High-temperature-resisting coaxial cable used for underworkings

Abstract

The invention discloses a high-temperature-resisting coaxial cable used for underworkings. The high-temperature-resisting coaxial cable comprises a coaxial cable core, a nickel plated copper braid shielding layer, an insulating layer and a sheath, wherein the coaxial cable core is composed of a center conductor, an armor layer and an outer conductor, a high-temperature-resisting layer is arranged between the insulating layer and the sheath and formed by tightly arraying a plurality of high-temperature-resisting strips in an externally tangent mode, a drainage wire is wrapped by the insulating layer, and the sheath is a fluorescent sheath. The cable is good in electric conductivity, resistant to dragging, breaking, and moisture, waterproof, low in smoke, free of halogen, environmentally friendly, resistant to high temperature, oil and acid, weatherproof and high in shielding performance, damage to the human body and the ambient environment is small, and the cable is mainly applied to the underworkings, can emit fluorescence in a dark environment and is convenient to lay and repair.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a high-temperature-resistant coaxial cable for underground roadways. Background technique [0002] At present, with the development of society and economy, the consumption of cables is increasing rapidly, and the quality requirements for cables are also constantly improving. For example, in the mining work of coal mines, due to the dark underground roadway, ordinary cables are almost invisible or unclear, which makes the installation and maintenance of cables inconvenient, and there is a great hidden danger to safe mining. Another example is that ordinary cables mostly use PVC sheaths, which have insufficient high temperature resistance. Once the cables burn, they will release a large amount of dense smoke and toxic gases, which will affect rescue. Only by meeting the various requirements of the cable can the safe use of the cable be better guaranteed. Contents of the invention [0...
