Product Details
Porcelain dry bushing is a core insulation connector for power transformers, switchgears, transformers and other high-voltage electrical equipment. Adopting oil-free dry insulation design, it uses high-purity alumina high-voltage porcelain as the main insulation body, paired with high-quality copper conductive rods and sealing parts, to achieve insulation isolation and current transmission between internal conductors and external shells of equipment. It is widely used in power grid transmission, industrial power supply and new energy power generation, ensuring stable operation of high-voltage equipment.
