TRIDENT® Solid Dielectric, Single Phase Switches and Fault Interrupters

Rated through 27kV, 630A continuous, 12.5kA interrupting.

Switches can provide both load break or fault interrupting operation. Fault protection can be provided using either fault interrupter relays or encapsulated current limiting fuses depending on the protection requirements.

Features:
	Latest Solid Dielectric Technology — Trident switches utilize G&W’s time proven EPOX technology quality system using Vantico Araldite CW 229 polymers. This system provides excellent mechanical and electrical insulation properties while assuring rugged, void-free, submersible construction. Other EPOX products include junction bars, encapsulated fuses and switchgear entrance bushings. A permanently bonded, external semi-conducting coating provides a fully shielded, deadfront design and allows 100% factory testing for partial discharge. The encapsulated internal shield forces all of the electrical stress into the epoxy material therefore the electrical integrity of the design does not depend on the ambient air.
	Maintenance Benefits — Solid dielectric insulation means no more oil, no more gas and no more air insulated concerns. That means no more routine switch maintenance.
	Application Versatility — Trident switches are compact, sub mersible and ideal for vault applications. Padmount designs permit a variety of bushing orientations for single side access or for separate compartments if desired. Operating handles can be orientated for side or front operation.
	Tested Reliability — Switches are designed and tested to applicable ANSI C37.71, ANSI C37.60, ANSI C37.72, IEEE 386, IEC 265, IEEE 592 and ANSI C119.4 standards.
	Mounting Flexibility — Switches can be mounted in any attitude to suit specific application requirements. Mounting brackets and straps are stainless steel for maximum corrosion-resistance. Parking stands are available.
	Spring Mechanism — Switches incorporate integral single phase or three phase spring mechanisms for positive open or close operation.
	Contact Position Indicator — Large viewing windows simplify visible verification of open (green) or closed (red) vacuum contact position. The position indicator is connected directly to the drive assembly.
	Electronic Trip And Cabling Options — For fault interrupting switches, a variety of electronic trip modules are available to match most common protection TCC curves. One option provides a single curve, single setting which eliminates the need for any external connector or cabling. Programming via laptop computer or built-in LCD display are also available options. Electronics are powered by CTs encapsulated inside the module. No external power is required.
	Cable Entrance Flexibility — Cable entrances can be either 200A deepwell or 600A apparatus style IEEE 386 interfaces for accepting elbow style connectors. The module orientation can be any 90° configuration permitting cable entry from the front, side or back of the unit. The rugged epoxy surfaces minimize the breaking force required for removing separable connectors compared to rubber-to-rubber junctions.
	Ordering Flexibility — Solid dielectric insulation permits modular construction. This means the user can specify the switch that best meets their application requirements. Start with a load break switch. Add a fault interrupting switch way if you wish. Single phase or three phase. Or maybe current limiting fuses. Need remote control? Add a switch module or fault interrupter with remote acutator. Choose from a variety of electronic control options. Whether it’s a padmount or vault application, front access or separate cable and operating compartments, you decide. G&W Trident switches provide an extremely flexible solution.
	Ideal replacement for oil fuse cutouts — Switches are compact and submersible. Type 5 relays provide single oil fuse cutout curve protection. The relay is mounted inside the mechanism housing and eliminates all external cabling.
