Abstract

The invention relates to a medium voltage heat dissipation cable. The heat dissipation cable includes an aluminum alloy conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer, a semi-conductive mineral cushion, an embossed aluminum sleeve with an asphalt anticorrosive coating, an outer sheath with embossed patterns and a heat dissipation coating layer; and the heat dissipation coating layer includes 54-65 parts of epoxy resin, 30-44 parts of organic silicone resin, 22-28 parts of polyethersulfone resin, 15-24 parts of heat dissipation powder, 10-18 parts ofFeO-SiO2 compound powder, 5-10 parts of modified micron order zirconia, 1-5 parts of a levelling agent, and 1-5 parts of a coupling agent. Through the changing of the structure of the cable and the application of a heat dissipation material, the heat dissipation of the cable can be effectively accelerated during the operation of the cable, the self-temperature of the cable can be reduced, the current-carrying capacity of the cable can be enhanced, and therefore, a conductor cross section and a cable outer diameter can be reduced.

Description

technical field [0001] The invention relates to a cable and a material for the cable, in particular to a heat dissipation cable and the heat dissipation material for the cable and a preparation method thereof. Background technique [0002] In the wire and cable industry, the conductors in the past mainly used copper and aluminum. Aluminum alloy is a conductor material that has only been widely used in recent years. In comparison, the electrical and mechanical properties of copper core conductors are superior to aluminum and aluminum alloy conductors. However, limited to the high price of copper, the application of aluminum alloy conductors has been accelerated. The electrical performance of aluminum alloy is equivalent to that of aluminum conductor, but its mechanical performance is completely superior to that of aluminum conductor. However, the ampacity of the aluminum alloy conductor is much smaller than that of the copper conductor, so the cross section of the aluminum ...
