Self-ice melting cable used for airport

Abstract

The present invention relates to the cable field, in particular to a self-ice melting cable used for an airport. The cable comprises cable cores which are annealing copper conductors, the crosslinkingpolyethylene insulating layers are extruded on the exteriors of the copper conductors, and each copper conductor and each crosslinking polyethylene insulating layer are a cable set. The steel wire ropes used for improving the tensile resistance are braided on the exteriors of the cable sets, a dual-layer metal armored layer is arranged on the exteriors of the steel wire ropes, and a copper wire braided shielding layer is braided on the exterior of the dual-layer metal armored layer. A butyronitrile rubber sheath layer is extruded on the exterior of the copper wire braided shielding layer, anda plurality of heating bodies are all arranged in the stranding center of the cable sets and in the dual-layer metal armored layer and the butyronitrile rubber sheath layer. By utilizing the heatingbodies to heat the cable, not only the cable internal transmission performance stability can be guaranteed, at the same time, the ice on the exterior of the cable can be melted, thereby reducing the influence on the cable transmission.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a self-melting ice cable for airports. Background technique [0002] In the cold winter, due to the low ambient temperature, the transmission performance of the cable will be affected to a certain extent, and the outside of the cable will freeze, which will affect the use. When it is urgently needed, this situation will make the cable unusable, especially At the airport, when the road is icy when flying, it is necessary to use cables to work, causing many people to travel disadvantageously. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a self-melting ice cable for airports. [0004] A self-melting ice cable for airports, comprising a cable core, the cable core is an annealed copper conductor, and the outside of the copper conductor is extruded with a cross-linked polyethylene insulation layer, and the copper conductor an...
