Description

A kind of photovoltaic plant flexible fire-proof cable

Technical field

The utility model is specifically related to a kind of photovoltaic plant flexible fire-proof cable.

Background technology

Photovoltaic generating system is the electricity generation system utilizing solar cell directly solar energy to be converted to electric energy, its critical piece is solar cell, storage battery, controller, inverter and cable, be characterized in that reliability is high, long service life, free from environmental pollution, can be incorporated into the power networks again by Independent Power Generation, be subject to the favor of every industry or trade's tissue, there is vast potential for future development.

The cable of photovoltaic generating system is all exposed to field, and field exists the adverse circumstances such as high temperature, ozone, Ultraviolet radiation or cryogenic freezing.Traditional photovoltaic cable has that bending radius is large, difficulty of construction is large, fire resistance rating is low, keep that circuit integrity time is short, not oil resistant, non-refractory, cold-resistant, not UV resistant and ozone and the defect such as useful life is short.When fine day, the scene temperature of solar power system is up to 100 DEG C, and common cable cannot carry out work by galvanization.Sunny and in the environment that light is stronger, its ultraviolet and ozone are also very strong, and cable cover(ing) and insulating barrier will ftracture under the erosion of sunlight long-term irradiation and ozone, cause cable bad and scrap.In the place that northwest plateau and Europe use photovoltaic generation more, its outdoor temperature temperature sometimes can reach subzero 40 DEG C, if cable repeatedly swings under wind action and friction is easy to cracking.

Utility model content

The purpose of this utility model is the shortcoming overcoming prior art, the characteristics such as bending radius is little, high temperature resistant, fire-resistant, cold-resistant, UV resistant, resistance to ozone and long service life that provide one to have, and the photovoltaic plant flexible fire-proof cable that can move place toward backward shift and use.

For achieving the above object, technical solution adopted in the utility model is: provide a kind of photovoltaic plant flexible fire-proof cable, comprise many stranded insulated power cores, insulated power core by some stranded anaerobic tinned copper conductors and the Ceramic silicon rubber insulating barrier that is extruded in outside anaerobic tinned copper conductor, and is coated on the LSOH anti-flaming cross-linking radiation polyolefin protective layer composition outside Ceramic silicon rubber insulating barrier;

Glass twining package tape is surrounded with outside the insulated power core twisted together, glass fiber gasket for packing is filled with between glass twining package tape and insulated power core, Ceramic silicon rubber inner sheath is extruded with outside glass twining package tape, Ceramic silicon rubber inner sheath is coated with the chain armouring of galvanized steel strip, and the chain armouring of galvanized steel strip is coated with LSOH anti-flaming cross-linking radiation polyolefin oversheath.

As preferably, insulated power core has 2 ~ 5.

the beneficial effects of the utility model are:

1, the utility model comprises many stranded insulated power cores, insulated power core by some stranded anaerobic tinned copper conductors and the Ceramic silicon rubber insulating barrier that is extruded in outside anaerobic tinned copper conductor, and is coated on the LSOH anti-flaming cross-linking radiation polyolefin protective layer composition outside Ceramic silicon rubber insulating barrier; Glass twining package tape is surrounded with outside the insulated power core twisted together, glass fiber gasket for packing is filled with between glass twining package tape and insulated power core, Ceramic silicon rubber inner sheath is extruded with outside glass twining package tape, Ceramic silicon rubber inner sheath is coated with the chain armouring of galvanized steel strip, and the chain armouring of galvanized steel strip is coated with LSOH anti-flaming cross-linking radiation polyolefin oversheath.The concrete well oil resistant of this cable, wear-resisting, cold-resistant, high temperature resistant, UV resistant, resistance to ozone, fire resistance rating are high and the characteristic such as long service life, and the little easy construction of bending radius can be used on past backward shift moves place.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.

With reference to figure 1; the present embodiment provides a kind of photovoltaic plant flexible fire-proof cable; comprise many stranded insulated power cores 1; insulated power core 1 is by some stranded anaerobic tinned copper conductors 2 and the Ceramic silicon rubber insulating barrier 3 that is extruded in outside anaerobic tinned copper conductor 2, and the LSOH anti-flaming cross-linking radiation polyolefin protective layer 4 be coated on outside Ceramic silicon rubber insulating barrier 3 forms.

Glass twining package tape 6 is surrounded with outside the insulated power core 1 twisted together, glass fiber gasket for packing 5 is filled with between glass twining package tape 6 and insulated power core 1, Ceramic silicon rubber inner sheath 7 is extruded with outside glass twining package tape 6, Ceramic silicon rubber inner sheath 7 is coated with the chain armouring 8 of galvanized steel strip, and the chain armouring 8 of galvanized steel strip is coated with LSOH anti-flaming cross-linking radiation polyolefin oversheath 9.Insulated power core 1 has 2 ~ 5.

In implementation process; Ceramic silicon rubber insulating barrier 3 is extruded after stranded for some anaerobic tinned copper conductors 2; make insulated power core 1 at Ceramic silicon rubber insulating barrier 3 outer cladding LSOH anti-flaming cross-linking radiation polyolefin protective layer 4, then carry out spark test.

Get four stranded through the insulated power core 1 that spark test is qualified, thoroughly do away with the outer wrapped glass twining package tape 6 of edge power wire core 1 stranded four, and between glass twining package tape 6 and insulated power core 1 filling glass silk gasket for packing 5.Ceramic silicon rubber inner sheath 7 is extruded outside glass twining package tape 6, at the chain armouring 8 of Ceramic silicon rubber inner sheath 7 outer cladding galvanized steel strip, make cable at galvanized steel strip chain armouring 8 outer cladding LSOH anti-flaming cross-linking radiation polyolefin oversheath 9, finally carry out spark test and whether routine test test cable is qualified.
