Transformer Equipment Bushings
Transformer Equipment Bushings
Reliable Solution for Isolating Your Transformer;
Transformer Bushing consists of insulator, metal fittings and seal groups used for the entry of a conductor into the transformer tank; isolating the conductor against the tank.
The products used in both power and distribution transformers are DIN, EN, IEC, AS norms with their own specific design, products designed in accordance with customer needs and expectations.
All products are available in our production range according to the standards between 1,2 kV 250 A-5000 A, 52 Dec 250 A-8000 A and the climatic conditions of the place of use.
