STARIS-Sia+

RIS Transformer outdoor bushings

Overview

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.
