Black XLPE Compound for MV Power Aerial Cable

Product Description:

Application	It is made by mixture, plasticization and granulation with the low-density polyethylene as the basic resin mixed with carbon black master batch, cross linking agent and other additives. It doesn’t contain harmful substances like heavy metal and has excellent mechanical, electrical and heat aging properties with the stable technique as well as smooth surface. It is used as the insulation of aerial cable.
