Technical field
The utility model is related to a kind of cable more particularly to a kind of fire-retardant waterproofing type twin-core solar photovoltaic cables of tension.
Background technology
Since usually (such as high temperature, ultraviolet radiation, ozone, dramatic temperature become solar energy system in harsh environments
Change, violent storm and chemical erosion etc.) use, therefore photovoltaic cable must have best weather resistance, UV resistant and
Resistance to ozone attack, and larger range of temperature change can be born, can be resisted in corresponding device extreme climate environment and
It is subjected to mechanical shock.But current photovoltaic cable is all single structure, there was only one layer of insulation, sheath outside conductor, to severe
Weather resilience is weak, is highly prone to external strength destruction, more serious to cause short-circuit fire.Simultaneously in mounting and installation
Afterwards, positive and negative anodes vacantly detach below solar panels, scatter, it appears and it is in disorder, very it is to influence beauty.
Utility model content
The utility model provides in order to solve problem above a kind of having excellent insulation performance, mechanical strength, fire-retardant
Block-water performance, weather-resistant property etc. disclosure satisfy that the fire-retardant waterproofing type twin-core of tension of normal operation under the conditions of extreme climate environment
Solar photovoltaic cable.
The technical solution of the utility model is：The cable includes cable core, is set successively from inside to outside outside the cable core
Set waterstop wrapping layer, flame-retardant layer, armor, oversheath；The cable core is made of two insulated wire cores, the insulated wire
Core includes strengthening core, conductor layer, separating layer, insulating layer, and the conductor layer is coated on the periphery of strengthening core, the insulating layer
It is extruded in conductor layer periphery, separating layer is equipped between insulating layer and conductor layer.
The strengthening core is the steel wire that periphery is coated with tin layers.
The conductor layer is that the second class tin-coated copper monofilament is selected to be formed around the periphery of strengthening core.
It is described that separating layer is dispersed in by inorganic nano powder in liquid low molecule, it is pumped into extrusion head, by dividing
Glassware, uniform extrusion molding are constituted in conductor layer.
The insulating layer is extruded in by low-smoke non-halogen flame-retardant Radiation Crosslinked Polyethylene photovoltaic PP Pipe Compound on layer free of conductors
It constitutes.
The waterstop wrapping layer is the compound waterstop of water-swellable, using double-deck wrapped.
The flame-retardant layer is that flame retardant type ceramic silica gel composite band bilayer is wrapped.
The armor is aramid fiber composite band.
The oversheath is that 125 DEG C of low smoke and zero halogen cross-linking radiation polyolefine materials of extrusion type are extruded in structure on enhancement layer
At.
The utility model has the beneficial effects that：
One, conductor layer is formed using the second class tin-coated copper monofilament around the periphery of strengthening core, and the structure tensile property is strong,
Electric conductivity is excellent, and stability is good, and service life is long.It is tin plating in the periphery of strengthening core and conductor periphery, enhance corrosion resistant performance；
Two, separating layer is set between conductor and insulating layer.Inorganic nano powder is dispersed in liquid low molecule,
It is pumped into extrusion head, by tripper, uniform extrusion molding is on conductor, and very thin thickness, good electrical property, the cost of material is low.
Three, insulating layer uses extrusion type low-smoke non-halogen flame-retardant cross-linking radiation polyolefin photovoltaic PP Pipe Compound, improves product
Electrical property, heat resistance and LSOH anti-flaming performance.
Four, wrapped using waterstop bilayer outside cable core, it can effectively prevent water from passing through the gap edge between cable core and flame-retardant layer
Cable vertical migration.
Five, select flame retardant type ceramic silica gel composite band bilayer wrapped, every layer of cap rate is not less than 60% so that cable is often located
Ceramic silica gel composite band is not less than 4 layers, so that cable is not only had excellent fire prevention, Fire resistances, but also can ensure that cable-flame retardant
Performance reaches the requirement of A classes.
Six, it is provided with aramid fiber enhancement layer, not only makes that the structure of product is compacter, rounding, but also is further increased
The tensile property of product.
Seven, oversheath extrudes 125 DEG C of low smoke and zero halogen cross-linking radiation polyolefine materials and is carried after high-energy electron irradiation is crosslinked
High temperature in use, while there are the performances such as excellent UV resistant, heat-proof aging, corrosion-resistant, oil resistant, low-smoke non-halogen flame-retardant,
The needs of solar power station, photovoltaic power system can be met.
