Oil-SF6 Bushing is a specialized and essential connecting component designed for the direct interface between oil-filled transformers and SF6 metal-closed switchgear (GIS). It serves as a critical bridge for power transmission and insulation between these two core pieces of power equipment, ensuring seamless and safe energy transfer in power grid systems. A notable advantage of this bushing is its flexible installation capability, supporting horizontal, vertical, or any angular mounting, which greatly enhances its adaptability to diverse substation layout and equipment arrangement requirements.
In terms of customization, the design and dimensions of the bushing’s flanges and connecting terminals can be tailored according to client specifications. This personalized design ensures perfect compatibility with different types and models of oil-filled transformers and GIS equipment, effectively addressing the connection matching challenges in various power project scenarios. Crafted with high-quality insulating materials and precision manufacturing processes, it exhibits excellent electrical insulation performance, corrosion resistance, and mechanical stability, capable of withstanding the harsh operating environments of power substations.
The bushing covers a wide range of rated parameters, with a rated voltage of 12~550kV and a rated current of 630~6000A, making it suitable for medium and high-voltage power system applications. It plays an indispensable role in ensuring the reliable connection and stable operation of oil-filled transformers and GIS equipment, contributing to the overall safety, efficiency, and continuity of power transmission in substations.

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.
