A best formula of water-tree-retardant cable insulation material was determined by studying the effects of PE base material, crosslinking agent, assistant crosslinking agent and antioxidant on the proper-ties of cable insulation material, including 100 phr low density polyethylene(LDPE), 1.5 phr ethylene-acryl-ic acid copolymer(EAA) as water-tree-retardant, 0.6 phr sorbitol(DBS), 2.2phr dicumyl peroxide(DCP) as crosslinking agent, 1.6 phr triallyl cyanurate(TAC) as assistant crosslinking agent and 2.8 phr antioxidant 300. The comprehensive properties and accelerated aging properties of the water-tree-retardant cable insula-tion material prepared by the best formula were tested. The results show that the properties of the cable insulation material can meet the national standard requirements, and the life of the prepared cable pro-longs obviously, with no less than 40 years of life.
