Abstract
The utility model provides a photovoltaic cable comprising conductors, a polyester film winding tape wound round the conductors, 120 DEG C low-smoke zero-halogen flame-retardant irradiated cross-linked polyolefin insulation arranged outside the polyester film winding tape, and a 120 DEG C low-smoke zero-halogen flame-retardant irradiated cross-linked polyolefin sheath arranged outside the 120 DEG C low-smoke zero-halogen flame-retardant irradiated cross-linked polyolefin insulation, wherein the conductors with the pitch thereof being 22 to 25 times are formed by using a continuous-annealing medium wire drawing machine and a continuous-annealing small wire drawing machine to draw oxygen-free electrical round copper rods into round copper wires (phi0.238mm-phi0.375mm) and further using a wire twisting machine to twist the tin-plated round copper wires; and both the 120 DEG C low-smoke zero-halogen flame-retardant irradiated cross-linked polyolefin insulation and the 120 DEG C low-smoke zero-halogen flame-retardant irradiated cross-linked polyolefin sheath are prepared by adding silicone master batches, environment-friendly ultraviolet absorbent, antioxidant and flame-retardant promoter to polyolefin materials. The photovoltaic cable is used for the partial connection between photovoltaic cells and the DC (direct current) terminal of a photovoltaic current converter in a photovoltaic system or the connection between a DC/AC (direct current/alternating current) inverter between terminal boxes and the photovoltaic system.
Description
Technical field
The utility model relates to a kind of cable, refers in particular to a kind of photovoltaic cable that is applied to solar power system.
Background technology
Photovoltaic cable be used for that photovoltaic system connects from photovoltaic cell to part the photovoltaic converter dc terminal or terminal box between DC/AC inverter and photovoltaic system between be connected, it is a significant components of photovoltaic apparatus, as the trunk of solar energy power generating facility electric energy transmitting, be directly connected to fail safe, reliability and the advance of solar photovoltaic generation system.China starts late to the research and development of photovoltaic cable at present, weak foundation, because aspects such as state-of-art, personnel training lag behind, the research and development strength weakness lacks the capability of independent innovation.
Chinese patent once disclosed a kind of " photovoltaic cable " (China, notification number CN201274191Y, July 15 2009 day for announcing), comprised the core that is made of conductor and the outer insulating barrier of conductor, was extruded with the polyolefin external sheath layer outside core; Described insulating barrier is a polyolefin insulation layer.It is simple in structure, and the low smoke halogen-free flame-retardant polyolefin insulating material of its use and sheath material have fabulous heat-resisting, cold-resistant, oil resistant, UV resistant, anti-ozone and weatherability, can use under harsh environmental conditions and under the special use occasion.But also have many improved places that are worth.
The utility model content
The purpose of this utility model is to provide a kind of photovoltaic cable, it has performances such as good low-smoke non-halogen flame-retardant, high temperature resistant, low temperature resistant, acid and alkali-resistance, anti-ozone, environment-friendly type, UV resistant, be used for that photovoltaic system connects from photovoltaic cell to part the photovoltaic converter dc terminal or terminal box between DC/AC inverter and photovoltaic system between be connected.
For achieving the above object, the solution that the utility model is taked is: a kind of photovoltaic cable, it comprises conductor, anaerobic electrician's round copper rod is by the continuous annealing Medium drawing mach ine, little machine drawing is drawn into circular copper wire wrapped polyester film band through zinc-plated zinc-plated round copper wire is twisted into pitch 22-25 conductor doubly by the bunching machine bundle outside of Ф 0.238-0.375mm, the polyester film band is outward by adding silicone master batch in the polyolefine material, the environmental protection ultra-violet absorber, 120 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation polyolefin insulations that antioxidant and fire-retardant promoter are made, 120 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation polyolefin insulations are outward by adding silicone master batch in the polyolefine material, the environmental protection ultra-violet absorber, 120 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation polyolefin jackets that antioxidant and fire-retardant promoter are made.
Insulation and sheath adopt 120 ℃ of low-smoke non-halogen flame-retardant cross-linking radiation polyolefine materials, add silicone master batch in polyolefine material, make cable have the good temperature resistance energy; Add environmental protection ultra-violet absorber and antioxidant, make cable have uvioresistant and stability; Add fire-retardant promoter, make cable have good fire-retardant and resistance to elevated temperatures.
