GROUNDING SWITCHES

Ratings: 15kV-550kV, up to 63kA 3sec (164kA Peak)

Robust & Reliable

EMSPEC offer a wide range of grounding switches in stand-alone or built-on configuration.

All EMSPEC ground switches are built on the keep it simple principle, through innovative design to provide high performance and reliability. Only the best materials are used for its fabrication.

COMPACT DESIGN

Image on the left shows an ST18503 with the 3 blades contained within the support structure girder . The center image shows the same ST18503 model combined to a 145kV double end break D.S.. The motion of the ground blade is paralelle to the base frame of the main switch. The image on the right shows a GSA36135 double motion perpen- dicular grounding switch.
