Problems solved by technology

[0003] In addition, because the cable may be struck by lightning, once a lightning strike occurs, it will cause serious losses to communication facilities
[0004] In addition, at present, communication base stations need to use electric cables and optical cables to transmit power and communication signals, which is not only troublesome to lay, but also increases the cost of cables used by communication base stations

Abstract

The invention discloses a multigroup lightning protection optical cable which comprises cables and a coating layer covering the cables, wherein the cables are made of multigroup cable cores covered by an inside liner; and the coating layer comprises a shielding layer for shielding the cables, an outer jacket covering the shielding layer and a grounding layer arranged between the inside liner and the shielding layer. The multigroup lightning protection optical cable can prevent lightning from damaging communication equipment, and can effectively shield the interference of an electric magnetic field generated by the cables on other communication cable signals and the interference of an external magnetic field on the cables.

Description

technical field [0001] The invention relates to wire and cable technology, in particular to a multi-group lightning protection optical cable capable of lightning protection and transmission of optical signals and electric power. Background technique [0002] Based on the base station construction sites are mostly open, highland or mountainous area, the terrain is complex and the working environment is harsh, the equipment of the base station is easily damaged by lightning weather, the outdoor cables of the base station, especially in the northern area where the temperature is low in winter and directly exposed to ultraviolet rays, are prone to damage. Aging and damage will affect the work of the base station. The cable used as a communication base station should have certain shielding and anti-interference performance to ensure that its own electromagnetic field does not interfere with other signals and is not interfered by the external electromagnetic field on the cable cor...
