Abstract
The invention discloses a flexible fireproof power cable for rated voltage 0.6/1kV. The flexible fireproof power cable comprises conductors. The conductors are covered by an insulating layer and an extruded layer, the extruded layer is covered by an outer sheath which is a threaded copper pipe, and the insulating layer is formed by lapping of multiple layers of mica tapes. As the conductors are covered by the insulating layer which is lapped by the mica tapes and 0.8-2.0 mm in thickness, and then covered by the extruded layer made of ceramic silicon rubber, the conductors are subjected to fireproof protection by the mica tapes and the ceramic silicon rubber, and the fire resistance temperature can be 950-1000 DEG C. As the outer sheath is of the spirally tubular shape, fireproof, waterproof, acid and alkali resistant effects are achieved, while flexibility of the outer sheath is improved, and the flexibility of the overall cable is improved. Gaps among the conductors are filled by polypropylene ropes so that tensile strength of the cable is enhanced while a shielding effect is achieved.
Description
Technical field
The present invention relates to a kind of electric power transfer electric power, be specifically related to a kind of fire resistant flexible power cable for rated voltage 0.6/1kV.
Background technology
In high level and high-rise building, large-scale public place of entertainment, large-scale industrial and mineral, enterprise and underground works thereof, cable cluster laying often, once breaking out of fire, the intensity of a fire will be prolonged along cable place combustion and be spread to other departments or floor, and cable can produce toxic gas in combustion process, and environment and the mankind are caused to secondary injury.Because fireproof cable is the urgent problem solving in current power cable.
Oversheath in power cable, in order to prevent fires, generally adopts the material of fireproof high-temperature resistant, and at present main employing is copper pipe, but because copper pipe material is harder, but manufactures and deposit in process not flexible, is also unfavorable for construction in installation process.
Summary of the invention
The object of this invention is to provide a kind of fire resistant flexible power cable for rated voltage 0.6/1kV, this power cable has good bending property, has good fire protecting performance.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
A fire resistant flexible power cable for rated voltage 0.6/1kV, comprises conductor, and conductor is coated with successively insulating barrier outward and extrudes layer, extrudes layer and is coated with oversheath, and described oversheath is shape of threads copper pipe; Described insulating barrier is that multilayer Mica tape forms.
Further technical scheme: described conductor is single core.
Further technical scheme: described conductor is multicore, is filled with packed layer between the conductor of multicore.
Further technical scheme: described extrudes layer for ceramic silicon rubber.
Further technical scheme: the described thickness that extrudes layer is 1mm～3mm.
Fire resistant flexible power cable for rated voltage 0.6/1kV according to claim 1, is characterized in that: the thickness of described insulating barrier is 0.8mm～2.6mm.
Further technical scheme: described conductor is annealing tin-plating round copper wire.
Further technical scheme: described packed layer adopts polypropylene rope.
The present invention compared with prior art, has following beneficial effect:
(1) conductor of this cable adopts Mica tape to become the insulating barrier of 0.8～2.mm that conductor is coated; then adopt ceramic silicon rubber as extruded layer, conductor to be coated; this cable adopts mica tape and ceramic silicon rubber to carry out flameproof protection to conductor, and refractory temperature can reach 950～1000 ℃.
(2) between the conductor of multicore, adopt polypropylene rope to fill the gap between conductor, rounding is carried out in the gap between conductor, can also strengthen the tensile strength of cable; Also play the effect of shielding, make not interfere with each other between adjacent conductor simultaneously.
(3) oversheath of this cable adopts helical form tubular, not only can play the effect of fire prevention, waterproof, acid-fast alkali-proof, also can increase the flexibility of oversheath, makes the flexible reinforced of whole cable.
