Abstract

The invention discloses a lightning protection power cable, which comprises a power transmission cable core and a coating layer for coating the cable core, wherein the coating layer comprises a shielding layer which shields the cable core, an outer tape layer which coats the shielding layer, an outer sheath which coats the outer tape layer, and a grounding layer which is arranged between the cable core and the shielding layer. In the lightning protection power cable, the grounding layer is arranged to improve the lightning protection capacity of the power cable, namely, the grounding layer conducts thunder and light entering the cable into the ground at the moment when a lightning fire occurs so as to ensure the security of the power cable and base station equipment connected with the power cable.

Description

technical field [0001] The invention relates to electric wire and cable technology, in particular to a lightning protection power cable with a reinforced layer which can prevent lightning and is 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.
