At present, the cable on market is various, and they are applied in various different occasions.But all there are some problems in most of cable, such as layer of structure arranges unreasonable, compact not between layers, conductor shape is more single, packed layer is solid not, and firmly filling effect is not good, and thickness of insulating layer arranges inhomogeneous, thickness does not reach instructions for use, insulation effect is undesirable, and the conductor diameter range of choice is little, the fire-resistant poor effect of flame retardant coating, external sheath layer is fragile, and whole service life is shorter.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of compact conformation is provided, and is fire-resistant effective, not fragile, long service life, the polyvinyl chloride insulation fireproof power cable that the 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 described in the utility model, it comprises conductor, be provided with the first flame retardant coating in described conductor outside, be provided with insulating barrier in described the first flame retardant coating outside, be provided with the second flame retardant coating in described insulating barrier outside, be provided with packed layer in described the second flame retardant coating outside, be provided with belting layer in described packed layer outside, be provided with external sheath layer in described belting layer outside, 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 the polyvinyl chloride insulation layer.
Described packed layer is the 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.
Described external sheath layer is polyvinyl chloride or polyethylene or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
When conductor described in the utility model is one, do not need to use packed layer.
Conductor described in the utility model can all use and press circular stranded conductor, also can all use and press sector conductor, can also press circular stranded conductor and press sector conductor to be used in conjunction with, and is used for meeting different instructions for uses.
beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model compact overall structure, be connected between each layer, reliable, adopt the insulating barrier between 1-2.5mm, can effectively guarantee insulation effect, adopt the external sheath layer between 0.7-3mm, can guarantee that the cable outside is more solid firmly, not fragile, adopt the conductor of diameter between 1.78-23.3mm, the scope that can select is wider, in order to meet different instructions for uses, adopt the composite material of silicon carbide packed layer, can effectively improve filling effect, the first flame retardant coating and the second flame retardant coating adopt inorganic short fiber viscose glue, fire-resistant effective, adopt the polyester belt lapping layer, play good package action, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve the cable result of use, integral product is longer useful life, realistic instructions for use.
