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 arrangement is unreasonable, compact not between layers, conductor shape is more single, packed layer is solid not firmly, filling effect is not good, and thickness of insulating layer arranges inhomogeneous, and thickness does not reach instructions for use, insulation effect is undesirable, conductor diameter range of choice is little, and interior external sheath layer is fragile, and whole service life is shorter.
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, and interior external sheath layer is set, not fragile, long service life, the inside and outside sheath power cable of polyvinyl chloride insulation wire armoring that conductor diameter range of choice is large.
Technical scheme: in order to solve the problems of the technologies described above, the inside and outside sheath power cable of a kind of polyvinyl chloride insulation wire armoring of the present invention, it comprises conductor, in described conductor outside, be provided with insulating barrier, in described insulating barrier outside, be provided with packed layer, in described packed layer outside, be provided with inner restrictive coating, in described inner restrictive coating outside, be provided with wire armoring layer, in described wire armoring layer outside, be provided with external sheath layer, the thickness of described insulating barrier is between 1-2.6mm, the thickness of described inner restrictive coating is between 1.5-2.8mm, the thickness of described external sheath layer is between 1.8-3.2mm, the diameter of described conductor is between 4.1-19.2mm.
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 inner restrictive coating is polyvinyl chloride or pe sheath layer.
Described external sheath layer is polyvinyl chloride or polyethylene or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
When conductor of the present invention is one, do not need to use packed layer.
Conductor of the present invention can all be used 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, for meeting different instructions for uses.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: compact overall structure of the present invention, between each layer, be connected, reliable, adopt the insulating barrier between 1-2.6mm, can effectively guarantee insulation effect, adopt the inner restrictive coating of 1.5-2.8mm and the external sheath layer between 1.8-3.2mm, can play double protection, can guarantee that cable outside is more solid firmly, not fragile, adopt composite material of silicon carbide packed layer, can effectively improve filling effect, adopt polyester belt lapping layer, play good package action, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve cable result of use, integral product is longer useful life, realistic instructions for use.
