Anti-freezing and anti-fracturing power transmission line and manufacturing method thereof

Abstract

The invention relates to an anti-freezing and anti-fracturing power transmission line. The power transmission line comprises a metal wire, a plurality of auxiliary wires, a heat preserving layer and an insulating layer. The auxiliary wires are evenly distributed on the periphery of the metal wire and are circumferentially arranged. A plurality of layers of inclined wires are arranged between every two adjacent auxiliary wires in the wire direction, every two adjacent auxiliary wires are connected through the inclined wires, the inclined wires located on the same layer are distributed in a W-shaped mode, the included angle between each inclined wire and the corresponding auxiliary wire ranges from 30 degrees to 60 degrees, the heat preserving layer wraps the outer layer of the circumference formed by the auxiliary wires, and the insulating layer wraps the outer layer of the heat preserving layer. The anti-freezing performance is greatly improved through the heat preserving layer; due to the fact that the auxiliary wires and the inclined wires are arranged, when the metal wire or one auxiliary wire is fractured, the whole line can be kept in a power-on state due to the connecting function of the inclined wires, and the power-off phenomenon cannot occur; the included angle exists between each inclined wire and the corresponding auxiliary wire, and therefore the whole line can retract conveniently.

Description

technical field [0001] The invention relates to the field of power grid transmission lines, in particular to an anti-freeze and anti-break transmission line and a manufacturing method thereof. Background technique [0002] In the prior art, when the power grid transmission line is used in cold winter, especially after being used for a long time in a cold environment, the inner metal wire is very brittle due to the wire in a frozen state. It is easy to cause the metal wire to break, so that the entire line is powered off, and it takes a lot of time for manual inspection and maintenance, which is time-consuming and labor-intensive. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide an anti-freeze and anti-break transmission line and a manufacturing method thereof. [0004] The present invention is realized in this way, an anti-freezing and anti-breaking power transmission line includes a metal wire, a plurality of auxiliary wires, a thermal insula...

Problems solved by technology

[0002] In the prior art, when the power grid transmission line is used in cold winter, especially after being used for a long time in a cold environment, due to the wire in a frozen state, the internal metal wire is very brittle, and it is very fragile when the wind blows and swings. It is easy to cause the metal wire to break, so that the entire line is cut off, and it takes a lot of time to check and repair manually, which is time-consuming and labor-intensive
