Photovoltaic cable for solar equipment

Abstract

The invention discloses a photovoltaic cable for solar equipment. The photovoltaic cable comprises a cable core and an outer sheath, wherein the cable core is wrapped by the outer sheath; the outer sheath comprises the following raw materials in parts by weight: 40-60 parts of silicon rubber, 5-15 parts of polytetrafluoroethylene, 1.5-2.5 parts of a plasticizer, 1-2 parts of POE (Polyolefin Elastomer) plastic, 0.1-0.6 part of polyether-ether-ketone, 30-50 parts of a bamboo powder compound, 1-5 parts of stearic acid, 5-10 parts of nano calcined kaolin, 2-6 parts of dicyandiamide phosphate, 2.5-3.5 parts of a cross-linking agent, 1-2 parts of m-isopropenyl-2,2-dimethyl benzoyl isocyanate, 0.2-1.2 parts of a silane coupling agent Si69 and 2-4 parts of tri(dioctyl pyrophosphoryl oxo) titanium isopropoxide. The photovoltaic cable is good in elasticity, excellent in distortion resistance and good in interference resistance and reciprocation bending property, and in addition, due to formed high-temperature resistant chemical bands, a fire hazard is not easily caused even if the photovoltaic cable is in a high-temperature harsh environment, and cable short circuits can be also avoided.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a photovoltaic cable used for solar energy equipment. Background technique [0002] The rapid growth of my country's photovoltaic industry has now become the world's largest producer of photovoltaic cell modules. The national ministries and local governments have successively introduced measures such as financial subsidies and scientific and technological support to promote the growth of the photovoltaic industry and photovoltaic application market. The industry is also constantly working on key materials and key technologies. By 2020, my country's photovoltaic power generation installed capacity is likely to exceed 30-50 million kilowatts, photovoltaic manufacturing costs are also declining, and the service life of solar equipment is as long as 20-50 million kilowatts. For 30 years, special photovoltaic cables must be used in solar equipment, otherwise it will affect the service l...

Problems solved by technology

The industry is also constantly working on key materials and key technologies. By 2020, my country's photovoltaic power generation installed capacity is likely to exceed 30-50 million kilowatts, photovoltaic manufacturing costs are also declining, and the service life of solar equipment is as long as 20-50 million kilowatts. For 30 years, special photovoltaic cables must be used in solar equipment, otherwise it will affect the service life of the entire system. Solar equipment is often in harsh environmental conditions. If ordinary cables are used, the cable sheath is easily broken, which is easy to cause cable short circuit , cause fire or personal injury, need to be solved urgently
