Polymer Bushing for Switchgear
PRODUCTS

APPLICATION
Bushings are used to provide the essential insulation when a high voltage line passes through a metal sheet or
frame that is at ground potential. Primary Disconnect Bushings are the key components of the switchgear that serve as the connection points to
energize the network downstream of the switchgear.
CHARACTERISTIC
- Switchgear and power apparatus installations
