Questions and answers
How does RIS differ from RIP?
In an RIS bushing, resin-impregnated synthetic material is used instead of paper, so the insulation is paper-free.
What ratings are the bushings designed for?
Voltage class up to 550 kV, rated current up to 6000 A, oil-to-air design.
What housing does the bushing have?
A composite housing made of a fibreglass tube with silicone sheds.
