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...

Examples

Embodiment 1

[0021] like figure 1 As shown, a hydrophobic and anti-icing high-voltage transmission line includes a metal twisted cable core 1 composed of several metal wires, an electric heating cable 3, a sheath layer 4 and a hydrophobic anti-icing layer 5. The metal twisted wire The outside of the cable core 1 is provided with an insulating layer 2, and a filling layer 6 is provided between the metal stranded cable core 1 and the electric heating heating wire 3. The metal stranded cable cores 1 are arranged in a circle, and the electric heating heating wire 3 is one, which is arranged at the center of a circle surrounded by several metal twisted cable cores 1 . The electric heat tracing wire 3 and the metal twisted cable core 1 are arranged in the sheath layer 4. When the power transmission cable freezes, the electric heat trace wire energizes the electric heating wire, the electric heat trace wire generates heat, and the power transmission cable The melting of ice and snow realizes aut...

Embodiment 2

[0024] like figure 2 As shown, a hydrophobic and anti-icing high-voltage transmission line includes a metal twisted cable core 1 composed of several metal wires, an electric heating cable 3, a sheath layer 4 and a hydrophobic anti-icing layer 5. The electric heating cable 3 is two, and the metal twisted cable core 1 is several, which are arranged on the periphery of the two electric heating cables 3 . When ice is formed on the transmission cable, the electric heating wire energizes the electric heating wire, and the electric heating heating wire generates heat, which melts the ice and snow on the transmission cable, realizes automatic deicing, reduces the weight load of the transmission cable, and improves Ensure the safety of power transmission and ensure the normal supply of electricity for production and living.

[0025] The hydrophobic anti-icing layer 5 is arranged outside the sheath layer 4, and the hydrophobic anti-icing layer 5 is provided with vertical water grooves...
