RIP Bushings

ABB's new GSB line of bushings is available for 245-kV/362-kV/420-kV voltage classes and soon will also include the 550-kV class. GSB is intended for oil-to-air applications and is available with either porcelain or silicone insulators.
RIP bushings feature several tests to ensure optimal working performance:

· To ensure the production process, each RIP bushing is subject to an electrical routine test sequence before being cleared for delivery. The ABB acceptance criteria exceed the international standard for RIP bushings.
· To ensure the design, each new product family, such as the GSB, has to be type tested in compliance with the international standards or higher.
· ABB also carries out comprehensive testing programs to verify certain characteristics unique to RIP bushings.
