A kind of waterproof and fireproof photovoltaic cable and its compression resistance method

Abstract

The invention relates to the technical field of photovoltaic cables, and discloses a waterproof and fireproof photovoltaic cable and a compression resistance method thereof. The cable comprises thick copper wires, and an outer wall of the thick copper wires is fixedly connected with a plurality of thin copper wires. A wire harness layer is provided on the outside of the wire, an insulating layer is provided on the outer wall of the wire harness layer, a shielding layer is provided on the outer wall of the insulating layer, and a polyethylene waterproof layer is provided on the outer wall of the shielding layer. In the waterproof and fireproof photovoltaic cable, when the mouse bites the surface of the photovoltaic cable, the outermost spring mesh ferrule is made of iron to prevent the mouse from biting. When entering the interior, the waterproof cloth on the inner wall of the stainless steel ferrule has water resistance, which can block water. The unobstructed moisture will be absorbed by the activated carbon powder inward, and then blocked by the polyethylene waterproof layer. Influence, form the effect of anti-moisture, prolong the service life of photovoltaic cables.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a waterproof and fireproof photovoltaic cable and a compression resistance method thereof. Background technique [0002] With the booming of the communication industry, the communication network industry is showing a steady growth trend. Now, when smart devices transmit multimedia data such as audio, video, and video, they are all done through photovoltaic cables. It is a communication cable, which consists of two or more It consists of a glass or plastic optical fiber core, which is located in a protective cladding and covered by a plastic PVC outer sleeve. The bandwidth of optical fiber transmission greatly exceeds that of copper cable, and it supports a maximum connection distance of more than two kilometers. It is an inevitable choice for building a large-scale network. It has the advantages of good electromagnetic interference resistance, strong confidentiality, ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a waterproof and fireproof photovoltaic cable and its anti-pressure method, which has the advantages of anti-mouse bite, high compression resistance and moisture resistance, and solves the problem that the existing photovoltaic cables are easily damaged by mice and Earthquake damage and a large amount of moisture soaking in the air can easily make the internal wire scrapped
