High-voltage rubber jacketed flexible cable for deicing device

Abstract

The invention discloses a high-voltage rubber jacketed flexible cable for a deicing device. The high-voltage rubber jacketed flexible cable comprises a power wire core conductor which is arranged in the center of the cable, wherein an inner shielding layer, an insulating layer and an outer jacket are sequentially sleeved outside the power wire core conductor; a conductive adhesive insulation shielding layer and an aluminum plastic composite belt are sequentially sleeved between the insulating layer and the outer jacket from inside to outside; and a drainage wire is arranged between the conductive adhesive insulation shielding layer and the aluminum plastic composite belt. The high-voltage rubber jacketed flexible cable for the deicing device provided by the invention is simple in structure and good in shielding effect, and complete shielding coverage is realized; and the electric field charge of a high-voltage cable can be guided and grounded by using the drainage wire which is added into the cable, the surface of the cable and the ground are equipotential, safety operation and cable protection are facilitated, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a high-voltage rubber-sheathed flexible cable, in particular to a high-voltage rubber-sheathed flexible cable specially used for heating and deicing devices for overhead lines. Background technique [0002] In many areas of our country, overhead lines are used for power transmission. In winter when the temperature is low or in rainy and snowy weather, such overhead lines are easy to condense into ice cubes when they are cold. The accumulation of ice cubes increases the load on the overhead wires, causing the overhead wires to be easily broken, resulting in severe power outages. At present, in order to solve the ice on the overhead line, a deicing device for heating the overhead line has been developed, and the device is used to melt the ice on the overhead line. However, overhead lines are usually high-voltage cables. When high-voltage cables are used, induction power plants will be generated on the surface of the cables, and ...

AI Technical Summary

Problems solved by technology

However, overhead lines are usually high-voltage cables. When high-voltage cables are used, induction power plants will be generated on the surface of the cables, and the voltage generated by them will exceed 38V, which will easily cause personal safety hazards, and the discharge point of the high-voltage cable surface to the ground will accelerate the breakdown of the cable. The aging of the insulation and sheath material shortens the service life of the cable, and the cable of the deicing device can only be replaced frequently, and the additional cost is too high
