Abstract

The invention relates to a comprehensive reinforced solar photovoltaic computer cable, particularly to a comprehensive reinforced solar photovoltaic computer cable structure, and belongs to the new technical field of cables. The comprehensive reinforced solar photovoltaic computer cable comprises four cable cores, and a total shielding layer and an outer protective layer are arranged in sequence outside the four cable cores; a reinforced steel wire is arranged among the four cable cores, and fillers are arranged between the four cable cores and the total shielding layer; each cable core includes two insulating wire cores which are intertwisted, sub-shielding layers are arranged outside the two insulating wire cores, each insulating wire core includes a conductor, and an insulating layer is arranged outside the conductor. The comprehensive reinforced solar photovoltaic computer cable in the invention is simple and convenient in technology and not high in cost, and has the characteristics of high temperature resistance, ozone resistance, ultraviolet ray resistance, small medium loss, strong anti-interference capability, high mechanical strength, good composite utilization effect, resistance to severe environment and the like, and is widely used in various fields such as security and protection engineering, firefighting engineering, monitoring engineering, solar energy power stations, photovoltaic systems and the like.

Description

Comprehensive reinforced photovoltaic computer cable

Technical field

The present invention relates to a kind of comprehensive reinforced photovoltaic computer cable structure, belong to cable new technical field.

Background technology

Solar energy is most important basic power source in various regenerative resources, biomass energy, wind energy, oceanic energy, water energy etc. are all from solar energy, in a broad sense, solar energy comprises above ... photoelectric conversion device normally utilizes the photovoltaic effect principle of semiconductor device to carry out opto-electronic conversion, therefore claims again solar-photovoltaic technology.

Heliotechnics is day by day extensive in China's application by becoming one of following green energy resource technology solar energy or photovoltaic PV, and except the photovoltaic generation factory development rapidly that government supports, private investor's plan of also just actively founding the factory is gone into operation at the solar components of global marketing.But many countries are still in learning phase for now.Certainly for obtain the best profit in the industry enterprise all need in country and the company aspect Application of Solar Energy with many years of experience, to learn to those.If fail to adopt the private cable of Application of Solar Energy will have influence on the useful life of whole system.

Summary of the invention

The object of cable of the present invention is in the deficiency aspect adverse environment resistant, to provide a kind of comprehensive reinforced photovoltaic computer cable with applicable this special occasions for traditional cable.

The present invention includes four groups of cable cores, in described four groups of cable cores outside, set gradually total screen and outer jacket; At the center of described four groups of cable cores, reinforcement steel wire is set, between described four groups of cable cores and total screen, filling is set; Described every group of cable core includes two stranded strand insulation cores mutually, and in described two strand insulation core arranged outside sub-shields, described per share insulated wire cores includes conductor, at described conductor arranged outside insulating barrier.

Conductor of the present invention adopts oxygen-free copper, described insulating barrier adopts the special-purpose low smoke and zero halogen cross-linked polyolefin cable material of photovoltaic, during stranding, adopt steel wire to strengthen structure, the core stranding of shielded type cable adopts double-deck copper wire composite shielding, and oversheath extrudes photovoltaic low smoke and zero halogen cross-linked polyolefin cable material.Just, cost is not high yet for cable manufacturing process cylinder folk prescription of the present invention, has high-temperature resistant, anti-ozone, uvioresistant, dielectric loss is little, antijamming capability is strong, mechanical strength is high, the compound features such as effective, adverse environment resistant of utilizing.Be widely used in the every field such as safe protection engineering, fire engineering, supervision control engineering, solar power station, photovoltaic system.
