Description
Technical field
The utility model relates to a kind of cable, particularly a kind ofly is applied to the novel low-smoke halogen-free flame retardant photovoltaic cable that solar power generation is used.
Background technology
Along with the enhancing of human environmental consciousness, huge transformation is also taking place in the world energy sources structure, is promptly changed to the sustainable new energy resources system based on regenerative resource by the fossil energy system.Taken temperature by the various regenerative resource resources in the world and China, solar energy is main energy resource, thereby solar power generation should be the main force that extensive electric power will be provided future, is the main direction of extensive development.In recent years, world's photovoltaic cell industry is developed rapidly, and nearly 5 year year increase of production rate reaches 43%, 2004 year whole world total output and reach 1,200,000 kilowatts, and the accumulative total installed capacity reaches 4,330,000 kilowatts.China's photovoltaic cell production capacity in 2004 reaches 100,000 kilowatts, 4.2 ten thousand kilowatts of actual productions, and 6.5 ten thousand kilowatts of accumulative total installed capacitys, the assembly price has also been reduced to 30～40 yuan/kilowatt.Development of technology, good basis has been established in the fast development from now on that drops to of the expansion of industry size and cost.At present, the solar power generation ability 15MW that China has developed will become one of maximum in the world solar energy production state after 2008, possessed the basic condition of large-scale development solar energy.In " National Program for Medium-to Long-term Scientific and Technological Development (2006-2020) ", " high performance-price ratio solar-energy photo-voltaic cell and utilize technology " classified as preferential theme, " the medium-term and long-term development plan of regenerative resource " classifies solar energy power generating as giving priority to field.The market share of China's photovoltaic energy estimates that accounting for 4% from 2003 rose to 2010 20% and the year two thousand twenty 60%.Most of solar energy enterprise is all implementing the photovoltaic generation pattern, and photovoltaic generation is one of fastest-rising industry in the world.And also very wide with the market prospects of photovoltaic cable as the auxiliary products solar power generation of photovoltaic generation, it will constantly enlarge the market use amount along with the development of photovoltaic generation industry.At present, China also is in the starting stage to the research and development as the photovoltaic cable of one of solar energy power generating critical elements, has greatly hindered the fast development of China's photovoltaic generation.
The utility model content
Goal of the invention: the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the novel low-smoke halogen-free flame retardant photovoltaic cable that provides a kind of solar power generation to use.
Technical scheme: the utility model discloses a kind of photovoltaic cable, comprise the core that constitutes by conductor and the outer insulating barrier of conductor, outside core, be extruded with the polyolefin external sheath layer; Described insulating barrier is a polyolefin insulation layer.
In the utility model, preferably, described core is one.
In the utility model, preferably, described core is stranded more than two.
In the utility model, preferably, realize cable fire-retardant in using thereby outside stranded core, be surrounded with fire-retardant belt that glass fiber tape makes.
In the utility model, preferably, described conductive copper or tin-coated copper conductor.
Beneficial effect: the utility model solar power generation photovoltaic cable is simple in structure, polyolefin insulation layer, polyolefin external sheath layer, fire-retardant belt have been added, 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.

Fig. 1 is the cross section structure schematic diagram of single core solar power generation photovoltaic cable of the present utility model.
Fig. 2 is the cross section structure schematic diagram of 4 core solar power generation photovoltaic cables of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Embodiment 1: single core solar power generation photovoltaic cable as shown in Figure 1, and on copper or tin-coated copper conductor 1, extrude low smoke halogen-free flame-retardant polyolefin insulating barrier 2 and constitute single core insulation core, on insulating barrier 2, extrude low smoke halogen-free flame-retardant polyolefin external sheath layer 3.
Embodiment 2: 4 core solar power generation photovoltaic cables as shown in Figure 2, on copper or tin-coated copper conductor 1, extrude low smoke halogen-free flame-retardant polyolefin insulating barrier 2 and constitute single core insulation core, carry out stranded stranding by four cores then and form cable core, a wrapped glass fiber flame retardant belt 4 extrudes low smoke halogen-free flame-retardant polyolefin external sheath layer 3 on fire-retardant belt 4 outside cable core.
The utility model provides a kind of thinking and method of photovoltaic cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
