The insulation layer of a cable is a very important part of the cable structure. It can effectively protect the conductors in the cable and prevent short circuits between the cable and the external environment or other conductors. Failure of the insulation layer will have a serious impact on the safety performance and service life of the cable.

The role of cable insulation layer

 

First of all, the function of the insulation layer is to prevent the cable conductor from direct contact with the surrounding environment, thereby avoiding cable aging or corrosion caused by chemical reactions between the conductor and other substances. If the insulation layer of the cable is unqualified, direct contact will occur between the conductor and the surrounding environment, which can easily lead to problems such as moisture, corrosion and short circuit of the conductor, seriously affecting the normal operation of the cable.

 

Secondly, insulation also prevents short circuits between cable conductors and other adjacent conductors. In a cable, there are usually multiple conductors, which need to be isolated by insulation layers to prevent current from bridging between the conductors, causing cable operation failures. If the insulation layer of the cable is unqualified, it will cause a short circuit between the conductors, cause abnormal current, and even lead to dangerous situations such as fire and explosion.

 

In addition, the insulation layer can effectively prevent wires that exceed the safe voltage from causing harm to the human body. As a device for transmitting electrical energy, XLPE Insulated cables usually transport high-voltage current. If there is no insulation layer for protection, the risk of electric shock will occur when the wires come into contact with the human body. Therefore, when designing and manufacturing cables, an insulating protective layer must be added to the outside of the cable to ensure that the human body will not be harmed by wires that exceed the safe voltage.

 

In short, the insulation layer of the cable plays a very important role in the cable structure. It protects the conductor from the surrounding environment and avoids short circuit problems, and also protects the human body from the hazards of high-voltage wires. Therefore, ensuring the quality of the cable insulation layer is of great significance to the normal operation and service life of the cable. Cable manufacturers should strictly control the quality of the insulation layer during the production process to ensure the safety and reliability of the cable. At the same time, users should also pay attention to the quality of the insulation layer when purchasing and using cables to avoid safety hazards caused by using unqualified cables.
