Description
Technical field
The utility model relates to the photovoltaic cable technical field, specifically, has related to a kind of low-smoke non-halogen flame-retardant photovoltaic cable.
Background technology
Under the impact of financial crisis, the Chinese government is developing new forms of energy as the important means of revitalizing the economy.Heliotechnics will become one of following green energy resource technology undoubtedly, solar energy or photovoltaic (PV) are day by day extensive in China's application, build the photovoltaic generation factory of the profitability of economical and efficient, the most important target of all solar energy manufacturers and core competitiveness have been represented, and its profitability not only depends on efficiency or the high-performance of solar components self, also be unable to do without its important transmission of electricity instrument--photovoltaic cable, but photovoltaic generation factory is built in desert belt mostly, environment is extremely disliked slightly, and existing photovoltaic cable, under this environment, its weather resistance, UV resistant, it is barely satisfactory that anti-ozone corrosion and the larger abilities such as variations in temperature of opposing still show, photovoltaic generation factory needs the frequent cable of changing to guarantee the efficient stable of self, greatly increased production cost, also caused larger environmental pollution simultaneously.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
The utility model content
The purpose of this utility model is a kind of low-smoke non-halogen flame-retardant photovoltaic cable, with solve that existing photovoltaic cable exists to ultraviolet ray, ozone corrosion and the low problem of larger variations in temperature tolerance.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of low-smoke non-halogen flame-retardant photovoltaic cable comprises by the many stranded conductor wire cores that form of tin-coated copper monofilament, the overlapping wrapped separator consisted of low-smoke non-halogen flame-retardant glass strap outside described conductor wire core, extrudes the insulating barrier outside described separator and extrude the restrictive coating outside described insulating barrier.
Base the above, the outermost lay ratio of described conductor wire core is 9, the lay ratio of described each layer of conductor wire core adds 2 successively according to order from outside to inside.
Base the above, described insulating barrier consists of 150 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin material.
Base the above, described restrictive coating consists of 150 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin material.
Base the above, the overlapping width of overlapping wrapped low-smoke non-halogen flame-retardant glass strap outside described conductor wire core is its bandwidth 15%～25%.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, 1. in the utility model, the conductor wire core of low-smoke non-halogen flame-retardant photovoltaic cable forms by many tin-coated copper monofilament are stranded, the structure that more common strand twists again adapts to more dislikes weather conditions slightly, and more lengthen useful life, 2. add successively from outside to inside 2 rule bundle strand conductor wire core according to lay ratio, this Stability Analysis of Structures, flexible, outward appearance is Paint Gloss, 3. solar energy system usually can be used under severe environmental conditions, the material of outdoor use should be according to ultraviolet ray, ozone, violent variations in temperature and chemical erosion situation and determine, use low-grade material under this kind of environmental stress, to cause cable cover(ing) frangible, even can decompose cable insulation, all these situations all can directly increase the cable system loss, the risk that cable short circuit occurs simultaneously also can increase, in a midium or long term, the possibility of breaking out of fire or personnel's injury is also higher, and low smoke halogen-free flame-retardant polyolefin is as insulating barrier and restrictive coating, obviously do not reach the specification requirement of photovoltaic cable, the anti-environment capacity of product is strengthened, long service life, just must carry out crosslinked thermoplastic olefin material being converted into to the thermosetting polyolefine material, and general crosslinking method is difficult to make material to meet the requirements of technical indicator, only has the electron irradiation of selection crosslinking method, after electron irradiation, changed the chemical constitution of polymer, the meltability thermoplastic material is converted to non-meltability elastomeric material, cross-linked radiation has significantly improved the thermal characteristic of cable insulation material, mechanical property and chemical characteristic, make it for ultraviolet ray, ozone corrosion and the large temperature difference have good tolerance, 4. it is overlapping wrapped that described separator adopts low-smoke non-halogen flame-retardant glass strap, and overlapping width is its bandwidth 15%～25%, this kind of material has the characteristic of high flame retardant, during high, the passive burning of intensity, be fuming few, wrappedly like this can make its largeizationr of effect, useful life is also longer, its have advantages of design science, environment friendly and pollution-free, more weather resistance, more UV resistant, more anti-ozone burn into can bear wider variations in temperature.
