Problems solved by technology

[0002] It is extremely important for the cable to transmit power normally in the case of special changes in the occasions with high requirements for explosion-proof and waterproof performance. Since the intrinsically safe explosion-proof circuit distribution system and automatic detection and control system are used in special occasions, this requires that the cable must have Waterproof, explosion-proof and anti-interference performance, otherwise the failure to meet the use requirements will cause the equipment to malfunction or cause fire and explosion, causing heavy losses to the life and property of the country and the people

Abstract

The invention relates to an underground light-weight lighting cable. The cable comprises a power transmission line core, a signal transmission line core and a control line core. The power transmissionline core comprises a copper conductor and an insulation layer. The signal transmission line core comprises an aluminum conductor and an insulation layer. The control line core comprises a tinned copper conductor and an insulation layer. An insulation filler is arranged among the power transmission line core, the signal transmission line core and the control line core. The power transmission linecore, the signal transmission line core and the control line core are externally wrapped by a copper wire braided shielding layer jointly. The copper wire braided shielding layer is externally provided with an outer sheath. The underground light-weight lighting cable is simple in structure, low in production cost, long in service life, resistant to water, moisture and corrosion, good in mechanical performance, light in weight and convenient to carry.

Description

technical field [0001] The invention relates to a cable, in particular to an underground light lighting cable. Background technique [0002] It is extremely important for the cable to transmit power normally in the case of special changes in the occasions with high requirements for explosion-proof and waterproof performance. Since the intrinsically safe explosion-proof circuit distribution system and automatic detection and control system are used in special occasions, this requires that the cable must have Water-proof, explosion-proof and anti-interference performance, otherwise the failure to meet the use requirements will cause the equipment to malfunction or cause fire and explosion, causing heavy losses to the country and people's lives and property. Contents of the invention [0003] In order to solve the above problems, the present invention provides an underground light lighting cable with simple structure, low production cost, long service life, water and moisture...
