Self-supporting lightning-proof optical cable

Abstract

The invention discloses a self-supporting lightning-proof optical cable. The self-supporting lightning-proof optical cable comprises a cable core, a covered layer and a suspension wire, wherein the cable core is used for transmitting an optical signal and power; the covered layer is covered with the cable core; and the suspension wire is connected with the covered layer. The covered layer comprises a shielding layer, an outer sheath and a ground layer, wherein the shielding layer shields the cable core; the outer sheath coats the shielding layer; and the ground layer is arranged between the cable core and the shielding layer. The self-supporting lightning-proof optical cable of the invention can prevent communication equipment from being damaged by thunder and lightening, effectively prevent an electromagnetic field generated by the shielding cable from disturbing other communication cable signals and prevent external electromagnetic field from disturbing the cable core.

Description

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

AI Technical Summary

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
