Description
Technical field
The utility model cable technology field relates in particular to the fire-resistant photovoltaic cable of a kind of 1500V low-smoke non-halogen flame-retardant multicore.
Background technology
As everyone knows, the operational environment of photovoltaic generation is quite abominable, expose to wind and rain, expose to the sun and rain, summer is extremely hot, winter cold, acid rain and chemical substance erosion such as saline and alkaline etc., require all parts of photovoltaic generation plate matrix all will adapt to round-the-clock environment, particularly connect the stube cable of photovoltaic generation plate, under above-mentioned mal-condition, need to have the height of anti-the ambient temperature, cold resistance is good, acidproof rain corrodes, the corrosion of alkali resistance material, UV resistant irradiation, fire-resistant, low-smoke non-halogen flame-retardant, resistance to wear is good, bendability height, the characteristic that flexibility is good.Because it is being open-air all that photovoltaic generating system comprises cable, just have following harsh environmental conditions out of doors:
High temperature, ozone and ultraviolet ray irradiation adverse circumstances: the scene temperature of solar power system is up to 100 ℃ when fine day, so high temperature, if cable does not possess resistance to elevated temperatures, cable can't carry out work by galvanization, also has ultraviolet ray and ozone, the environment sunny and light is stronger, its ultraviolet ray and ozone also are very strong, if do not possess the performance of UV resistant and ozone, cable cover(ing) and insulation will be ftractureed under the erosion of sunlight long-term irradiation and ozone, cause cable bad and scrap.
The cryogenic freezing adverse circumstances: photovoltaic generation out of doors, particularly the more place of photovoltaic generation is used in northwest plateau and Europe, its low temperature sometimes can reach subzero more than 40 degrees centigrade, so low temperature, if cable is swung repeatedly under wind action and rubbed, if not having cryogenic property, cable is not easy to ftracture.
Acid rain and saline and alkaline chemical substance corrode adverse circumstances: present environmental pollution is very serious, particularly air pollution, these pollute finally can be taken to big ground by rainwater, and solar power system all is to build the open-air place of not cultivating in, under the rainwater effect, its alkalescence is very big all the year round in these places, and photovoltaic cable sometimes is to lay on the ground, these soda acid chemical substances can be corroded organic material, can conductor insulation and sheath material decomposition.
The fire severe environmental conditions: the possible breaking out of fire in the place of photovoltaic cable process, these will require cable to have low-smoke non-halogen flame-retardant and fire resistance.
If photovoltaic cable does not possess above-mentioned characteristic, it just can't adapt to outwork, says nothing of to have reached useful life more than 25 years.
Photovoltaic cable electric pressure originally has only 0.6/1kV, electric pressure is lower, in order to reach the electricity generation grid-connecting requirement, must carry out parallel connection to improve electric pressure by a plurality of photovoltaic modulies, compare with traditional 1000V DC photovoltaic system voltage assembly, system voltage is that 1500V DC assembly will help the project owner to reduce the power station to be installed in parallel quantity, same system to be installed can to reduce installation system accessory cost, effectively save the cost of operation, maintenance and system balancing.And can't improve the maximum performance of photovoltaic generating system, can't satisfy the more needs of large-scale photovoltaic power station project.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provide a kind of high temperature resistant, anti--40 ℃ of low temperature, acidproof rain corrode, the corrosion of alkali resistance material, UV resistant irradiation and ozone corrode, fire-resistant, low-smoke non-halogen flame-retardant, and resistance to wear is good, the bendability height, the fire-resistant photovoltaic cable of 1500V low-smoke non-halogen flame-retardant multicore that flexibility is good.
The utility model is achieved through the following technical solutions:
The fire-resistant photovoltaic cable of a kind of 1500V low-smoke non-halogen flame-retardant multicore, include the stranded flexible conductor of zinc-plated oxygen-free copper the 6th class, be coated with successively in the outside of the stranded flexible conductor of described zinc-plated oxygen-free copper the 6th class and extrude ceramic silicon rubber flame retardant coating and be that 125 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation insulating barriers of base constitute cores with EVA, three the core outside tangent placements are in twos constituted cable core, be coated with gluing glass fibre belt lapping layer successively in the outside of cable core and be 125 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation restrictive coatings of base with EVA, between described cable core and gluing glass fibre belt lapping layer, be provided with alkali-free glass fibre rope packed layer.
The utility model has the advantages that: the utility model adopts the stranded flexible conductor of zinc-plated oxygen-free copper the 6th class, to improve flexibility and the bending property of cable; Flame retardant coating is to extrude the ceramic silicon elastomeric material, and this material has the refractory temperature height, good insulation preformance, and flexibility is good, performances such as flexibility height; What insulating barrier adopted is to be 125 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation Insulation Material of base with EVA, and this material has environmental protection, low cigarette, Halogen, fire-retardant, high-low temperature resistant, the characteristic of acid-alkali-corrosive-resisting, softness, resistance to wear height, good electric property; Packed layer is filled for the alkali-free glass fibre rope, and this material has the temperature resistant grade height, does not burn performances such as good flame resistance; Twining package tape adopts the gluing glass fibre belt, and this band has good flame resistance, and shelling is good after low cigarette, Halogen, the burning, the effect of heat insulation oxygen barrier; Restrictive coating adopts is to be that 125 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation protective cover materials, these materials of base have long-term high temperature resistant 125 ℃ with EVA, low temperature resistant-40 ℃, UV resistant, wear-resisting wiping, acid and alkali-resistance chemicals burn into UV resistant and macroclimate, low-smoke non-halogen flame-retardant, can stand the characteristics of two 100 tests.
