Generator Lead-out Bushing is a critical and indispensable component in power station generator systems, specifically designed to safely lead the stator current from the internal part of the generator to the external circuit. As a key interface for power transmission between the generator and the external power grid, it directly affects the efficiency and reliability of the entire power generation system, making it a core part of power station equipment.
A standout feature of this bushing is its advanced insulating structure: it adopts a fiberglass-impregnated epoxy resin reinforced winding capacitive insulation design. This innovative structure effectively avoids the common risks of traditional porcelain bushings, such as cracking, oil leakage, and explosion. By eliminating these potential hazards, it significantly enhances the operational stability and reliability of the generator, reducing the probability of unplanned downtime and ensuring continuous power generation.
With a rated voltage range of 12~40.5kV and a rated current range of 630~4000A, it perfectly matches the operational requirements of various medium-power generators in power stations. Crafted with high-quality materials and precision manufacturing processes, it also boasts excellent electrical insulation performance, heat resistance, and mechanical stability. As a reliable guarantee for the safe and efficient operation of power station generators, it is widely trusted in the power generation industry.

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.
