Problems solved by technology

[0002] At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements for cables are also continuously improving, such as cables used in industries, electric power and coal mines, etc. The requirements are particularly high. The traditional cables are not well adapted to these relatively harsh environments due to materials and other reasons. Long-term use of such cables will affect the work, efficiency and safety in these fields, so people need a A safe, reliable and oxidation-resistant cable

Abstract

The invention discloses an inflaming-retarding anti-oxidization high-voltage-resistant power cable which is composed of conductors, a ceramic fluoro-rubber insulating layer, a copper clad steel shielding layer and an outer sheath. The conductors are wrapped by the ceramic fluoro-rubber insulating layer; two or more cable cores are arranged in each conductor; the conductors are connected through PP plastic connecting rods; four grounding wire cores are tangent to the PP plastic connecting rods; filler is arranged in the gap part between the conductors and the ceramic fluoro-rubber insulating layer; the ceramic fluoro-rubber insulating layer is wrapped by the copper clad steel shielding layer; the copper clad steel shielding layer is formed by tightly arranging the outer sheath, a tined copper wire braided layer and a highly-inflaming-retarding fiber lapped layer from outside to inside in an extruded mode. Thus, the inflaming-retarding anti-oxidization high-voltage-resistant power cable has good shielding performance, anti-oxidization performance and high electric conductivity, and further has high-voltage resistance and magnetic interference resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant, oxidation-resistant and high-voltage resistant power cable. Background technique [0002] At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements for cables are also continuously improving, such as cables used in industries, electric power and coal mines, etc. The requirements are particularly high. The traditional cables are not well adapted to these relatively harsh environments due to materials and other reasons. Long-term use of such cables will affect the work, efficiency and safety in these fields, so people need a A safe, reliable and oxidation-resistant cable. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a flame-retardant, oxidation-resistant and high-voltage resistant power ...
