Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides a kind of compact conformation, fire-resistant effective, not fragile, long service life, the polyvinyl chloride insulation fireproof power cable that conductor diameter range of choice is large.
Technical scheme: in order to solve the problems of the technologies described above, a kind of polyvinyl chloride insulation fireproof power cable of the present invention, it comprises conductor, in described conductor outside, be provided with the first flame retardant coating, in described the first flame retardant coating outside, be provided with insulating barrier, in described insulating barrier outside, be provided with the second flame retardant coating, in described the second flame retardant coating outside, be provided with packed layer, in described packed layer outside, be provided with belting layer, in described belting layer outside, be provided with external sheath layer, the thickness of described insulating barrier is between 1-2.5mm, the thickness of described external sheath layer is between 0.7-3mm, the diameter of described conductor is between 1.78-23.3mm.
Described conductor is for pressing circular stranded conductor or pressing sector conductor, and is at least one.
Described conductor is copper conductor or aluminium conductor.
Described insulating barrier is polyvinyl chloride insulation layer.
Described packed layer is composite material of silicon carbide packed layer.
Described the first flame retardant coating and the second flame retardant coating are all inorganic short fiber viscose glue flame retardant coating.
Described belting layer is polyester belt lapping layer or nonwoven fabrics lapping layer.
