Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of rated voltage 0.6/1kV flame-retardant power cable.
Background technology
Power cable (power cable) is used to transmit and distribute the cable of electric energy.Be usually used in the underground electrical network in city, 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.
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, coal mining, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.I
There is the cable of special use present stage for some, and its fire resistance also needs further to improve.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provide a kind of fire resistance stronger rated voltage 0.6/1kV flame-retardant power cable.
The utility model is realized through following technical scheme:
Rated voltage 0.6/1kV flame-retardant power cable; Include cable core; It is characterized in that: described cable core includes three cross sections and is circular core conductor, and described three core conductors are isosceles triangle to be arranged, and the outside of every core conductor all is enclosed with fire-resistant mica layer, insulating barrier from inside to outside successively; Three core conductors carry out stranded; The outside of three core conductors after stranded is enclosed with belting layer, inner covering, armour, restrictive coating from the inside to surface successively, and the inboard of described armour is equipped with several drainage threads, and the inboard of insulating barrier is provided with the tension silk; Gap between three core conductors is provided with the filler of band tension silk, and the gap between three core conductors and the belting layer is equipped with filler.
Described insulating barrier adopts crosslinked polyethylene.
The utility model has the advantages that:
The utlity model has fire-resistant mica layer, fire resistance is strong, is equipped with drainage thread in the armour, has formed the full-shield structure, has guaranteed the continuity of screen, and the tension silk has been strengthened the pull resistance of cable.
