摘要： A flame retardant polyolefin compound having low smoking and toxicity comprising 100 parts by weight of polyolefin resin, 100 to 150 parts by weight of a flame retardant, and 2 to 10 parts by weight of zinc stannate as a flame retardant auxilliary agent. The flame retardant polyolefin compound preferably uses a composite metal hydroxide as the flame retardant.

摘要： A crosslinked polyolefin insulated power cable with remarkably improved AC breakdown voltage and impulse withstand voltage has been obtained by a process which comprises extrusion-coating, on the outer surface of a conductor, (1) a material for the formation of an inner semiconductive layer, comprising a base polymer and N-vinylcarbazole, (2) a crosslinkable polyolefin material for the formation of a crosslinked polyolefin insulating layer and (3) a material for the formation of an outer semiconductive layer in this order and then subjecting the coated conductor to a crosslinking treatment to form, on the outer surface of the conductor, an inner semiconductive layer, a crosslinked polyolefin insulating layer and an outer semiconductive layer in this order.
