Abstract

The invention discloses a graphene-containing high heat conduction polyvinyl chloride sheath material for a cable, and a cable with the graphene-containing high heat conduction polyvinyl chloride sheath material. The graphene-containing high heat conduction polyvinyl chloride sheath material reduces electric energy transmission loss. The graphene-containing high heat conduction polyvinyl chloride sheath material comprises, by mass, 100 parts of polyvinyl chloride resin, 0.05-3 parts of a heat conduction agent, 8-9 parts of an auxiliary heat conduction agent, 20-25 parts of a plasticizer, 0.1-0.5 parts of an anti-oxidant, 2.2-2.9 parts of a stabilizing agent, 0.5-3 parts of a lubricant and 37-53 parts of a filler. The cable sheath layer comprises polyvinyl chloride resin, a heat conduction agent, an auxiliary heat conduction agent, a plasticizer, an anti-oxidant, a stabilizing agent, a lubricant, a filler, a fire retardant and a pigment assistant. Compared with the existing sheath material, through cooperation of the heat conduction agent and the auxiliary heat conduction agent, the graphene-containing high heat conduction polyvinyl chloride sheath material has higher heat conductivity of 0.3W/mk or more and good heat dispersion effects, and reduces electric energy transmission loss or improves a cable current-carrying capacity.

Description

technical field [0001] The invention relates to a cable sheath material and a cable made of the material, in particular to a polyvinyl chloride sheath material for a cable and a cable made of the material. Background technique [0002] Because of the resistance of the conductor material of the power cable, when the cable transmits current, the resistance of the conductor will generate heat. The greater the current, the more heat the conductor will generate, and the temperature of the conductor will also increase. As the temperature increases, the DC resistance of the conductor will also increase. , and the increase in DC resistance will generate more heat, and the loss caused by the temperature rise of the conductor during the power transmission process accounts for about 15% of the transmitted power. Reducing the temperature of the conductor can reduce the loss of electric energy, so it is of great significance to reduce the temperature of the cable conductor. The importan...
