The utility model discloses can be on the basis that keeps the outside diameter of cable, reduce cost, improve the pressure resistance of photovoltaic cable, the insulation can be through 6.5kV15min voltage test and do not puncture.
Description
Technical field
This utility model belongs to cable technical field of cables, particularly to a kind of PV1-F photovoltaic cable.
Background technology
The low-voltage DC that photovoltaic generation produces needs to be converted into alternating current, and photovoltaic cable be used for connecting photovoltaic cell with
Alternating current-direct current inverter, photovoltaic generating system is required to use photovoltaic cable.Photovoltaic installation during China's preliminary planning " 13 "
Size target will reach 1.5 hundred million kilowatts about, and the solar electrical energy generation of 1kW will be about the photovoltaic cable using 25m, and photovoltaic cable needs
Seek about 3,750,000 km.
Photovoltaic market expands year by year, and existing photovoltaic cable conductor is tinned copper conductor, and this conductor forms for bundle strand, leads
Body is loosely organized, uneven, causes insulating barrier eccentric, and then affects photovoltaic cable integrally pressure performance.And other producers then increase
Plus insulation thickness, to improve insulation thinnest point thickness, improve insulation resistance energy, cause cost to waste.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, there is provided a kind of PV1-F photovoltaic cable, should
Cable on the basis of keeping the outside diameter of cable, reduces cost, can improve the pressure performance of photovoltaic cable.
For reaching above-mentioned purpose, this utility model employs the following technical solutions：
A kind of PV1-F photovoltaic cable, including the insulated single wire setting gradually from inside to outside and outer jacket；Described insulated single wire
It is made up of with the insulating barrier being arranged on copper conductor periphery copper conductor, between insulating barrier and outer jacket, be provided with sealing coat.
Described copper conductor is tin plating copper stranded conductor, and tin plating copper stranded conductor twists using bundle strand mode or layer that mode is stranded to be formed.
The external diameter of described copper conductor is not more than 2.46mm.
Described insulating barrier is extruded with 125 DEG C of low smoke halogen-free flame-retardant polyolefin Insulation Material by photovoltaic cable and forms, and thickness is not low
In 0.8mm.
Described insulating barrier concentricity is not less than 90%.
Described outer jacket is extruded with 125 DEG C of low-smoke and halogen-free flame retardant polyolefin jacket materials by photovoltaic cable and forms, and thickness is not low
In 0.8mm.
Described sealing coat is Pulvis Talci or mould release.
With respect to prior art, this utility model has the advantages that：
A kind of PV1-F photovoltaic cable described in the utility model, to conductor, tin plating copper stranded conductor carries out sizing and presses, both permissible
Reduce conductor diameter, conductor can be made again uniform, compact, not loose.Insulation eccentricity can be controlled well, simultaneously during insulation extrusion
Under same cable external diameter, due to the reduction of conductor diameter, thickness of insulating layer is improved in right amount.So, this utility model energy
Enough on the basis of keeping the outside diameter of cable, reduces cost, improve the pressure performance of photovoltaic cable, insulation can be through 6.5kV/15min
Voltage test and do not puncture.
Further, described sealing coat is made up of Pulvis Talci or mould release, prevents insulating barrier and restrictive coating adhesion.
Further, insulating barrier and outer jacket are all squeezed with 125 DEG C of low smoke halogen-free flame-retardant polyolefin Insulation Material using photovoltaic cable
System forms, and tolerance high-temperature behavior is good, material environment friendly.
