STARIS-Sia+

RIS Transformer outdoor bushings

Free of partial discharges
High mechanical strength with fiber glass tube mounted insulator
Proven design with vacuum impregnated synthetic
Low operational cost with minor inspection scope
Low possible environmental impact, oil and SF6 free
Explosion-resistant - no porcelain or combustible fluids
Qualified for ambient temperature up to -60°C

The STARIS-Sia + is our standard IEEE bushing for 25 to 230 kV in RIS and a rated current of up to 3000A. It is an oil-free transformer bushing with a solid active part made of resin-impregnated synthetic fleece and a capacitor control. The air-side housing is a silicone composite insulator.

The STARIS-Sia + fully complies with IEEE C57.19.01 in terms of properties and dimensions and is tested in accordance with IEEE C57.19.00.
