HSP is the leading manufacturer of RIP condenser transformer bushings to the highest voltage & current ratings. HSP supply their RIP bushings with either silicone rubber or porcelain insulators. In Australia HSP bushings are commonly seen on the large power transformers in the networks of utilities such as Powerlink, Transgrid, Western Power and Ausgrid to name a few.
MGC is growing rapidly as a manufacturer of RIP condenser transformer bushings using directly bonded silicon rubber insulators manufacturing bushings from 24kV up to 300kV rated voltage and 3150A rated current. The transformer bushings use MGC’s patented TRAVESCA RIP technology, ensuring fine grading of the insulating body.
MGC specialises in like-for-like (retrofit) replacement of transformer bushings to existing transformers; the flange and critical dimensions of the existing bushings can be matched to provide a very cost effective means of extending the life of the transformer.
