Low smoke zero halogen waterproof high temperature resistant anti-corrosion armored cable

Abstract

The invention discloses a low smoke zero halogen waterproof high temperature resistant anti-corrosion armored cable which comprises a cable body, insulation wire cores, an insulation layer, a shielding layer and an outer sheath. A plurality of conductors are arranged in the cable body, an insulation wire core is arranged in each conductor, and a PVC plastic connection rod is arranged on the outside of the conductors. A current guide core is arranged at the center position of the cable body, an insulation layer wraps the conductors, a filler is arranged in a gap between the insulation layer and the conductors, a shielding layer is arranged on the outside of the insulation layer, a water-resisting layer and the armored layer wrap the shielding layer from the inside to the outside in an extruding mode, a stainless steel wire weaving layer is arranged on the outside of the armored layer, a heat insulation layer, an inner sheath and an outer sheath wrap the stainless steel wire weaving layer from the inside to the outside, a plurality of ground wire cores arranged in symmetry are evenly arranged in the heat insulation layer, and a graphite layer is arranged between the outer sheath and the inner sheath. The conductors are connected through the PVC plastic connection rod, so that the cable body is stable in use, service performance of the cable body is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of cables, in particular to a low-smoke, halogen-free, waterproof, high-temperature-resistant, corrosion-resistant armored cable. Background technique [0002] At present, with the development of science and technology, high-end fields such as machinery and mining are making rapid progress, which also drives the development of cable and other industries. People have more and more demands for cables. Traditionally, cables only have the effect of conducting electricity. , and cannot withstand higher temperatures. When a fire occurs, these cables not only cannot be fire-resistant and high-temperature resistant, but release harmful gases during the combustion process, which will not only damage the environment, but also cause serious consequences that damage human life and safety. It is often required to be able to be used for a long time, not to be corroded by the harsh environment, to cause damage to the cable, and to b...

[0002] At present, with the development of science and technology, high-end fields such as machinery and mining are making rapid progress, which also drives the development of cable and other industries. People have more and more demands for cables. Traditionally, cables only have the effect of conducting electricity. , and cannot withstand higher temperatures. When a fire occurs, these cables not only cannot be fire-resistant and high-temperature resistant, but release harmful gases during the combustion process, which will not only damage the environment, but also cause serious consequences that damage human life and safety. It is often required to be able to use for a long time, not to be corroded by the harsh environment, causing damage to the cable, and to be able to play the characteristics of waterproof and high temperature resistance, these are the advantages that the existing cables do not have
