Abstract
The utility model relates to the field of cables and discloses a photovoltaic cable, which comprises a center conductor, an irradiation crosslink insulating layer and a nylon sheath layer. The technical process includes that the conductor is extruded out of the insulating layer for irradiation and then extruded out of the nylon sheath. The photovoltaic cable is made of low-smoke zero-halogen flame-retardant insulating materials and the nylon sheath by means of advanced irradiation crosslinking process, has the advantages of high and low temperature resistance, ozone resistance, ultraviolet resistance, water vapor resistance, microbe resistance, high short-time overload capacity, long service life, abrasion resistance, oil resistance, corrosion resistance, high tensile resistance, low cost and the like, and is widely applicable to various fields of solar power stations, photovoltaic systems and the like.
Description
Technical field
The utility model relates to field of cables, relates to a kind of structure and manufacturing approach of photovoltaic cable, and this cable is used for every field such as solar power station, photovoltaic system.
Background technology
Heliotechnics will become one of following green energy resource technology; Solar energy or photovoltaic (PV) are used day by day extensive in China; Build the photovoltaic generation factory of the profitability of economical and efficient, the wiring system that connects photovoltaic module and inverter is a critical component, still; If fail to adopt the private cable of Application of Solar Energy, will have influence on the useful life of whole system.Solar energy system usually can use under severe environmental conditions, like high temperature and ultraviolet radiation.In Europe, the scene temperature that will cause solar energy system when fine is up to 100 ℃.At present, we have PVC, rubber, TPE and high-quality cross-linked material by adoptable various materials, and rated temperature is 90 ℃ a rubber cable, and rated temperature is that 70 ℃ PVC cable also usually uses out of doors, and obviously, this will influence the useful life of system greatly.The utility model is to utilize advanced cross-linking radiation technology; The cable that adopts low-smoke halogen-free flame-retardant isolating material and nylon sheath wire to produce; It has high-low temperature resistant, anti-ozone, uvioresistant, water-fast steam, antimicrobial, short-time overload capacity is strong, the life-span is long, wear-resisting, oil resistant, anticorrosion, high tensile property, low cost and other advantages, can be widely used in every field such as solar power station, photovoltaic system.
Summary of the invention
The purpose of the utility model is the weak point to above-mentioned existing photovoltaic cable existence, and long photovoltaic cable of a kind of high-performance, low cost and life-span is provided.
The utility model comprises center conductor, cross-linking radiation insulating barrier, the nylon sheath wire layer that sets gradually from the inside to the outside.Technical process is to carry out irradiation after conductor is extruded insulating barrier, extrudes nylon sheath wire again.
The cross-linking radiation insulating barrier of the utility model adopts low smoke, zero halogen cross-linking radiation polyolefine material, through the material of cross-linking radiation, possesses higher mechanical strength.Crosslinking process has changed the chemical constitution of polymer, and the meltability thermoplastic material converts non-meltability elastomeric material into, and cross-linking radiation has significantly improved thermal characteristic, mechanical property and the chemical characteristic of cable insulation material.
The nylon sheath wire of the utility model has following characteristics:
1, nylon sheath wire has excellent electrical insulation properties and physical and mechanical properties, and its tensile strength is more than 5.5 times (79MPa) of polyvinyl chloride, is described as " soft armouring ", can effectively prevent to cause the hidden danger of accident of power supply because of muroid bites.
2, high and low temperature resistance is good, serviceability temperature-40 ℃～121 ℃, and nylon is the binary states material, has only glassy state and viscous state, do not have elastomeric state, even under 150 ℃ high temperature, also do not see tangible metaboly.This anti-deforming performance and weightless little characteristics can improve electric wire moment heat resistanceheat resistant overload capacity and the effusion or the migration that slow down or reduce the insulation component.
3, anti-wear performance is good.
4, chemical stability is good, can oil resistant, anti-hydrocarbon etc.
