Abstract

The invention discloses a cable for solar power generation. The cable is characterized in that the outer sides of conductors are wrapped with high-temperature-resistant fluoroplastic insulating layers respectively for forming wire cores, after being wrapped with insulating layers, every two wire cores are stranded and bundled, an anti-flaming oxygen isolating wrapping tape overlapped wrapped wrapping layer is arranged outside every two bundled wire cores, a shielding layer is arranged outside each wrapping layer for forming a wire core group, a wrapping layer II is wrapped after three wire core groups are combined, an inner lining layer is arranged outside the wrapping layer, an armoring layer is arranged outside the inner lining layer, a sheathing layer is wrapped outside the armoring layer, anti-flaming glass fiber ropes are filled between the wrapping layer II and the wire core group, and three nylon ropes are arranged among the three wire core groups. The armoring layer adopts a galvanized steel strip which has good mechanical protection performance; the fluoroplastic F46 materials having excellent high temperature resistance are adopted as the insulating layers; the three nylon ropes are arranged among the three wire core groups, so that the anti-twisting performance of the cable is effectively improved.

Description

A kind of solar power generation cable

technical field

The present invention relates to cable industry, be specifically related to a kind of solar power generation cable.

background technology

Under the trend that photovoltaic industry is accelerated to start at home, the photovoltaic whole industry or reproduction higher speed increase.Electric wire industry

Inner analysis personage think, along with progressively open and the further reinforcement of policy support in photovoltaic market, roof, builds roof light

Overhead utility, promotes middle-size and small-size photovoltaic system application, by becoming gradually the main flow of industry development, will promote solar cables

Grow up in market, solar power generation is also had higher requirement with cable.

summary of the invention

The object of this invention is to provide a kind of solar power generation cable, met light-duty, heat-resisting that solar electricity generation field cable used has, the performance index such as fire-retardant have also solved the problems such as volume is large, ampacity is little simultaneously.

The solution of the present invention is as follows: a kind of solar power generation cable, comprise conductor, insulating barrier, described conductor outside is enclosed with respectively thermostable fluorine plastic insulating layer and forms core, two stranded bunchys of core after wrap insulate layer, after bunchy, arranged outside has the overlapping wrapped belting layer of fire-retardant oxygen barrier band, described belting layer arranges tinned copper wire screen outward and forms core group, wrapped belting layer II after three core combinations, described belting layer II arranges the inner covering that extrudes formation with the anti-ozone polyolefin of high flame resistance, low smoke Halogen antiultraviolet outward, described inner covering arranges two wrapped armours of steel band outward, described armour outside is enclosed with the anti-ozone polyolefin jacket of high flame resistance, low smoke Halogen antiultraviolet layer, between described belting layer II and core group, be filled with flame retardant type glass cord, between three described core groups, be also provided with three nylon ropes.

Further, described belting layer and belting layer II adopt the overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band.

Armour of the present invention adopts galvanized steel strip, has good mechanical protection performance, with fluoroplastics F46 material be insulation, there is good resistance to elevated temperatures; Cable cover(ing) adopts low smoke and zero halogen antiultraviolet anti-ozone polyolefine material, has the performances such as withstand voltage, heatproof, is also provided with three nylon ropes between three core groups, has doing to turn round and drawing performance of the raising cable that can imitate.

brief description of the drawings

Fig. 1 is structural representation of the present invention.

embodiment

Below in conjunction with accompanying drawing, the present invention will be further described.

A kind of solar power generation cable, comprise conductor 1, insulating barrier 2, described conductor 1 outside is enclosed with respectively thermostable fluorine plastic insulating layer 2 and forms core, the rear two stranded bunchys of core of wrap insulate layer 2, after bunchy, arranged outside has the overlapping wrapped belting layer 3 of fire-retardant oxygen barrier band, the outer tinned copper wire screen 4 that arranges of described belting layer 3 forms core group, wrapped belting layer II 5 after three core combinations, the outer inner covering 6 that extrudes formation with the anti-ozone polyolefin of high flame resistance, low smoke Halogen antiultraviolet that arranges of described belting layer II 5, the outer pair wrapped armours 7 of steel band that arrange of described inner covering 6, described armour 7 outsides are enclosed with the anti-ozone polyolefin jacket of high flame resistance, low smoke Halogen antiultraviolet layer 8, between described belting layer II 5 and core group, be filled with flame retardant type glass cord, between three described core groups, be also provided with three nylon ropes 9.

Described belting layer 3 and the belting layer II 5 overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band that adopts.

Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
