Abstract
The utility model provides a polyvinyl chloride (PVC) insulation and sheathed thin steel wire armored fireproof power cable. The structure of the cable is sequentially provided with an insulated fireproof wire core, a filling layer, a wrapping belt, an inside lining, a thin steel wire armored layer and a polyvinyl chloride outer sheath layer from inside to outside. The structure of the insulated fireproof wire core is sequentially provided with conductors, a fireproof mica belt, and a polyvinyl chloride insulation layer from inside to outside. The conductor is wrapped by the fireproof mica belt which is wrapped by the polyvinyl chloride insulation layer. The inside lining is armored with thin steel wire, and the thin steel wire armored layer is formed. A polyvinyl chloride outer sheath is extruded outside the thin steel wire armored layer, and the polyvinyl chloride outer sheath layer is formed. The wrapping belt is a reinforced insulation PVC material winding belt. The conductors are three copper conductors whose cross sections are circles.
Description
Technical field
The utility model relates to a kind of polyethylene insulation and the sheath finer wire is opened the dress power cable, waterproof power cable with cross-linked polyethylene insulation that especially can waterproof.
Background technology
Electric wire is meant the material that is used for electric power, communication and associated transport purposes.Electric wire comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable and optical cable.Flame retardant cable is meant under the condition of regulation test; Sample is burnt; After removing burning things which may cause a fire disaster; Only spreading in limited range of flame, residual flame or residual are burnt in limiting time can become flame retardant cable from the cable of the characteristic of horizontal blanking, and all in other words electric wires through the IEC332 burning test are flame retardant cable.The breaking-up of can burning very soon of common cable insulating barrier after breaking out of fire causes outage, and the pernicious gas that burning produces also can produce injury to the people.
Summary of the invention
The utility model purpose provides a kind of polyvinyl chloride insulation and sheath LWA light wire armoured fireproof power cable; Under the condition of fire; Guarantee that still a period of time inner cable can normal power supply and transmission signals, some important events such as the intensive market of the personnel that are applicable to, skyscraper, subway, industrial and mining enterprises, power station have the ability of fire safety and fire-extinguishing and lifesaving.
In order to address the above problem, the utility model is realized through following technical scheme.
A kind of polyvinyl chloride insulation of the utility model and sheath LWA light wire armoured fireproof power cable comprise the polyvinyl chloride external sheath layer, in the polyvinyl chloride external sheath layer, are provided with the insulated fireproof core successively from inside to outside successively; Packed layer; Band, liner, LWA light wire armoured layer.
The further improvement of the utility model is: insulated fireproof core and packed layer twisting stranding, and the peripheral coiling twining package tape of insulated fireproof core and packed layer, band is wrapped up in liner outward.
The further improvement of the utility model is: at the armoured finer wire of liner, form the LWA light wire armoured layer, outside the wire armoring layer, extrude the polyvinyl chloride oversheath, form the polyvinyl chloride external sheath layer.
The further improvement of the utility model is: fire-resistant core has comprised conductor, fire-resistant isinglass belt, insulating barrier.
The further improvement of the utility model is: insulating barrier, external sheath layer are that pvc material is made.
The further improvement of the utility model is: band adopts the PVC material twining package tape of reinforced insulation, and conductor can have three, and the copper conductor that its cross section is rounded, packed layer adopt glass cord or asbestos cord to fill.
Compared with prior art, the utility model has guaranteed the effective prevention of cable to fire from structure, thereby has improved the cable reliability of operation effectively the useful life of having improved cable.
