Abstract: Peroxide-crosslinked polyethylene (XLPE) was obtained with LDPE as base material, carbon black (CB), dicumyl peroxide (DCP) and antioxidant as assistants. The influences of CB content on XLPE′s properties including mechanics, electricity, thermal stability and weather resistance were studied by tension machine, insulating oil dielectric tester, schering bridge, high resistance meter,thermal aging oven,Xenon weatherometer et al. It was found that,with increasing of concentration of carbon black, mechanical property had no obvious change; weather resistance were improved notably; electric strength and volume resistivity gradually decreased;relative permittivity and dielectric dissipation factor increased obviously. When carbon black content was 1.8%, the insulating property and weather resistance approached optimal balance. And, using compounds of carbon black and certain sulfur-containing antioxidants, the thermal aging property of XLPE was significantly improved.
