Description
Technical field
The utility model is related to photovoltaic cable technical field, particularly belongs to a kind of photovoltaic cable.
Background technology
With going deep into that new energy technology is researched and developed, new energy technology is further ripe, and cost also declines to a great extent, consequently also by band
The development of dynamic photovoltaic cable and wind-powered electricity generation cable.
In a broad sense, new energy class cable can just be divided into：Photovoltaic cable, wind electric power generation cable, offshore platform are used
Cable, cable for nuclear power station, electric motor car class cable, inland routine and Unconventional gas exploitation cable etc..With country
New energy development is supported energetically, and enterprisers have smelt business opportunity therein one after another, and increasing cable enterprise is added to development
Among the main forces of new energy cable." vicious circle of cable market has been broken in the appearance of new energy cable, complies with cable market hair
The trend of exhibition, obtains the accreditation and support of cable enterprise.Normal cable is different from, it is competing that new energy cable is increasingly becoming cable enterprise
The focus striven, is increasingly subject to cable enterprise and pursues." New Energy Industry develop rapidly for cable industry development provide wonderful stage.
Because new energy cable scientific and technological content is higher, for the inner cable enterprise of state for concentrating on middle and low-end market, how the epoch are caught
Development trend, complies with the rule of era development, and going into overdrive to develop the new energy cable product accorded with the demands of the market to turn into
The new problem of cable enterprise.
Utility model content
The purpose of this utility model there is provided a kind of photovoltaic cable, overcome the deficiencies in the prior art, in cable outermost
Layer sets the steel ball in the middle of inner restrictive coating, steel ball belt and external sheath layer, double restrictive coatings on clamping steel ball belt, steel ball belt to dash forward
Go out to outside external sheath layer, prominent steel ball constitutes advance ball, can effectively reduce when installation process is pulled and ground
Friction, greatly improves photovoltaic cable physical life and security performance.
To solve the above problems, technical solution adopted in the utility model is as follows：
A kind of photovoltaic cable, including conductor, it is characterised in that：Described conductor is formed into by many tinned copper conductor gluings
Beam is constituted, and outside is enclosed with inner insulating layer, fire-retardant belting layer, proof copper-wire braided screen layer, inner restrictive coating, steel ball belt and outer successively
Restrictive coating, described steel ball belt is formed by steel ball band winding, and described steel ball band includes band body and is uniformly embedded on band body
Steel ball, described steel ball projected to outside external sheath layer.
Further, the strip structure being made up with body of fire-retardant double faced adhesive tape cotton paper.
Further, described steel ball 1/3rd is embedded in internal portion, and 2/3rds project to external side.
Further, described external sheath layer thickness is less than 2/3rds of diameter of the steel ball.
Further, described inner insulating layer, inner restrictive coating use silastic material.
Further, described external sheath layer uses low-smoke halide-free fireproof composite polyolefine material.
Compared with prior art, implementation result of the present utility model is as follows for the utility model：
A kind of photovoltaic cable described in the utility model, inner restrictive coating, steel ball belt and oversheath are set in cable outermost layer
Steel ball in the middle of layer, double restrictive coatings on clamping steel ball belt, steel ball belt is projected to outside external sheath layer, and prominent steel ball, which is constituted, to be slided
Dynamic ball, can effectively reduce the friction on when installation process is pulled and ground, greatly improve the photovoltaic cable practical longevity
Life and security performance.
