Dewatering anti-icing high-voltage power transmission line

Abstract

The invention discloses a dewatering anti-icing high-voltage power transmission line comprising a metal twisted cable core formed by a plurality of metal conductors, an electric heating wire, a sheath layer and a dewatering anti-icing layer. The metal twisted cable core is externally provided with an insulation layer; the electric heating wire and the metal twisted cable core are disposed in the sheath layer; and the dewatering anti-icing layer is disposed outside the sheath layer, and is provided with a vertical water flowing groove. Power transmission is carried through the dewatering anti-icing high-voltage power transmission line; since the sheath layer is externally provided with the dewatering anti-icing layer, and the material has the excellent dewatering function, when the material is applied to a cable, the cable is allowed to have the waterproof antifouling anti-icing capabilities; and meanwhile, the electric heating wire in the cable can be used for heating the cable to melt the ice on the cable, and therefore, functions of the cable cannot be affected.

Description

technical field [0001] The invention relates to a transmission line, in particular to a hydrophobic and anti-icing high-voltage transmission line, which belongs to the technical field of high-voltage transmission cables. Background technique [0002] Electricity occupies a very important position in national construction, because electric energy can be conveniently and economically transmitted and distributed over long distances, and can be easily converted into other kinds of energy. It is also easy to operate and control when used, and it is compatible with various emerging Technology is inextricably linked. Therefore, in all sectors of the national economy, in all modern industrial and agricultural production, transportation, information and communication, and people's daily life, electric energy has been increasingly widely and massively applied. It can be said that electrification is a highly mechanized and automated production process, the technical basis for adopti...

Problems solved by technology

However, the existing prefabricated branch cables have the problem of poor waterproof performance during operation in special environments. After a long time, water will infiltrate the sheath and enter the interior of the cable to reduce the insulation performance, resulting in leakage or short circuit. , endangering safety. In addition, when the ambient temperature is low, the cable may even freeze during storage, which seriously affects the use and laying of the cable.
