Problems solved by technology

[0002] The single-core wire in the traditional prior art will age rapidly with the service life, and it is easy to damage the internal structure, causing the internal core wire to break, and the cable is due to the harsh environment of wind power generation, the fan has a long service life, and the cable With the continuous rotation of the fan, the performance requirements of the cable are relatively high, and there are still many difficulties to be overcome in the development and application of wind energy cables
It is not durable, not strong, and the anti-corrosion effect is not good, especially the poor flame-retardant effect is a serious problem

Abstract

The invention provides a flame-retardant and waterproof power line, which comprises a metal conductor (1) as an innermost layer, wherein an insulated durable protection layer (2) surrounds the outside of the metal conductor (1); a polyvinyl chloride layer (3) surrounds the outside of the insulated durable protection layer (2); a braid layer (4) is arranged outside the polyvinyl chloride layer (3); a halogen-free flame-retardant TPEE material layer (5) is arranged outside the braid layer (4); mixed powder of flame retardants Sb2O3 and Mg(OH)2 is evenly added to the inside of the insulated durable protection layer (2); and the mass ratio of the flame retardant Sb2O3 to the flame retardant Mg(OH)2 is 3 to (5-9). The flame-retardant and waterproof power line has the advantages of high insulating property and good antiseptic property; and most importantly, the water-proof capability, the flame-retardant property and the like are relatively greatly improved.

Description

technical field [0001] The invention relates to the technical field of power cords and cables, in particular to a flame-retardant and waterproof power cord. Background technique [0002] The single-core wire in the traditional prior art will age rapidly with the service life, and it is easy to damage the internal structure, causing the internal core wire to break, and the cable is due to the harsh environment of wind power generation, the fan has a long service life, and the cable With the continuous rotation of the fan, the performance requirements of the cable are relatively high. There are still many difficulties to be overcome in the development and application of wind energy cables. It is not durable, not strong, and the anti-corrosion effect is not good, especially the problem of poor flame-retardant effect is serious. Contents of the invention [0003] The purpose of the present invention is to provide a flame-retardant and waterproof power cord, which has high ins...
