Product Description
The XJ-30G type 90 ℃ ethylene propylene rubber insulation material produced by our company is based on ternary ethylene propylene rubber as the basic material, supplemented with reinforcing agents, softening agents, anti-aging agents, vulcanizing agents, etc., and is fully mixed by an internal mixer. It is used for the insulation layer of wires and cables below 35kV. This product has excellent mechanical properties, heat resistance, ozone resistance, and electrical insulation properties, and is easy to process and store.
Product Usage
This product can be used as insulation material for marine cables with 35 kV and below, DC high-voltage cables for X-ray machines, electrostatic precipitator cables, locomotive and vehicle cables, mobile high-voltage cables, atomic generator cables, etc. It can be used for a long time at temperatures of -50~90 ℃. This material has high flexibility, is easier to bend and move, and is convenient for cable installation and laying. The color is orange.
