Abstract
The utility model discloses a light flame-resistant polrvinyl chloride-insulated and sheathed power cable which comprises three large conductors and a small conductor, wherein the three large conductors and the small conductor are externally and respectively packed with a flame-resistant layer, the flame-resistant layers are formed by packing with a double-layer high temperature-resistant polyester belt in an overlapping way, the packing imbricating ratio is not less than 35%, each flame-resistant layer is externally packed with an insulating layer, the three large conductors which are packed with the insulating layers are distributed outside the small conductor shaped like a Chinese character 'PIN', three cushions which are distributed like a Chinese character 'PIN' are arranged between the small conductor and the insulating layers of the three large conductors to be jointly formed into a cable core, the cushions are formed by the extrusion molding of thermoplastic elastomers, the cushions are internally provided with through holes, and the cable core is externally and sequentially packed with a wrapping layer and a sheathing layer. The light flame-resistant polrvinyl chloride-insulated and sheathed power cable is reasonable in structure design, the flame resistance and fire resistance of the power cable can be effectively improved due to the flame-resistant layers and the high temperature-resistant wrapping layers, and the power cable is further good in extrusion resistance and structure compactness, small in dead weight, and convenient to install and pave.
Description
Technical field:
The utility model relates to the power cable technical field, relates in particular to a kind of light flame-retardant polyvinyl chloride insulation and sheath power cable.
Background technology:
Expansion along with the city, skyscraper, the hotel, large supermarket, hospital, the station, the airport constantly increases, subway, the construction of tunnel traffic, and large-scale Public Physical Education, the public place of entertainment, the increase of public transit facility, the colliery, chemical industry, oil, medicine, military, nuclear power station, iron and steel, metallurgical, the mine, naval vessel etc., fire-fighting, the importance of fire safety shows especially out, how in the situation that fire, ensure within a certain period of time the unobstructed of electric power and communication, win to greatest extent valuable rescue time, reduce personnel's injures and deaths and the safety of lives and properties.
The ac rated voltage that the designer has developed the 3+1 core is the 0.6/1kv power cable, improve the fire resistant flame retardant performance of cable as far as possible, win valuable rescue time to the fire fighter, in addition, improve anti-extrusion performance and the structural compactness of cable, mounting and installation is convenient in the deadweight that reduces cable, prolongs cable useful life.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of light flame-retardant polyvinyl chloride insulation and sheath power cable, reasonable in design has improved the fire resistant flame retardant performance of cable, anti-extrusion performance and structural compactness effectively, has reduced the deadweight of cable.
The technical solution of the utility model is as follows:
Light flame-retardant polyvinyl chloride insulation and sheath power cable, comprise three large conductors, little conductor, it is characterized in that: described three large conductors and little conductor are enclosed with respectively flame retardant coating outward, flame retardant coating adopts overlapping wrapped formation behind the double-deck high temperature resistance polyester band, the wrapped rate of putting up is not less than 35%, flame retardant coating is wrapped with insulating barrier, three large conductors behind the wrap insulate layer are distributed in the outside of little conductor in a triangle, be provided with between the insulating barrier of little conductor and three large conductors and jointly behind the cushion pad that three lobes distribute in a triangle consist of cable core, cushion pad is the thermoplastic elastomer (TPE) extrusion moulding, have through hole in the cushion pad, cable core is enclosed with lapping layer outward successively, restrictive coating.
Described light flame-retardant polyvinyl chloride insulation and sheath power cable is characterized in that: it is flame-proof polyvinyl chloride that described insulating barrier, restrictive coating adopt material.
Described light flame-retardant polyvinyl chloride insulation and sheath power cable is characterized in that: described lapping layer adopts the overlapping wrapped formation of artificial mica synthesis band, and the wrapped rate of putting up is not less than 48%.
The utility model has the advantages that:
The utility model reasonable in design, be provided with flame retardant coating, high temperature resistant lapping layer, fire resistance and the fire resistance of cable have effectively been improved, give under the environment of breaking out of fire and try to gain time precious to one to emergency staffs as far as possible, in addition, cable also has good anti-extrusion performance and structural compactness, conducts oneself with dignity little, is convenient to mounting and installation.
