Abstract
The utility model relates to a photovoltaic cable of 3kV or less. A conductor of multi-strand round copper wires is externally provided with a layer of an irradiation crosslinked polyethylene insulating layer so as to form a wire core. Three wire cores and a flame-retardation mineral matter stretch rope filler form a cable. The flame-retardation mineral matter stretch rope filler is externally provided with a layer of a double-faced aluminium belt, a layer of a polytetrafluoroethylene sealing belt, a layer of a bare copper strip shielding layer and a layer of a silane crosslinked polyolefin sheath layer in sequence. With the adoption of the irradiation crosslinked polyethylene insulating layer and the silane crosslinked polyolefin sheath layer, the cable has excellent performances in heat resistance, low temperature resistance, oil resistance, ultraviolet ray resistance, ozone resistance and weather resistance, can be used under conditions of hostile environments or in some special usage occasions for a long period, and can be normally used in a temperature range of -45 DEG C-110 DEG C. The bare copper strip shielding layer is additionally arranged, so that electrical performances of a product are greatly improved. The photovoltaic cable has excellent electrical performances, a transmission rate is substantially improved, safety factors in an operation process of the product are improved, and the safe operation of an overall system is guaranteed.
Description
Technical field
The utility model relates to a kind of cable, particularly connects a kind of photovoltaic cable of photovoltaic collection plate in outdoor use solar energy photovoltaic system equipment.
Background technology
Solar energy photovoltaic system usually can use under severe environmental conditions, will cause the interior temperature of solar energy system up to 100 ° of C during fine day.At present, we adopt the cables of PVC, rubber, TPE and the making of high-quality cross-linked polymer material more.Also usually use out of doors even rated temperature is the rubber cable of 90 ° of C or PVC cable that rated temperature is 70 ° of C, this will affect the useful life of system greatly.Due to rated temperature restriction, the cracking of cable product, the phenomenon such as aging usually appear, and greatly shortened the useful life of cable.If fail to adopt the private cable of Application of Solar Energy, will have influence on the useful life of whole system.
The deficiency that solar energy dedicated optical luff cable in the market mainly exists is that heat-resisting, resisting ultraviolet radiation, resistance to low temperature are relatively poor, and often product is through after winter, summer alternate run, and aging just more serious, cracking in various degree also appears in restrictive coating.Thereby cause the paralysis of whole system or the damage of miscellaneous part.
Summary of the invention
The utility model main purpose is for the existing above-mentioned technical problem of prior art, provide a kind of heat-resisting good, the resisting ultraviolet radiation effect is good, resistance to low temperature is high, a kind of photovoltaic cable of long service life.
for achieving the above object of the present utility model, the technical scheme that adopts is: a kind of photovoltaic cable, it is characterized in that: the conductor that is included in the soft circular copper wire of multiply is provided with the core that one deck IXPE insulating barrier consists of outward, comprise that also the fire-retardant mineral matter with thermal diffusivity prolongs continuous rope filler, two-sided aluminium strip layer, polytetrafluoroethylraw raw material band, the bare copper strip screen, the silane cross-linked polyolefin restrictive coating, three described cores and fire-retardant mineral matter prolong continuous rope filler stranding together, be provided with successively the two-sided aluminium strip layer of one deck outside it, one deck polytetrafluoroethylraw raw material band, one deck bare copper strip screen, one deck silane cross-linked polyolefin restrictive coating.
The utility model is improved the combination property of the following a kind of photovoltaic cable that uses of 3kV and 3kV by the improvement to the construction of cable, processing method, insulating material.
1, by using IXPE insulating barrier and silane cross-linked polyolefin restrictive coating, make cable have fabulous heat-resisting, low temperature resistant, oil resistant, UV resistant, anti-ozone and weatherability, can use operation under the rugged environment condition or under some Special use occasions over a long time, and can normally use in-45 ℃ ~ 110 ℃ range of temperature.
2, increased the bare copper strip screen, the electric property of product is improved greatly, made it have good electric property, transmission rate has had essential raising, improves the coefficient of safety in the product running, ensures the safe operation of whole system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
as shown in Figure 1, a kind of photovoltaic cable, the conductor 1-1 that is included in the soft circular copper wire of multiply is provided with the core 1 that one deck IXPE insulating barrier 1-2 consists of outward, comprise that also the fire-retardant mineral matter with thermal diffusivity prolongs continuous rope filler 2, two-sided aluminium strip layer 3, polytetrafluoroethylraw raw material band 4, bare copper strip screen 5, silane cross-linked polyolefin restrictive coating 6, three cores 1 and fire-retardant mineral matter prolong continuous rope filler 2 stranding together, be wound around successively the two-sided aluminium strip layer 3 of one deck outside it, wrapped one deck polytetrafluoroethylraw raw material band 4, braiding one deck bare copper strip screen 5, extrude one deck silane cross-linked polyolefin restrictive coating 6.
Two-sided aluminium strip layer 3 width are 15mm, and thickness is 0.2mm.
Bare copper strip screen 5 width are 10mm, and thickness is 0.5mm.
