The importance of cable sheath

2019/11/29

Whether the cable is qualified needs to be judged from many aspects. On the premise that the material reaches the standard, the thickness of sheath is one of the judging factors. Then what kind of sheath is qualified?To understand this problem, first to understand the unqualified sheath and its impact on the cable, the following for everyone to analyze the cable sheath thickness of the unqualified harm to the cable

Hazard of unqualified sheath thickness:

1. Reduce the service life of wire and cable products

It is easy to understand that the insulation level and mechanical level of the thinnest point of the sheath will decline after long-term operation, especially when buried directly, immersed in water, exposed to the open air or corroded easily.

Add in routine sheath testing or an earthing fault, and the thinnest point may be broken.In this way, the protection of the cable sheath will be lost.In addition, the internal consumption can not be ignored, wire and cable long term electrification will produce a lot of heat.

2, increased the difficulty in the laying process

With the development of global industry, more and more environmental requirements must be outside diameter is small, high voltage cable products in the shop, there needs to be considered in the process of gaps, so you can send out the heat generated by the electric wire electric cable after electrify, sheath thickness too thick will affect the largest bending, thus increases the difficulty of laying, so the thickness of sheath requirements strictly comply with relevant standards, otherwise unable to protect the wire and cable.Can not blindly pursue its thickness.

What kind of sheath is qualified?

According to the above two kinds of analyses we can see that the product quality, the advantages and disadvantages, the first characteristic is reflected from the appearance of the product quality, the sheath is the appearance of the cable, the requirement is smooth and rounded appearance, uniform luster, unbiased core () shall not exceed the stipulated deviation, no mechanical damage, squash, no visual visible sundries, bubbles, sand holes, clear grain, bamboo, twist, etc.In addition to the above quality requirements, the thickness of sheath also has a certain effect on the cable quality.

It is well known that the function of the cable sheath is to protect the cable insulation core from damage under the action of external forces and play a protective role.If the thinnest point of the cable sheath does not meet the requirements, the cable sheath will be damaged before reaching the normal maximum external destructive force.If the cable is flooded due to the thickness of sheath, the whole cable will be scrapped if serious, because there is no effective way to deal with the cable water, so we must pay attention to the condition and quality of sheath when buying.
