Vaultmount 2 Way Switchgear Products

Innovative Switchgear’s solid-dielectric-in-air vaultmount switches and fault interrupters are fully factory assembled. Our equipment is compact and replicates the size, shape, and bushing patterns of old oil-filled and SF6-filled switchgear without the presence of oil and SF6 gas. One key advantage of the compact size is that utilities can now add fault interrupting capabilities where they previously only had switching capabilities. Our designs can feature up to six ways in a single unit, are available in 12.5kA, 16kA and 20kA, and are suitable for 4kV – 27kV applications. We feature our visible open isolation point which is visible from a safe working distance away from the switchgear. Each unit is constructed of 304 stainless steel, and is sealed and dead-front. All of our vaultmount products come with an adjustable mounting stand which can be raised or lowered to match existing cable termination lengths. Our vaultmount products are submersible and fully-sealed, and not subject to moisture intrusion. It is the ideal solution for new and replacement projects.
