Description
Technical field:
The utility model relates to cable, particularly relates to a kind of photovoltaic and power combinations cable.
Background technology:
Existing photovoltaic cable Main Function is the transmission of electric energy, but along with photovoltaic industry make rapid progress development, photovoltaic cable not only will meet the transmission of electrical property, and will meet the Signal transmissions for solar facilities.
But current photovoltaic cable has excellent cold-resistant, UV resistant, resistance to ozone and weatherability, but due to structural compactness design existing defects, cause its mechanical performance comparatively weak, such as do not reach the user demand of actual environment in stretch-proof, warp resistance performance; In addition, water resistance is also relatively weak.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of photovoltaic and power combinations cable, and structural compactness is good, has excellent mechanical performance and water resistance.
The technical solution of the utility model is as follows:
Photovoltaic and power combinations cable, comprise two spaced power conductors, power conductor is for being coated with polyolefin insulation layer, nonwoven fabrics lapping layer, tear-proof silicon rubber protective layer formation electric insulation core successively, and two electric insulation cores form electric power cable core through extrusion moulding in the polyolefin lining layer of dumbbell shape; The photovoltaic core that described electric power cable core bilateral symmetry is provided with pair twist forms combination cable core jointly; the photovoltaic core of pair twist is coated with high temperature resistance polyester film strip lapping layer, cross-linked polyolefin protective layer outward successively, and described combination cable core is coated with rock wool belt lapping layer, braid, watertight composition, external sheath layer outward successively.
Described photovoltaic and power combinations cable, is characterized in that: the conductor of the photovoltaic core of described pair twist adopts 19 diameters to be the tinned copper conductor of 0.12mm, and direction of lay is left-hand, and stranded pitch is 7mm.
The utility model has the advantages that:
The utility model structural compactness is good, can ensure the Signal transmissions of electric power and solar facilities, has excellent mechanical performance and water resistance, also has excellent cold-resistant, UV resistant, resistance to ozone and weatherability.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
See accompanying drawing:
Photovoltaic and power combinations cable, comprise two spaced power conductors 1, power conductor 1 for being coated with polyolefin insulation layer 2 successively, nonwoven fabrics lapping layer 3, tear-proof silicon rubber protective layer 4 form electric insulation core, two electric insulation cores form electric power cable core through extrusion moulding in the polyolefin lining layer 5 of dumbbell shape; The photovoltaic core 6 that electric power cable core bilateral symmetry is provided with pair twist forms combination cable core jointly; the photovoltaic core 6 of pair twist is outer is coated with high temperature resistance polyester film strip lapping layer 7, cross-linked polyolefin protective layer 8 successively; the polyolefin watertight composition 11 of the combination glass fiber yarn braid 10 that cable core is coated with rock wool belt lapping layer 9 outward successively, dip-coating has PTFE emulsion, the solidifying water-proof emulsion of interpolation third, the insulating material extrusion molding that modified polyvinyl resin, ultraviolet screener, stabilizer, light absorber and mould inhibitor are made through mixing, extruding pelletization forms external sheath layer 12.
The conductor of the photovoltaic core 6 of pair twist adopts 19 diameters to be the tinned copper conductor of 0.12mm, and direction of lay is left-hand, and stranded pitch is 7mm.
