TFI / TVI / TNI / GNI Switchgear with Integral Ground and Fault Interrupting

The G&W Electric TFI, TVI, TNI and GNI are 15–38 kV SF6 switchgear models combining load break, fault interrupting and integral grounding for underground distribution, sold and supported in Texas and Oklahoma by Ryan Sales.

  • 15.5-38kV
  • 630-900A continuous
  • 12.5-25kA fault interrupting
  • integral ground positions
  • sealed dead-front SF6
Overview

The TFI, TVI, TNI and GNI models round out G&W's gas-insulated line by combining load break switching and fault interrupting with integral ground positions - on the switch ways, the interrupter ways, or both. Rated 15.5 to 38kV with up to 25kA interrupting, they let utilities switch, protect and ground underground circuits from a single sealed dead-front unit.
