Application analysis of photovoltaic cables
Photovoltaic cables refer to cables used for transmitting electrical energy between solar power generation equipment and its connecting systems. Photovoltaic cables are widely used in the connection equipment of new energy photovoltaic power generation systems and are also an important component of the power system composed of solar panels. Photovoltaic cables have been widely used in the field of new energy due to their unique advantages such as high temperature resistance, special weather conditions resistance, and UV resistance.
1. Characteristics
Due to the unique climate and environment of solar power generation systems, they need to have various characteristics, including high temperature resistance, cold resistance, corrosion resistance, etc. Among them, it is particularly worth mentioning the UV resistance characteristics of photovoltaic cables, as there is a large amount of UV radiation in the sunlight. Ordinary cables (such as steel core aluminum stranded wires) are prone to aging and failure when exposed to sunlight for a long time, and photovoltaic cables are an ideal material to deal with this situation.
2. Classification
According to the different materials and uses of photovoltaic cables, they can be roughly divided into three types: silicone photovoltaic cables, TPE photovoltaic cables, and PVC photovoltaic cables. Silicone based photovoltaic cables have characteristics such as high temperature resistance, A-grade flame retardancy, and oil resistance, making them widely used in high-temperature and high-voltage electrical systems. TPE material for photovoltaic cables is a relatively new type of cable material, which is highly favored by the market due to its small flexibility, light weight, and low cost. PVC material photovoltaic cable is a very common type of photovoltaic cable, which has the characteristics of low cost and easy processing and molding. Due to its strong applicability, its market is also very wide.
3. Application field
Widely used in solar power generation systems, wind power generation systems, and other new energy and energy-saving projects. In solar power generation systems, photovoltaic cables are mainly used for energy transmission between solar panels and strings, between strings and inverters, and between inverters and distribution. In wind power generation systems, photovoltaic cables are used to directly connect the impeller of the wind turbine to the main shaft.
4. Manufacturing process
The manufacturing process is basically the same as ordinary cables, and the differences in manufacturing process are mainly reflected in the selection of metal materials and the addition of special shell materials. During the production process, it is necessary to conduct inspection, drawing, twisting, peeling, skin injection molding, drying treatment, and testing packaging on the wires to ensure that the electrical and physical properties of the products meet national and industry requirements.
How to choose the right product in the photovoltaic cable market?
In the process of product selection, many factors need to be considered, such as the high voltage, outer diameter, insulation thickness, and so on of photovoltaic cables. In addition, it is also necessary to consider factors such as the durability and usage environment of photovoltaic cables. For different usage scenarios, multiple factors can be considered comprehensively to select photovoltaic cable products that meet one's own needs.
Overall, photovoltaic cables are an indispensable and important link in the field of new energy. With the continuous development and application of new energy, the future development space of photovoltaic cables in the market will also continue to expand.
