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 lightning-protection optical cable comprising a cable core and a coating layer, wherein the cable core is used for transmitting optical signals and electric power; and the coating layer comprises a shielding layer for shielding the cable core, an outer sheath for covering the shielding layer, and a grounding layer arranged between the cable core and the shielding layer. In the invention, the lightning-protection optical cable can prevent lightning from damaging communication equipment, and effectively shield an electromagnetic field generated by the cable from interfering other communication cable signals and an outer electromagnetic field from interfering the cable.

Description

technical field [0001] The invention relates to wire and cable technology, in particular to a 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 core.
