T – Load Break Switchgear with Integral Ground
G&W Electric T padmount and vault gas-insulated switchgear features load break switching capability with visible break and integral ground position in a totally sealed, dead front device. The integral ground position eliminates the need to handle any high voltage connections to ground the cable. The switches are designed for use on 3-phase systems with voltages up to 38kV, 630A load break and continuous current, and 40kA asymmetrical momentary ratings. They feature front access construction with switch operators on the front side and bushings on the front, top or rear side of the switch. The bushings are arranged in a straight line on the switch tank so that all the bushings are at the same height.
The switches are designed to IEEE C37.72 and C37.74 for load break capability. Padmount enclosures are designed and tested to IEEE C57.12.28 and C57.12.29.
Features and Benefits
-
Construction – In-line bushing construction for terminations with front accessible switch operators and bushings. Vault construction is also available with top or bottom bushings or top access to operators and bushings.
-
Ground Position – Integral ground position on all ways to eliminate the need to handle high voltage components to ground the cable.
-
Automation – Available for motor automation with portable or permanently mounted motor and controls. A variety of relays such as SEL, ABB, and GE are available with G&W Electric programming and cabinet construction. Cabinets can be ordered in a low voltage enclosure for padmount, pedestal or IP68 rated submersible for vault installed switchgear. Programming for automatic source transfer, or LaZer custom solutions are available.
-
Visible Break – All ways are equipped with visible break to view the open, closed and ground positions.
-
Voltage Sensing – Available integral voltage sensing for use with voltage indication panel to determine in-phase condition or for use with a relay with up to 1% accuracy.
