Abstract
Provided is a high-strength photovoltaic cable. A tinned stranded copper conductor is sequentially coated with an insulating layer, an ethylene-propylene rubber filling layer and an outer sheath. Stainless steel reinforcing ribs are arranged in the ethylene-propylene rubber filling layer. By adopting the insulating layer composed of an irradiation cross-linking low-smoke zero-halogen flame-retardant polyolefin weather-resistant cable material, the thermal properties, mechanical properties and chemical properties of the cable insulation material are improved. The outer sheath composed of a high-tear-resistance silicone rubber compound is weather-resistant and suitable for wild severe environments. Ethylene-propylene rubber has the characteristics of low density and distortion resistance. The stainless steel reinforcing ribs improve the tensile and compressive mechanical properties of the cable.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly relate to the special cable of a kind of solar energy power generating.
Background technology
At present, inexhaustible sun power, the important energy source of China will be become in the middle of this century, the potentiality that solar energy resources develops are very wide, solar cell and module production increase year by year steadily, also there is huge business opportunity as the solar photovoltaic cable connecting photovoltaic module and invertor. But existing solar photovoltaic cable can make cable jacket frangible under severe weather condition, decompose insulation layer, to such an extent as to short-circuit. In order to overcome above-mentioned shortcoming, the solar photovoltaic cable of a new generation adopts two-layer electronic bundle cross-linking radiation insulation layer, the scope of temperature rating is wider, and the spoke process reform chemical structure of polymkeric substance, improve the thermal property of cable, it is to increase the UV resistant irradiation performance of cable, but interior sheath and oversheath all adopt the photovoltaic cable that irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin weather resistant CABLE MATERIALS forms, its cost compare height, weight ratio is heavier.
Summary of the invention
In order to make photovoltaic cable have UV radiation, resistance to decomposition, high temperature resistant better, adapt to outdoor atrocious weather, the present invention provides a kind of high-strength light luff cable, and this high-strength light luff cable has extraordinary tension resistance to compression physical strength, and structure simply easily manufactures.
The technical solution adopted for the present invention to solve the technical problems is: the zinc-plated twisted copper conductors external parcel of high-strength light luff cable forms insulation layer by irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin weather resistant CABLE MATERIALS, it it is ethylene-propylene rubber(EPR) packing layer outside insulation layer, it is provided with stainless steel stiffening web in ethylene-propylene rubber(EPR) packing layer, it is the oversheath of High tear resistance silicon rubber mixture composition outside ethylene-propylene rubber(EPR) packing layer.
The oversheath of High tear resistance silicon rubber mixture composition has weathering resistance and is applicable to field extreme environment; Ethylene-propylene rubber(EPR) has the little and anti-twist characteristic of density; Stainless steel stiffening web improves the tension compressive property of cable; Zinc-plated twisted copper conductors has better snappiness and physical strength than general copper conductor; The insulation layer of irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin weather resistant CABLE MATERIALS composition, improve the thermal characteristic of cable insulation material, mechanical characteristics and chemical property, it is particularly suitable for photovoltaic cable, there is anti-ageingization, ultra-violet radiation resisting, it is to increase the effect of cable intensity.
The present invention useful effect be, the tension resistance to compression ability that its tool is higher, better weathering resistance, wear resistance, flame retardant resistance and high thermal resistance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the present invention.
1. zinc-plated twisted copper conductors, 2. insulation layer, 3. ethylene-propylene rubber(EPR) packing layer, 4. stainless steel stiffening web, 5. oversheath in figure.
Embodiment
In FIG, zinc-plated twisted copper conductors 1 external parcel of high-strength light luff cable forms insulation layer 2 by irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin weather resistant CABLE MATERIALS, insulation layer 2 is outer is ethylene-propylene rubber(EPR) packing layer 3, stainless steel stiffening web 4 it is provided with, the outer oversheath 5 for High tear resistance silicon rubber mixture composition of ethylene-propylene rubber(EPR) packing layer 3 in ethylene-propylene rubber(EPR) packing layer 3.
