Abstract

The utility model relates to a novel photovoltaic soft cable for connection. The novel photovoltaic soft cable comprises a first cable conductor, a second cable conductor, a first cable insulator, a second cable insulator and a cable sheath layer, wherein the first cable conductor is coated by the first cable insulator; the second cable conductor is coated by the second cable insulator; the first cable insulator and the second cable insulator form a 8-like shape; and the cable sheath layer is coated out of the first cable insulator and the second cable insulator. According to the novel photovoltaic soft cable for connection provided by the utility model, two parallel single-core cables are changed to 8-like two-core parallel cables, materials are saved for 10%, if the material, which is same as 2Pfg-1169:2006, is used to produce, the irradiation cost of the cable is reduced for 20%; the cable sheath layer is made by weather-resistant polyvinyl chloride plastics or irradiated low-smoke halogen-free polyolefin materials, and the price is 40% lower than a PV (Photovoltaic) cable produced by the materials selected according to 2Pfg-1169:2006 standard.

Description

A kind of novel photovoltaic solar connects uses flexible cable

Technical field

The utility model relates to a kind of cable, and the novel photovoltaic solar that especially a kind of cost is low connects uses cable, belongs to the cable technology field.

Background technology

The clean energy resource high speed development of photovoltaic solar energy especially in recent years; Under the support energetically of the Chinese government, the photovoltaic solar production capacity of China is by the starting stage before 10 years, and developing into is that global photovoltaic industry possession share is the highest now; Even face the situation that production capacity is crossed victory; Market price competition is fierce, and the U.S. imposes prohibitive duty to the photovoltaic product of China in addition, makes the photovoltaic solar product of China be difficult to get into American market again.

Therefore, reduce the photovoltaic product cost, making the competition that more adapts to market is the problem of needs solution at present.

Germany TUV company published the 2Pfg-1169:2006 standard in 2006; Stipulated PV (photovoltaic solar cell plate connect flexible cable) technical standard and test stone in the standard, this standard is that German TUV company gets into the technology barriers that European Union market is provided with a high standard, high request for the photovoltaic product.Often a lot of technical conditions are unrealistic; Be that middle home made article is when getting into European Union market especially; Must obtain the TUV authentication; Thereby the TUV certification company obtains the excuse that the great number certification fee is used, and TUV certification company supervision and check expense semiyearly is also very expensive, thereby has increased the production cost of manufacturing enterprise.

And photovoltaic solar cell plate stube cable has adopted the cable of USE-2 and similar structures in the Unite States Standard, and its cable is more suitable than the product of 2Pfg-1169:2006 standard code, and cost is also much lower.

Existing photovoltaic solar connects uses cable, comprises cable conductor, insulating barrier, restrictive coating; Said insulating barrier parcel cable conductor; Said restrictive coating wrap insulate layer; Said restrictive coating is processed by the PV material, the cable of this programme, and cost is high.

The utility model content

The utility model purpose is to have proposed the low novel photovoltaic solar of cost to connect and use cable for the deficiency that overcomes prior art.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel photovoltaic solar connects uses cable, comprises first cable conductor, second cable conductor, first cable insulation, second cable insulation, cable cover(ing) layer; Said first cable insulation wraps up first cable conductor; Said second cable insulation wraps up second cable conductor; Said first cable insulation and second cable insulation form one 8 font; The external packets of said first cable insulation and second cable insulation is wrapped with the cable cover(ing) layer.

Preferably; Said cable cover(ing) layer is processed by weather-proof igelite or irradiation low-smoke halogen-free polyolefin material.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

The described novel photovoltaic solar of the utility model connects uses cable; Single-core cable with two parallel connections is altered to " 8 " font 2 core parallel type cables, can make material economy 10%; Produce the irradiation cost of cable low 20% if adopt with the 2Pfg-1169:2006 identical materials.The cable cover(ing) layer is selected weather-proof igelite or irradiation low-smoke halogen-free polyolefin material for use; The manufacture of materials PV cable low price 40% no matter which kind of material price is selected for use than 2Pfg-1169:2006 standard code, simultaneously cable-20 ℃～+ 105 ℃ service behaviour with suitable with the PV cable of 2Pfg:2006 standard code.

Description of drawings

Below in conjunction with accompanying drawing the utility model technical scheme is described further:

Accompanying drawing 1 connects the sectional view with flexible cable for the novel photovoltaic solar of the utility model;

Wherein: 1, first cable conductor; 2, second cable conductor; 3, first cable insulation; 4, second cable insulation; 5, cable cover(ing) layer.

Embodiment

A kind of novel photovoltaic solar that is depicted as the utility model like accompanying drawing 1 connects uses cable, comprises first cable conductor 1, second cable conductor 2, first cable insulation 3, second cable insulation 4, cable cover(ing) layer 5; Said first cable insulation, 3 parcels, first cable conductor 1; Said second cable insulation, 4 parcels, second cable conductor 2; Said first cable insulation 3 and second cable insulation 4 form one 8 font; The external packets of said first cable insulation 3 and second cable insulation 4 is wrapped with cable cover(ing) layer 5; Said cable cover(ing) layer 5 is processed by weather-proof igelite or irradiation low-smoke halogen-free polyolefin material.

Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
