Abstract
The utility model discloses a polyvinyl chloride insulating multi-core power cable. The power cable comprises a cable core, a filling layer is arranged in gaps of the cable core, a lining layer is extruded outside the cable core, an armor layer is woven outside the lining layer, an outer sheath is extruded at the outmost layer of the cable core, and each cable core is formed by stranding three fan-shaped insulating wire cores and one circular insulating wire cores. The polyvinyl chloride insulating multi-core power cable is stable in structure, strong in reliability, good in fire resistance, long in service life and suitable for places with high laying density, such as power stations, metros, tunnels, high-rise buildings, large-scale industrial and mining enterprises, oil fields and coal mines.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of polyvinyl chloride insulation multi-core power cable.
Background technology
Power cable be divided into some kinds by principal characters such as its scope of application, design feature and performance requirements, PVC insulated power cable is wherein a kind of.PVC insulated power cable, in indoor, the tunnel of mainly being laid in and in pipeline, but also buried-pipe laying.Existing common PVC insulated power cable, there is the poor and incendive problem of structural stability, this has increased certain difficulty to the design of PVC insulated power cable, therefore the lsafety level of electric wiring and the fire-retardant problem of cable more and more cause people's concern, and fire-retardantization of cable become a comprehensive developing direction of cable industry.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of structural stability, reliability is strong, good flame resistance, the polyvinyl chloride insulation multi-core power cable of long service life.
A kind of polyvinyl chloride insulation multi-core power cable described in the utility model, comprise cable core, in the gap of cable core, is provided with packed layer, and cable core extrudes inner covering outward, and inner covering weaves armour outward, and the cable core outermost layer extrudes oversheath; Described cable core is by three fan-shaped insulated wire cores and stranded forming of round insulation core.
Further improve, described fan-shaped insulated wire cores is identical with round insulation core structure, by conductor and be coated on the conductor external insulation layer and form.
Further improve, described armour is braided steel wire structure or steel band structure again.
The beneficial effects of the utility model are:
Compared with prior art, the structure that the utility model cable adopts, improved aging phenomenon, job stability and the reliability of polyvinyl chloride cable have been improved, when cable is on fire, the carburization zone that inner covering, oversheath form heat insulation resistance oxygen plays protection to cable, thereby stops flame cable expansion burning; The wire armoring structure has also improved the shielding of cable in addition, thereby has improved the useful life of cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of polyvinyl chloride insulation multi-core power cable described in the utility model, comprise cable core, in the gap of cable core, is provided with packed layer 3, and cable core extrudes inner covering 4 outward, the outer braiding armour 5 of inner covering 4, and the cable core outermost layer extrudes oversheath 6; Described cable core is by three fan-shaped insulated wire cores and stranded forming of round insulation core.Described fan-shaped insulated wire cores is identical with round insulation core structure, by conductor 1 and be coated on conductor 1 external insulation layer 2 and form.
Armour 5 described above is braided steel wire structure or steel band structure.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
