Abstract

The utility model discloses an antiflaming polyolefin sheath power cable. The cable comprises conductors, insulation wire cores and an outer sheath layer. The conductors are coated and pressed by FEP insulation layers. The insulation layers are coated by polyvinyl chloride insulating materials to form insulation wire cores. Two insulation wire cores are stranded and then coated by an antiflaming layer to form a cable core, wherein the antiflaming layer comprises two mica tapes. Four cable cores are integrally coated successively by a polyurethane belting layer, a tin-coated copper filament shielding layer and the polyethylene outer sheath layer. The belting layer is provided with four control wire cores that are formed by conductors coated and pressed by FEP insulation layers. Filling ropes fills the gap among the wire cores and the belting layer. The cable is good in heatproof and low temperature resistant performance, and excellent in antiflaming performance. The antiflaming oxygen index reaches 90. The cable is further excellent in electrical insulating property, water resistance and moisture resistance.

Description

A kind of flame-retardant polyolefin sheathed power cable
Technical field
The utility model relates to a kind of flame-retardant polyolefin sheathed power cable, belongs to technical field of electric wires and cables.
Background technology
Power cable (power cable), for transmitting and distribute the cable of electric energy.Be usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power power, comprising 1-500KV and above various electric pressure, the power cable of various insulation.
Utility model content
It is a kind of simple in structure that the utility model provides, and has the flame-retardant polyolefin sheathed power cable of good electrical insulation properties and resistance to water, moisture-proof.
Scheme of the present utility model is as follows: a kind of flame-retardant polyolefin sheathed power cable, comprise conductor, insulated wire cores and external sheath layer, on conductor, extrude perfluoroethylene-propylene insulating barrier, described insulating barrier is provided with polychloroethylene insulation material composite bed outward and forms insulated wire cores, two fireprotection layer formation cores that the double-deck mica tape of the stranded rear wrapped employing of insulated wire cores forms; Wrapped polyurethane belting layer after four core combinations, the outer wrapped tinned copper wire screen of described belting layer, the outer wrapped outer protective polyethylene jacket layer of described tinned copper wire screen; In described belting layer, arrange four and control core, described control core extrudes perfluoroethylene-propylene insulating barrier outward by conductor and forms; Between described core and belting layer, being provided with gasket for packing fills.
Further, the sectional area of described conductor is 10~240mm 2, described conductor should adopt the 5th kind of annealed copper conductor specifying in GB/T3956.
This practicality has excellent heat-resisting and resistance to low temperature, has splendid fire resistance, and fire-retardant oxygen index is up to 90; Good electrical insulation properties and resistance to water and moisture-proof also simultaneously.For overcoming poly-fluoroplastics material cracking phenomena, insulating barrier extrudes polyvinyl chloride insulation reinforced layer outward; Reached double-insulated usefulness, electric pressure is 600/1000V, finished product test voltage 3500V/5 minute.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of flame-retardant polyolefin sheathed power cable, comprise conductor, insulated wire cores and external sheath layer, on conductor 1, extrude perfluoroethylene-propylene insulating barrier 2, outside described insulating barrier 2, be provided with polychloroethylene insulation material composite bed 3 and form insulated wire cores, two fireprotection layer formation cores that the double-deck mica tape 4 of the stranded rear wrapped employing of insulated wire cores forms; Wrapped polyurethane belting layer 5 after four core combinations, the outer wrapped tinned copper wire screen 6 of described belting layer 5, the outer wrapped outer protective polyethylene jacket layer 7 of described tinned copper wire screen 6; In described belting layer 5, arrange four and control core 8, described control core extrudes perfluoroethylene-propylene insulating barrier outward by conductor and forms; Between described core and belting layer, being provided with gasket for packing fills.
The sectional area of described conductor 1 is 10~240mm 2, described conductor should adopt the 5th kind of annealed copper conductor specifying in GB/T3956.
