Problems solved by technology

[0002] In the long-term operation of power cables, it is easy to accumulate heat and cause fires. The main factor causing death in fires is not the direct combustion of flames, but the smoke generated when materials are burned. These smokes not only produce a large amount of toxic substances, but also can This is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned, and these are mostly organic polymers, which are easy to burn, so in the event of a fire fueled the fire and caused more damage

Abstract

The invention discloses a polyvinyl-chloride insulation power cable. The polyvinyl-chloride insulation power cable comprises a conductor, a fire-proof mica tape, an insulation layer and a jacket layer. The conductor is externally and sequentially provided with the fire-proof mica tape and insulation wire cores formed by the insulation layer, the multiple insulation wire cores are twisted to be wound around the jacket layer, and gaps between the jacket layer and the insulation wire cores are filled; the insulation layer is prepared from polyvinyl chloride 1, a polystyrene-and-butadiene copolymer, an ethylene-propylene-ethylidene norbornene terpolymer, 6-18 parts of modified opals, modified glass fibers and the like. The polyvinyl-chloride insulation power cable is good in flame retardant performance and high in aging resistance, working stability and reliability; the raw materials of the insulation layer are modified, the insulation layer has the excellent flame retardant performance and the excellent insulating performance, and the whole service life is long.

Description

technical field [0001] The invention relates to a polyvinyl chloride insulated power cable, which belongs to the technical field of electric wires and cables. Background technique [0002] In the long-term operation of power cables, it is easy to accumulate heat and cause fires. The main factor causing death in fires is not the direct combustion of flames, but the smoke generated when materials are burned. These smokes not only produce a large amount of toxic substances, but also can This is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned, and these are mostly organic polymers, which are easy to burn, so in the event of a fire Fueled the fire, causing more damage. Contents of the invention [0003] The object of the present invention is to provide a polyvinyl chloride insulated power cable, which has good flame retardancy, aging resistance, working stability and reliability. ...
