Liquid cable

Abstract

The invention provides a liquid cable, which comprises: an elastic sealing pipe of which the end part is provided with a wiring terminal; a plurality of insulators sequentially arranged in a pipe cavity of the elastic sealing pipe at intervals and dividing the pipe cavity of the elastic sealing pipe into a plurality of sub-pipe cavities; a conductive liquid, wherein the elastic sealing pipe is filled with the conductive liquid, and the conductive liquid expands the elastic sealing pipe, so that a gap is formed between the inner wall of the elastic sealing pipe and an insulator, and the adjacent sub-pipe cavities are communicated. Under the condition that the elastic sealing pipe leaks, the elastic sealing pipe contracts and is attached to the insulator so as to cut off the adjacent sub-pipe cavities. According to the invention, under the condition that the liquid cable leaks, a communication path of the conductive liquid in the adjacent sub-tube cavities can be cut off, then the conductive path is cut off, and safety accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a liquid cable. Background technique [0002] Usually, the cable is composed of several wires or groups of wires. Each group of wires is a rope-like structure twisted by at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer The bread has a highly insulating covering layer, which is used for the transmission of strong electric energy in the transmission, distribution, transmission, transformation and power supply lines. [0003] In addition, when the cable breaks and the insulation layer falls off, some cables still have the conductive function, which poses a safety hazard, which leads to safety accidents in practical applications and causes heavy losses to people's lives and property. [0004] At present, the liquid cables with the basic functions of cables sold on the market are very dangerous when the wires a...

[0003] In addition, when the cable breaks and the insulation layer falls off, some cables still have a conductive function, which poses a safety hazard, which leads to safety accidents in practical applications and causes heavy losses to people's lives and property

[0004] At present, the liquid cables with the basic functions of cables sold on the market are very dangerous when the wires are broken and the conductive liquid leaks without protective measures.

In actual use, the breakage of the liquid cable and the damage of the insulating layer are inevitable. The terminals at both ends of the liquid cable are still connected to the conductive liquid, which is easy to cause leakage and poses a major safety hazard.
