer on the storage surface, such as wood, bedding, foam, etc., to prevent the product from being frozen and damp, and pay attention to prevent the product from direct contact with the ground. Scratches, handle with care.


When laying and installing electrical power cables: it is best to choose to work when the temperature is warm in the middle and afternoon. If conditions are available, use a heater and other equipment to "warm up" the product in advance before use, so that the product can reach the best performance state. If it is buried in the ground, a protective layer, such as cloth and foam, can be laid in the cable trench in advance. If it is a pipe, make sure that the inside and outside of the pipe is smooth so that the wire will not be scratched. Special attention should be paid to iron pipes. When purchasing iron pipes of qualified quality, there may be a large number of sharp protrusions inside the iron pipes of poor quality, which are very likely to scratch the outer skin of the wires.
