Abstract
The utility model discloses a photovoltaic cable. The photovoltaic cable comprises a conductor, wherein an insulating layer is extruded on the outer side of a conductor; a metal armouring layer or a metal shielding layer are arranged on the outer side of the insulating layer; and a sheath layer is arranged at the outmost layer of the conductor; and the conductor contains a carbon fiber yarn which is used as a reinforcing structure. By the photovoltaic cable, the conductor which uses the carbon fiber yarn as the reinforcing structure in the photovoltaic cable, the manufactured photovoltaic cable has high tensile intensity; and the photovoltaic cable can be used normally and also can be used under the condition of vertical laying or dragging when needed; and therefore, the equipment and the personal safety can be excellently protected, and the safety service life of the photovoltaic cable can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of improvement to photovoltaic cable.
Background technology
As everyone knows; Heliotechnics will become one of following green energy resource technology, and solar energy or photovoltaic (PV) are used day by day extensive in China, except that the photovoltaic generation factory development rapidly that government supports; The private investor also just actively founds the factory; The sale of solar components will spread all over the world, and build the photovoltaic generation factory of the profitability of economical and efficient, represent all the most important target of solar energy manufacturer and core competitiveness.In fact, profitability not only depends on the efficient or the high-performance of solar components self, also be unable to do without the photovoltaic or the solar energy private cable of electric energy transmitting naturally; The high-quality cable can be avoided maintenance and the maintenance cost of Yin Gaoang and cause solar energy system to get a profit, if but fail to adopt the private cable of Application of Solar Energy, will have influence on the useful life of whole system; And in fact, solar energy system usually can use under severe environmental conditions, except the situation of high temperature and ultraviolet radiation; Also often bear mechanical load, during installation and maintenance, cable can connect up on the sharp edge of roof structure; Cable must bear pressure, bending, tension force, stretched across load and powerful the impact simultaneously; If cable self insufficient strength, then cable will receive badly damagedly, even conductor broken string causes and opens circuit; Thereby influence the safe handling of whole photovoltaic system, perhaps cause the appearance of problems such as short circuit, fire and personnel's risk of injury.
The appearance of carbon fiber is the revolution on the material history; It also is first-selected in the world at present high performance material; Have that high strength, high-modulus, high temperature resistant, corrosion-resistant, endurance, creep resistant, conduction are conducted heat, density is little, light weight, be prone to multiple excellent properties such as processing, belong to typical high-tech product, just progressively conquer and replace traditional material; Be widely used in space flight, aviation and military field already; Countries in the world all have been placed on extremely important position to development high-performance carbon fibre industry, simultaneously more wide space are arranged also in civilian development, and have been deep into the every field of national economy; A kind of special fibre that carbon fiber mainly is made up of carbon is that artificial chemical fibre higher by phosphorus content, not fusion in heat treatment process is processed through technologies such as thermally-stabilised oxidation processes, charing processing and graphitizations, and carbon fiber can be carefully like the spider's thread; Its intensity is more than 62 times of steel; Moulding process is very good, and amount of elasticity and resistance ability be more than 2 times of steel, and proportion is less than 1/4th of steel; It is 1/2nd of aluminium alloy; Therefore and pliability is good, and being widely used in requirement can load-bearing, the strengthening core of the cable of rapid wear inner member not, also has extremely good high-low temperature resistant and corrosion resistance simultaneously.
At present; Consider the destruction of the power such as pulling that photovoltaic cable is born under various conditions; The cable of soft junction structure conductor and small dimension small bore particularly, be easy to lay with use in cause situation such as broken string or drawing-down, the cables manufacturing enterprise that has improves the problems referred to above; Like Chinese utility model patent " solar photovoltaic cable " (publication number 201893159U; Open day on July 6th, 2011) proposed to adopt stainless steel wire braiding reinforced layer to realize protection in to cable, however the just insulating barrier of its protection, when conductor structure is made up of when receiving great pulling force the filament between the 0.10mm to 0.50mm; The fracture of monofilament or whole conductor is that it can't be protected, so also have the improved space of being worth.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of tensile strength high photovoltaic cable.
A kind of photovoltaic cable comprises conductor, and extruded insulation layer successively outside conductor is provided with metal armouring layer or metal screen layer, and outermost layer is provided with restrictive coating, and said conductor is to contain the conductor of carbon fiber wire as reinforcement.
The said carbon fiber wire that contains is that carbon fiber wire and monofilament are twisted together or be incorporated in the conductor as the conductor of reinforcement.
The utility model is used in photovoltaic cable and is contained the conductor of carbon fiber wire as reinforcement; The photovoltaic cable that makes has very high tensile strength; Vertical run or have under the pulling situation uses when needed except that normal use; For equipment and personal safety good protective effect is arranged, prolonged the safe operating life of photovoltaic cable simultaneously greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Like Fig. 1, a kind of photovoltaic cable of the utility model, cable center is a conductor 1, this conductor 1 contains carbon fiber wire as reinforcement.Extruded insulation layer 2 successively outside conductor is provided with metal armouring layer or metal screen layer 3, and outermost layer is provided with restrictive coating 4.
The manufacturing approach of the utility model is: draw carbon fiber wire in advance; The diameter of carbon fiber wire, length and radical are placed carbon fiber wire wherein when strand system or synnema doubling according to the pulling force that carries is complementary, and making becomes the part in the conductor when stranded; Also be combined into an integral body with conductor; Extruded insulation layer outside conductor, insulating barrier outer can wrapped as required metal tape or braiding and dredge around wire as armour or and metal screen layer, extrude restrictive coating then.
Conductor can be selected the 1st kind of conductor among the GB/T 3956-2008, the 2nd kind of conductor, the 5th kind of conductor and the 6th kind of conductor according to laying the characteristics needs of use.
Insulating barrier and restrictive coating can be any material and the compositions that can meet the demands.Metal armouring or screen that insulating barrier is outer, material can be steel band, copper strips, stainless steel wire, copper wire etc., can decide according to the needs of operating position is that armour or metal screen layer are set, wrapped, the braiding of version simultaneously or dredge around etc.
Every do not have substantial change just can reach identical function and effect to the utility model, all belongs to the scope of this patent protection.
Claims (2)
1. a photovoltaic cable comprises conductor (1), extruded insulation layer (2) successively outside conductor; Metal armouring layer or metal screen layer (3) are set; Outermost layer is provided with restrictive coating (4), it is characterized in that, said conductor (1) is to contain the conductor of carbon fiber wire as reinforcement.
