Winter is cold, and many construction workers will find that the wire and cable products that are usually of good quality often have phenomena such as hardening of the wire body, peeling and damage of the insulation skin, ETC. when laying and installing wires, and cables. Many construction workers think there is a quality problem with the wire and cable products themselves, and the cable manufacturers also insist that the products have been inspected when they leave the factory and are qualified products, which often leads to misunderstandings between the two parties. It is not a problem with the quality of the product itself, but due to the severe cold in winter.
The outer skin of wire and cable products is mostly ordinary plastic (PVC) or rubber. When they are in an environment below zero degrees, they will harden, and the entire wire and cable product line body will harden and become brittle, resulting in the possibility of peeling and damage to the outer skin even under slight external force. In winter, especially in the northern regions, the outdoor temperature is often below zero, and the ground temperature may be lower. Therefore, if the wire and cable products are placed outdoors or directly on the ground, it is likely that the phenomenon of product skin peeling will occur. So, how do we prevent the phenomenon of wire and cable skin peeling in winter? Take the following measures from various stages:
Factory transportation: When the product is loaded on the transportation tool when it leaves the factory, it must be warmed and protected. For example, use a closed transportation tool to prevent the product from being directly exposed to the outside; pad a layer of soft cushion for the product, such as bedding or other softer foam, etc.; load it lightly and gently, and do not load it roughly, and avoid the product from appearing too large. Bend.
When arriving at the destination or construction site, the product supplier should send personnel to supervise and prevent rough operation behavior when unloading the product.
Storage: It is best to store the product indoors, and lay a layer isolation layer on the ground where it is stored, such as wooden boards, bedding, foam, etc., to prevent the product from freezing and damp, and pay attention to prevent the product from directly contacting the ground. The phenomenon of scratching the wire and cable skin, handle with care.
When laying and installing the product: It is best to choose to work in the warmer temperature in the afternoon, and if possible, use equipment such as a hot air blower to warm up the product in advance before use, so that the product can achieve the best performance state. If it is buried, you can lay a protective layer in the cable trench in advance, such as cloth or foam. If it is a pipe, you must ensure the smoothness of the inside and outside of the pipe in advance, so as not to scratch the wire.
