Product Description
The XJ-30A type 125 ℃ medium voltage 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., fully mixed by an internal mixer. The insulation layer of medium voltage cables used in mining, marine and other industries meets the requirements of the XJ-30A type product in GB7594-87 standard, and has excellent process performance.
Product Usage
This product can be used as insulation material for marine cables and mining cables with a voltage of 6 kV and below, and 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, but other color products can also be provided according to user requirements.
