G&W model TVI padmount switches include load break and fault interrupting capability. The load break switch features visible break and integral ground position. The integral ground position eliminates the need to handle any high voltage connections to ground the cable connected to the load break ways. The fault interrupters provide electronically controlled, resettable over current protection in a totally sealed, dead front device. The TVI can be configured to provide 1-phase or 3-phase operation of the fault interrupting ways. The switches are designed for use on 3-phase systems with voltages up to 38kV, 630A load break and continuous current, with 12.5kA or 20kA symmetrical fault interrupting ratings. The TVI is one of G&W’s most versatile switch styles because it can be ordered with front accessible switch operators and bushings (front access) as well as front and back access to replace existing pad mount air gear installations
The switches are designed to IEEE C37.72, C37.74, and C37.60 for load break and fault interrupting capability. Padmount enclosures are designed and tested to IEEE C57.12.28 and C57.12.29.
