The Anti-fog Suspension Porcelain Insulator is a specialized component for overhead power transmission and distribution systems, tailored for foggy, humid, and heavily polluted environments. Made from high-quality electrical porcelain with optimized raw material ratios, it undergoes precision molding, anti-fog glazing, and high-temperature firing to ensure superior performance.
Its distinctive large-diameter, deep-umbrella structure enhances creepage distance, preventing water film formation and flashover. The hydrophobic anti-fog glaze repels moisture and pollutants, facilitating rainwater washing. Equipped with reliable metal cap-pin connections, it can be serially assembled for different voltage levels, with strong resistance to UV radiation, acid rain, and salt spray.
Widely used in coastal, mountainous foggy, and industrial areas, it ensures stable operation of medium to ultra-high voltage lines. With long service life and low maintenance, it is a reliable choice for improving power grid stability in harsh weather conditions.

Company Profile
Nanjing Electric was founded in 1936 and is the first high-voltage ceramic manufacturer in the history of China's electrical industry. It is also the headquarters of Baiyun Group in the East China region. Nanjing Electric has been rated as one of the top 500 mechanical industrialization enterprises in China and a first-class industrial enterprise in China. At present, the base covers an area of 19 hectares and employs 1000+ people. The industrial base was put into operation with equipment in 2015. Nanjing Electric specializes in developing glass insulators, composite insulators, and ceramic insulator products. In 1958, China developed the first Tempered Glass insulator and condenser Bushing, filling the domestic gap. The company's products are exported to more than 120 countries and regions around the world, such as the Americas, Australia, the Middle East, Southeast Asia, and more than 50% of countries and regions in Europe. The main customers are national power grid companies or local power grid companies in various countries. The domestic market has achieved full coverage. The company's products are widely used in national strategic projects, including 33 UHV projects above 800KV. Our company is the largest insulator supplier in national engineering.
Nanjing Electric International Co., Ltd., formerly known as the Overseas Business Unit of Nanjing Electric Technology Group, established an international trade company in 2021 based on the development strategy of the group. With insulators and sleeves as the two flagship exhibits, the company actively carries out resource and multi-party cooperation around common values and market views. On the way to the world, international trading companies will firmly step forward and work hard for the century old white clouds and the world's white clouds.
The international trade team participated in international power exhibitions held in countries each year such as Germany, the United States, Brazil, Saudi Arabia, Egypt, India, Italy, Saudi Arabia, Australia, the Philippines, Thailand, Spain, Mexico, etc; Track the progress of key power projects in various countries; Further promote the internationalization process of products.
Facing the future, the company will focus on the needs of national power construction, seize the opportunities of new power infrastructure, ultra-high voltage projects, the "the Belt and Road" construction, and the development of green energy. According to the strategic positioning of Baiyun Electric Group to build the company into the second headquarters of the group relying on the Yangtze River Delta, the company will build and develop a world-class insulator and related product R&D and production base, explore and build new products, new technologies, and new formats, Make new contributions to national power construction and global power development, and strive to become a century old enterprise.
