  • Description
  • Product Description  
    The XJ-30Z 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, softeners, fillers, anti-aging agents, vulcanizing agents, etc., and is fully mixed by an internal mixer. It is used for the insulation layer of cables with 10 kV and below used in coal mines. This product has excellent heat resistance, ozone resistance, and electrical insulation properties, and is easy to process and store.  
    Product Usage  
    This product is a specialized insulation material for coal mine cables below 10 kV, which can be used for a long time at temperatures ranging from -40 to 90 ℃. This material has high flexibility, is easier to bend and move, and is convenient for cable installation and laying. The color is originally white (for color recognition), and other color products can also be provided according to user requirements.
