The construction of UHV AC transmission project in China belongs to a worldwide pioneering undertaking. There is no available overseas engineering experience for reference, and no standard norms can be consulted. Will face many major technical difficulties, such as UHVDC line insulation problem has become an urgent issue. June 22, China Electricity Council held in Beijing, the technical identification of products that Jiangdong Equipment Co., Ltd. developed a "1000kV AC rod-shaped composite insulator," the comprehensive technical performance reached the international advanced level, can be put into production , And suggested that the network as soon as possible, accumulated operating experience. China's altitude above 1000m of the area accounts for about two-thirds of the land area, the four plateaus of the average elevation above 1000m, and these areas is rich in water resources, coal, oil and other energy base, and Due to the harsh climatic conditions and serious industrial pollution in our country, high altitude and heavy pollution are the unique technical problems that UHV transmission projects in China are facing. It can be foreseen that the pollution flashover problem will be the most safe operation of 1000kV UHV AC transmission and transformation equipment One of the threats. Expert analysis pointed out that a large number of operating experience has confirmed that the silicone rubber for the umbrella sheath composite insulator has excellent flashover resistance, so 1000kV AC UHV line composite insulator to solve the problem of external insulation is scientific. At present, China's production of composite insulators has reached the world advanced level of technology, fully capable of designing and developing suitable for 1000kV AC UHV line composite insulator products, the use of composite insulators for UHV transmission lines is not only necessary but also feasible . At present, some countries with rapid economic growth, such as India and Brazil, have also begun to study the issue of developing UHV power grids. Therefore, 1000kV UHV AC composite insulators have broad market prospects. Composite insulator is a high-tech product. Its birth provides new equipment for the development of power construction and the safe operation of transmission lines. As a replacement product of porcelain and glass insulators, the composite insulator has a good market prospect and a vast market. At present, composite insulators have been designed and used in national new construction and key projects, and composite insulators have been widely accepted by the power sector. Relevant domestic manufacturers have successively developed a full range of AC and DC line composite insulators, hollow composite insulators, composite insulators and composite electrical casing composite insulation products. Jiangdong Hardware Equipment Co., Ltd. is a subsidiary of Zhongtian Science and Technology Group, specializing in the production of line fittings and optical fiber fittings, composite insulators, photovoltaic support and communications equipment, is a collection product development, production, sales and service in one of the modern enterprise.
