Silicone bushings

Bushings for MV applications (IEC standard) designed with future requirements in mind

The Silicone Bushing Composite (SBC) range, comprising the latest technology for bushings, is the response to the ever-increasing demand for an efficient and reliable product that can help optimizing the total operational costs of the transformer. This use of silicone technology ensures that the bushing is safe and maintenance free, and therefore has a longer service life.
