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 wire and cable technology, in particular to a lightning-proof power cable with a reinforced layer that can protect against lightning and is suitable for outdoor use. Background technique [0002] Base station construction sites are mostly open, highlands or mountainous areas, with complex terrain and harsh working conditions. The equipment of the base station is easily damaged by thunder and lightning. The outdoor cables of the base station are especially low in winter and are directly exposed to ultraviolet rays in northern areas. Aging and damage, thereby affecting the operation of the base station. The cable used as a communication base station should have a certain degree of shielding and anti-interference to ensure that its own electromagnetic field does not cause interference to other signals and is not interfered by external electromagnetic fields on the cable core. [0003] In addition, since the cable may be struck by lightn...
