Abstract

The utility model discloses a novel photovoltaic cable and a high flame-retardation tape isolation layer is wrapped on an insulation core in an overlapping manner. A thermosetting non-halogen low-smoke flame-retardation polyolefin oversheath is extruded on an outermost layer of the cable. The insulation core comprises aramid fiber yarn arranged in a core center, a plurality of strands tin-coated copper conductors bunched outside of the aramid fiber yarn, and an irradiation-crosslinked polyethylene and irradiation-crosslinked polyolefin double-layer insulation layer extruded on the tin-coated copper conductors. The novel photovoltaic cable has excellent anti-corrosion, oil resistant, flame retardation, non-halogen, non-lead, low smoke, ozone resistant, ultraviolet ray resistant, high and low temperature resistant and thermal aging resistant characteristics.

Description

A kind of Novel photovoltaic cable

Technical field:

The utility model relates to a kind of Novel photovoltaic cable, belongs to technical field of electric wires and cables.

Background technology:

Along with the development and utilization of Chinese solar energy new forms of energy, solar photovoltaic cable will obtain development at a high speed as the auxiliary products that solar energy utilizes.Solar photovoltaic cable is mainly used in the transmission of the collection of solar energy and the electric power transfer between the application apparatus, control signal, is the neural lifeblood of solar power system, plays an important role for the normal operation of solar power generation.Because the particularity of institute's environment for use of solar photovoltaic cable and key, just require cable must adopt special-purpose photovoltaic cable product, cable should have UV resistant, high-low temperature resistant, oil resistant, heat-proof aging, anticorrosion, heat-proof aging, Halogen, low cigarette, the characteristic such as fire-retardant.

The at present manufacturing of the solar photovoltaic cable of China also is in the primary stage, add that the technical merit of domestic each cable producer and level of processing are uneven, and the requirement of photovoltaic cable is comparatively strict, has caused certain production difficulty to domestic manufacturer.This just requires the producer must the break-through skill barrier, sets up the R﹠D team of oneself, develops the product with independent intellectual property rights, like this, will drive utilization and the development of solar energy new forms of energy, will produce good society and economic benefit.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of Novel photovoltaic cable, have excellent UV resistant, high-low temperature resistant, oil resistant, heat-proof aging, anticorrosion, heat-proof aging, Halogen, low cigarette, the characteristic such as fire-retardant, can the extensive use solar photovoltaic generation system etc. place electric power, control signal system, excellent product performance.

The utility model technical solution problem adopts following technical scheme:

A kind of Novel photovoltaic cable, the overlapping high flame retardant band separator that is surrounded with outside insulated wire cores, the outermost layer of cable is extruded with thermosetting halogen-free and low-smoke flame-retardant polyolefin oversheath;

Described insulated wire cores comprises: be in the aramid yarn at core center and bundle and close multiply tinned copper conductor outside described aramid yarn, extrude IXPE and cross-linking radiation polyolefin double hyer insulation layer on described tinned copper conductor.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model conductor adopts the multiply bundle to close the tinned copper conductor structure, and the middle high strength aramid yarn that adopts has improved tensile property, bending property, the decay resistance of cable greatly as strengthening core, improves the useful life of cable.

2, insulation adopts bilayer to extrude structure in the utility model, 135 ℃ high insulation irradiation polyethylene insulation materials are adopted in interior insulation, external insulation adopts 135 ℃ of irradiation crosslinking halogen-free low-smoke flame-proof polyolefin insulating material, double hyer insulation is after electron irradiation is crosslinked, mechanical performance improves greatly, guarantees that cable has excellent mechanical performance.Serviceability temperature reaches 135 ℃ simultaneously, compares with common cable, and ampacity obviously improves, and rise appreciably useful life.Adopt double hyer insulation expressing technique technology, inside and outside insulation thickness ratio is 4:6, has guaranteed that not only cable has excellent high electrical insulation properties, and guarantees that cable has excellent LSOH anti-flaming performance.

3, extrude thermosetting halogen-free and low-smoke flame-retardant polyolefin oversheath in the utility model behind electron irradiation, serviceability temperature reaches 125 ℃, have simultaneously excellent UV resistant, high-low temperature resistant, oil resistant, heat-proof aging, anticorrosion, heat-proof aging, Halogen, low cigarette, the characteristic such as fire-retardant, can the extensive use solar photovoltaic generation system etc. place electric power, control signal system, excellent product performance.
