Abstract
The utility model provides a flat twin-core photovoltaic cable which comprises two transmission core wires. The two transmission core wires are arranged in parallel, insulating covers are wrapped on outer sides of the transmission core wires, sheaths are wrapped on outer sides of the insulating covers, and a connecting portion is connected between the sheaths of the two transmission core wires. 56 wires are twisted to form each transmission core wire. The connecting portion is bumpy, two ends of the connecting portion are thick, and the middle of the connecting portion is thin. By the aid of the flat twin-core photovoltaic cable, electric energies of two solar cell panels can be simultaneously transmitted, effective electric energy conversion rate is high, and the flat twin-core photovoltaic cable is installed conveniently.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of flat twin-core photovoltaic cable.
Background technology
Most in the market photovoltaic cable all is according to Germany and Unite States Standard application authentication and the photovoltaic cable produced; The photovoltaic cable of these two standards all is single core double-layer insulating structure; Double-insulated material is cross-linked polyolefin (XLPO) material, specified alternating voltage 600/1000V, direct voltage 1800V, rated temperature :-40 ℃ to 120 ℃; Be used to connect photovoltaic terminal box cell panel, in order to electric energy transmitting.The defective that photovoltaic cable exists in the prior art is: 1, photovoltaic cable is single core double-layer insulating structure; A single cored structure photovoltaic cable can only connect a photovoltaic junction box; Can not in a cable, realize not only electric energy transmitting but also play control action that need conflux by means of custom-designed cable concentrator copper bar, not only cost is high; And the site operation difficulty is big, efficient is lower, converts focal point to useful electric flux and can only reach 10-19%; 2, the existing used conductor of photovoltaic wire is a tin-coated copper, and performances such as high-low temperature resistant and anti-daylight are not enough, and the electric energy transmitting effect is general, and the pliability of wire conductor is also not enough, and the overall routing of photovoltaic system is caused puzzlement.
The utility model content
The technical problem that the utility model will solve is the defective that overcomes prior art, provides a kind of electric energy transmitting flat twin-core photovoltaic cable big, easy for installation.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Comprise two transmission heart yearns, said two transmission heart yearns are parallel and column distribution, and the said transmission heart yearn outside is enclosed with insulated hull, and the said insulated hull outside is enclosed with sheath, is connected with disjunctor portion between the sheath of said two transmission heart yearns.
To be that 56 rhizoids are stranded form said transmission heart yearn.
Said disjunctor portion is thin concavo-convex in thick middle part, two ends.
Compared with prior art, the utlity model has following beneficial effect:
The flat twin-core photovoltaic cable of the utility model, two transmission heart yearns adopt parallel construction, and the centre has concavo-convex disjunctor to fix two heart yearns.Connect two photovoltaic junction box cell panels simultaneously, the technical problem of the heart yearn mistake relevant when having avoided welding again and having installed with the separate cabling engineering.
Description of drawings
Fig. 1 is the structural representation of the flat twin-core photovoltaic cable of the utility model.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1; Flat twin-core photovoltaic cable comprises two transmission heart yearns 1, insulated hull 3, sheath 4; Two transmission heart yearns 1 are parallel and column distribution; The insulated hull 3 that is enclosed with 3,2 transmission of insulated hull heart yearn in every transmission heart yearn 1 outside is respectively with black and white two kinds of color differentiatings, the mistake when avoiding welding and installing.Insulated hull 3 outsides are enclosed with between the sheath 4 of sheath 4, two transmission heart yearns 1 and are connected with disjunctor portion 2.
Transmission heart yearn 1 is 56 stranded forming of tinned copper wire, is used for connecting simultaneously two solar panels, strengthens the transmission of electric energy.
Disjunctor portion 2 is concavo-convex that thick middle part, two ends approaches, and its width is 0.50 ± 0.10mm, and thickness is 0.30 ± 0.10mm, tears 2 heart yearns separately with the have gentle hands loose ground when convenient welding and installation.
Insulated hull 3 is cross-linking radiation polyolefin (XLPO) with sheath 4 materials.
1. flat twin-core photovoltaic cable is two parallel constructions, and volume is little, connection is simple, convenient disassembly; Two core insulation layers are prone to identification with black and white two kinds of color differentiatings when welding and installation.Easy for installation, avoid occurring the random line of swinging cross, installation effectiveness is high.At cable bending and the copper conductor that reverses Shi Buhui damage the inside, satisfy difformity and special package dimension requirement.
2. flat twin-core photovoltaic cable can connect two photovoltaic junction box cell panels simultaneously, increases the area that absorbs luminous energy, and effective electric energy that focal point is converted to has obtained very big lifting.
3. the middle disjunctor portion concave-convex surface of flat twin-core photovoltaic cable, very thin thickness is torn 2 heart yearns separately with the have gentle hands loose ground, shortens process time like this, can not cause the oversheath skin to break again.
4. the sheath material of flat twin-core photovoltaic doubling is cross-linking radiation polyolefin (XLPO), has increased the soft degree of whole cable, and scratch resistance is good, and cable does not have white precipitate.
5. flat twin-core photovoltaic cable insulation cortex adopts the double-decker design, makes the anti-external mechanical force of whole cable strengthen, and installs out of doors and more has superiority when using.
The above is merely the execution mode of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
Claims (3)
1. flat twin-core photovoltaic cable comprises two transmission heart yearns, it is characterized in that; Said two transmission heart yearns are parallel and column distribution; The said transmission heart yearn outside is enclosed with insulated hull, and the said insulated hull outside is enclosed with sheath, is connected with disjunctor portion between the sheath of said two transmission heart yearns.
2. flat twin-core photovoltaic cable according to claim 1 is characterized in that: to be that 56 rhizoids are stranded form said transmission heart yearn.
3. flat twin-core photovoltaic cable according to claim 1 is characterized in that: said disjunctor portion is thin concavo-convex in thick middle part, two ends.
