Ceramic Spacer and Shunt Reactors

Shunt Reactors are the most compact & cost efficient means of compensating capacitive generation in long transmission high voltage power lines & extendable systems.

Why Steatite ? Steatite ceramic main features are

  • High resistivity.
  • Moderate strength.
  • Excellent electrical insulation properties.
  • Low coefficient of thermal expansion.
  • Good mechanical stability.
  • Economically manufactured to close tolerances & complicated shapes

The heart of every Shunt Reactors is its core. Precisely ground Ceramic Spacer is the key to manufacture a high quality core.

To produce low noise & low levels of vibrations a high quality precise core is required, for that ceramic spacers are precisely ground to parallelism of 0.01mm. These Ceramic Spacers are tightly glued on top surface of case pocket with special adhesive under vacuum and then subsequently pressed tightly under pressure so as to achieve desired flatness and parallelism on top & bottom surface. Ceramic Spacers for Shunt Reactors are manufactured as per customer's specification.
