Embodiment 1

[0006] Embodiment 1: The steel core of the steel core aluminum stranded wire is covered with an insulating layer to insulate the load-bearing steel core wire from the aluminum wire. The load-bearing steel core wire is directly used as an electric heating wire, and the aluminum wire is stranded outside the insulating layer. The insulation layer is a high-voltage cable paper insulation material. The production process and equipment can be adjusted slightly on the basis of the original products.

Embodiment 2

[0007] Example 2: The steel core of the steel core aluminum stranded wire is covered with an insulating layer to insulate the load-bearing steel core wire from the aluminum wire, and the load-bearing steel core wire is directly used as an electric heating wire, and the coated insulating material is mixed with 0.1 -12% beryllium oxide powder to improve the thermal conductivity of the rubber insulation layer; the insulation layer is twisted with aluminum wires. The production process and equipment can be adjusted slightly on the basis of the original products.

Embodiment 3

[0008] Example 3: For aluminum stranded wire and 10-70mm 2 The original structure of the steel core aluminum stranded wire is a steel core wire and 6 aluminum wires. The invention uses a nickel-chromium alloy heating wire and an iron-chromium aluminum alloy heating wire as an electric heating wire, an electric heating wire The coated plastic insulation layer is mixed with 1-12% beryllium oxide fine powder to improve the thermal conductivity of the insulation layer. This alloy heating wire is used to replace the steel core wire of the steel core aluminum stranded wire, and it also plays a role of load bearing and heat tracing; Stranded aluminum wires outside the insulation layer. Among them, the specifications of the heating wire are matched with the aluminum wire, and the insulation layer is matched according to different transmission voltage levels; the production process and equipment are in aluminum stranded wire and 10-70mm 2 On the basis of the steel core aluminum stranded wi...

Abstract

The present invention provides an electric power transmission line which can prevent the ice rain and the freezing of the dissolved snow. An electric heating line is arranged when the electric power transmission line (mainly the aluminum stranded wire and the aluminum cable steel reinforced and the like for overhead electric power transmission) is produced. The electric heating line coats the organic composite material which has excellent electric insulating property and high thermal conduction coefficient for replacing one or a plurality of steel wires in the aluminum cable steel reinforced and using as a bearing wire. In the normal meteorological condition, the electric heating wire has the advantages of non-conducting, no working, no effect to the operating efficiency of the electric network, no increasing the loss of the system and functioning for bearing the steel wire in the aluminum cable steel reinforced. When the heavy weathers of ice rain, snowstorm and the like occur and the electric network line is generated with ice rain, dissolve-snow freezing, the power transmission line has the advantages of supplying power for the electric heating line, providing heat to the electric transmission line through the electric heating wire, sustaining the surface temperature of the electric power transmission line above zero, melting the ice bear by the electric power transmission line, preventing the refreezing of the ice rain and the dissolved snow on the electric power transmission line and preventing the generation of the overloading accident of the circuit bearing ice. In this way, though the electric power loss of the electric network in the heavy weathers of ice rain, snowstorm and the like is increased, the safety of the electric facility is guaranteed. The normal operation of the electric facility in heavy meteorological condition is guaranteed.

Description

Technical field [0001] The invention relates to a transmission line for preventing freezing rain, melting snow and freezing, and belongs to the field of power transmission equipment. 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, it can be easily converted to other kinds of energy, and it is also easy to operate and control when in use, and 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 communications, and people's lives, electric energy has been increasingly widely used and a large number of applications. It can be said that electrification is a highly mechanized and automated production process. The use of the latest scientific and technological achievement...
