Abstract

The invention discloses a self-supporting lightning-proof power cable. The power cable comprises a power transmission cable core, a covering layer for covering the cable core and a suspension wire connected with the covering layer, wherein the covering layer comprises a shielding layer for shielding the cable core, an external tape layer for covering the shielding layer, an external sheath for covering the external tape layer and a grounding layer arranged between the cable core and the shielding layer. The lightning-proof capacity of the power cable is increased by arranging the grounding layer, namely the grounding layer instantaneously conducts the lightning entering the cable into ground to ensure the safety of the power cable and base station equipment connected with the power cable when the lightning strike occurs.

Description

technical field [0001] The invention relates to electric wire and cable technology, in particular to a self-supporting lightning protection power cable capable of lightning protection and suitable for outdoor use. 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. [0003] In...
