How to choose insulation material for industrial cables?

When selecting the insulation material of industrial cables, various factors need to be considered to ensure that the cable can have good insulation performance and safety reliability during the working process. The following will introduce several common insulation materials and their selection points:

1. Polyethylene (PE) : polyethylene is a commonly used insulation material, with good insulation properties and electrical breakdown resistance, relatively high temperature resistance. When selecting PE as a thermal insulation material, it is necessary to consider its wear resistance, chemical corrosion resistance and other characteristics to adapt to different industrial environments.

2. Polyvinyl chloride (PVC) : PVC is a commonly used plastic material, with good heat resistance and insulation properties, suitable for general industrial cable insulation. When choosing PVC as a thermal insulation material, it is necessary to consider its weather resistance, flexibility and other factors to ensure the service life of the cable in different working environments.

3. Crosslinked polyethylene (XLPE) : XLPE is a material with excellent electrical properties and high temperature resistance, which is suitable for the insulation of high voltage cables. When choosing XLPE as insulation material, it is necessary to consider its insulation performance and electrical breakdown resistance to ensure that the cable can work stably in high voltage environments.

4. Silica gel: Silica gel is a kind of thermal insulation material with high temperature resistance and good weather resistance, which is suitable for cable insulation in high temperature working environment. When choosing silicone as a thermal insulation material, it is necessary to consider its oil resistance, torch resistance, anti-aging and other characteristics to ensure that the cable is safe and reliable in high temperature environment.

To sum up, when selecting the insulation material of industrial cables, it is necessary to comprehensively consider the working environment, working temperature, electrical performance and other factors of the cable, select the material with good insulation performance, heat resistance and weather resistance, and select it according to the specific circumstances to ensure that the cable has good insulation performance and safety and reliability during the working process.
