Traditional flame-retardant PVC sheathed cables are mainly used in distribution lines, and the laying environment is mainly in the air or in the soil with less additional performance. If used in the harsh environment of photovoltaic system deployment, due to the use of materials containing halogen polymers and a large amount of halogen flame retardant, as long as the cable is in contact with the flame, combustion will produce a large number of harmful corrosive halogen acid gases and smoke, Corrosion of instruments and equipment causes "secondary disasters." There are more and more solar photovoltaic installations in China. The cables used in photovoltaic systems should have no harmful corrosive halogen acid gas. They can resist moisture, water, acid and alkali, and prevent photoaging. Therefore, the technical content of the cables used in photovoltaic systems will increase. The higher is.
At present, some cable manufacturers have developed environmentally friendly solar photovoltaic systems, most of which are designed and manufactured in accordance with German TUV standards. They are halogen-free, UV-resistant, ozone-resistant, flame-retardant, oil-resistant, and radiation-resistant. Photovoltaic system requirements for the use of cables, the broader market prospects.
Solar power, also known as "photovoltaic power generation." In simple terms, solar cells are used to convert solar energy directly into electrical energy based on the photovoltaic effect principle. More importantly, solar photovoltaic systems can generate electricity on sunny and cloudy days. Compared with traditional thermal power generation, solar photovoltaic power generation has the advantage of reducing emissions of carbon and sulfur compounds, thereby effectively reducing the greenhouse effect. on the other hand. As a resource, solar energy has the advantage of being "inexhaustible and inexhaustible." This is incomparable with traditional fossil energy.
Judging from the technical conditions, foreign photovoltaic power generation technology has a history of more than 30 years. It has matured, and some of these countries have already built solar power generation networks to achieve the civilian use of solar power. At present, China's solar cell production process is very close to the international advanced level.
On February 28, 2005, the Standing Committee of the National People's Congress approved the adoption of the "Renewable Energy Law," and came into effect on January 1, 2006. This law contains special provisions for supporting photovoltaic power generation. On September 7, 2009, the National Development and Reform Commission released the medium and long-term development plan for renewable energy. It is proposed that by 2010, the cumulative installed capacity of photovoltaic power generation will reach 300,000 kilowatts, and by 2020, it will reach 2 million kilowatts. These overall policy frameworks will create a good policy outlook for solar power generation.
The environment-friendly cable used in solar photovoltaic systems is a single-core flexible cable used in the solar photovoltaic system from the photovoltaic cell to the DC terminal of the PV converter. It is an important component of the photovoltaic device and serves as a solar photovoltaic power generation facility. The backbone is directly related to the safety, reliability and advancement of solar photovoltaic power generation systems. For the special environment for the installation of solar photovoltaic cables, the cables are required to be flame-retardant, oil-proof, sun-resistant, anti-acid, and alkali-resistant. They must also have environmentally friendly properties.
Special environment for installation of solar photovoltaic cables
With the increase in the construction of solar photovoltaic power system facilities, the use of cables is increasing. The cables used in all photovoltaic systems must be halogen-free special cables with flame retardant, fire-retardant, non-toxic, and sunlight-resistant properties. This will greatly promote the development of environmentally friendly cables for solar photovoltaic systems.
