The invention provides a high-voltage direct current polypropylene cable material, which comprises the following components in parts by weight: 100 parts of a copolymerized modified polypropylene material and 0.5-1 part of an antioxidant. The high-voltage DC polypropylene cable material in the present invention adopts the copolymerized polypropylene directly produced by the petrochemical plant as the insulating material, and adds antioxidant, which has excellent mechanical properties and electrical properties, and can replace the cross-linked polyethylene as the insulating material of the high-voltage cable. , and the polypropylene copolymer is a thermoplastic material, which is environmentally friendly, and the cable can be recycled and reused after decommissioning, which reduces the cost of using the cable material. |
