Description

A kind of twin-core ultraviolet radiation preventing photovoltaic cable

Technical field

The utility model relates to a kind of cable that have employed special producing technique, particularly relates to a kind of twin-core ultraviolet radiation preventing photovoltaic cable.

Background technology

At present, the industry development of domestic and international new forms of energy photovoltaic generation is rapid, maintain the corollary system normal operation of photovoltaic products mainly by the conversion in the electric flux of photovoltaic effect collection, be transformed into based on solar power generation in electricity generation system, therefore, its each inter-module connecting line cable is the indispensable essential product of transmission total output.Although be exclusively used in stube cable early existing volume production between each matching component, its main performance is confined to originally common low smoke and zero halogen insulated with material plastic product; This low smoke and zero halogen insulated with material plastic product does not possess antiultraviolet, resistance to light radiation, the performance such as ageing-resistant and auxiliary work under being in many special rugged environments for a long time because of it; therefore there is significant drawback in its security performance aspect; general protection effect is not had to the combination property of operating photovoltaic auxiliary products; meanwhile, equipment, instrument, instrument etc. in the work of photovoltaic generation corollary system also can be caused to there is potential safety hazard.

So a kind of photovoltaic accessory cables product demand of extraordinary ultraviolet radiation preventing, low smoke and zero halogen, weatherability and the particular surroundings application that can meet modern photovoltaic generation corollary system is obvious, and Related product technology is badly in need of improving and promoting.

Utility model content

For above-mentioned the deficiencies in the prior art part, the utility model provides one and has ultraviolet radiation preventing, low smoke and zero halogen, oil resistant, wear-resistant, anti-high/low temperature, can bear the superperformances such as larger external force, soft pliable be bent; The twin-core photovoltaic cable of modern photovoltaic generating system Long-Time Service and supporting demand under circumstances can be met.Meet the requirement of modern photovoltaic generating system auxiliary products in many technical fields, and the limitation of original common photovoltaic cable product can be replaced completely, guarantee photovoltaic generating system set of safety.

To achieve these goals, the technical scheme that the utility model adopts is:

A kind of twin-core ultraviolet radiation preventing photovoltaic cable, comprising: the high tenacity outer jointing jacket of resistance to torsion, UV radiation external insulation layer, UV radiation inner insulating layer, zinc-plated soft copper conductor, described photovoltaic cable is four-layer structure.

As preferably, its zinc-plated soft copper conductor adopted first must meet the 5th class zinc-plated soft copper conductor requirement in Europe superscript and national standard " conductor of GB/T3956-2008 cable ", and then through filament tow strand, rear strand twists mode again, guarantees that conductor is closely soft.

As preferably, outside aforesaid zinc-plated soft copper conductor, wrapped one deck have employed the polyolefinic inner insulating layer of (in 110-130 degree Celsius temperature range) low-smoke non-halogen flame-retardant cross-linking radiation that high flexibility ultraviolet radiation preventing screener material is made.

As preferably, in the outside of aforesaid UV radiation inner insulating layer, the polyolefinic external insulation layer of (in 110-130 degree Celsius temperature range) low-smoke non-halogen flame-retardant cross-linking radiation that parcel one deck ultraviolet radiation preventing agent material is made.

As preferably, at the outermost of aforesaid UV radiation external insulation layer, then the low smoke and zero halogen elastomer cross-linking radiation polyolefin outer jointing jacket of the resistance to flexibility of wrapped one deck high strength.

Compared with prior art, the beneficial effect that the utility model brings is:

1, conductor of the present utility model have employed the zinc-plated soft copper conductor of the 5th class meeting national standard, alleviating two old class conductors because of difficulty bends, lays the security implication that stress brings, fully can ensure that cable in use has higher flexible twisting property, ensure the superior functions such as it moves, cloth wire routing is flexible.Simultaneously; the zinc-plated soft copper conductor adopted, its tin coating better can protect current supply line by the corrosion of outer insulating polymeric material, avoids oxidation and becomes fragile and cause short circuit to endanger; make cable conductor more durability, guarantee the durable years that cable operates in tinned conductor and specifies.

2, inside and outside insulating barrier of the present utility model adopts, the polyolefinic insulating barrier of low-smoke non-halogen flame-retardant cross-linking radiation that high flexibility ultraviolet radiation preventing screener material is made.The cable produced is made to have antiultraviolet, low smoke and zero halogen, softness, weather-proof, acid and alkali-resistance, the excellent characteristics such as larger pulling force, bending property is superior, easy to use, the life-span is long can be born; thus substantially prolongs photovoltaic cable physical life; more available protecting photovoltaic system assembly power conversion; avoid trouble free service under the adverse circumstances such as high and low temperature, weather-proof, wind and rain etch, guarantee the safe operation of photovoltaic matching component and inverter.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail:

All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.

See Fig. 1 or Fig. 2, a kind of twin-core ultraviolet radiation preventing photovoltaic cable, comprises zinc-plated soft copper conductor 1, UV radiation inner insulating layer 2, UV radiation external insulation layer 3, the high tenacity outer jointing jacket of resistance to torsion 4.First choose the zinc-plated soft copper conductor 1 meeting national standard " conductor of GB/T 3956-2008 cable " and require, then through the first filament tow strand of special process, then through strand again the form of twisting guarantee that conductor toughness is tight; Then extrude one deck toward zinc-plated soft copper conductor 1 surface and have employed the polyolefinic UV radiation inner insulating layer 2 of (in 110-130 degree Celsius temperature range) low-smoke non-halogen flame-retardant cross-linking radiation that ultraviolet radiation preventing screener material makes; (in 110-130 degree Celsius temperature range) the low-smoke non-halogen flame-retardant cross-linking radiation polyolefinic UV resistant irradiation external insulation layer 3 that one deck anti-ultraviolet radiation agent material makes is extruded again followed by the outside at UV radiation inner insulating layer 2; Finally, in the outside of UV resistant irradiation external insulation layer 3, the more polyolefinic high tenacity of the low smoke and zero halogen elastomer cross-linking radiation outer jointing jacket of resistance to torsion 4 of the resistance to flexibility of wrapped one deck high strength.

In the utility model, described a kind of twin-core ultraviolet radiation preventing photovoltaic cable, its zinc-plated soft copper conductor 1 first monofilament multicore bundle twists, and rear multiple cores twists design again, and stranded employing sub-thread bundle strand twists mode more again, forms the structure of two cores.

In the utility model, described a kind of twin-core ultraviolet radiation preventing photovoltaic cable, have employed first double-deck irradiation technique technique, by the insulating material of vertical structure after accelerator twice cross-linking radiation, the molecular structure of insulating material changes, and becomes closely knit double-deck network structure by original vertical structural change.
