| Silane crosslinkable semi-conducting compound for medium voltage cable screening applications This is a silane crosslinkable semi-conducting polyethylene compound to be used in conjunction with silane crosslinkable insulation material for bonded shielding purposes. It is a single component system comprising a silane grafted ethylene polymer known as the graft compound SX539. Crosslinking occurs in the presence of moisture by migration of catalyst from the adjacent core insulation layer.&& |
