Ceramic bushing insulators mainly used on device and plant construction, such as Disconnect switches and Circuit Breakers (live tank breakers, dead tank breakers); Current converters, voltage converters, surge arrestors, insulator bushings. Conical design and cylindrical design are available. The porcelain hollow core insulators voltage can be 10KV, 20KV, 30KV, even under 1KV.

Standards: DIN and EN; IEC, ANSI and C130, DIN 42530, DIN42531, IEC 62155, IEC 60672, IEC TS 62371, ANSI
