General FeaturesWorldWide experience and perFormanceSince 1905, G&W has been provid-ing custom electrical products andinnovative solutions to power usersaroundtheworld. Today,G&Wcon-tinues that traditionwitha full lineofsolid dielectric switchgear using theindustry’slatestinsulationtechnology.Tridentswitchgearcombinesthebestsolid dielectric insulation materialswithtimeproven,rugged,andreliableswitchingdesigns.Drawingonmanyyearsoffieldexperienceintheareasof loadbreak switchingand vacuumfault interrupter technology,G&Wof-fers one of the widest selections ofelectrical distribution switchgear intheindustry.

solid dielectric technoloGyTrident switchgear utilizes G&W’stimeproven,submersibleepoxypoly-mer system to fully encapsulate thevacuum interrupters. This systemprovides excellent insulation proper-ties and incorporates a permanentlybonded semi-conductive externalcoating providing a fully shielded,void-free construction. Internalshieldslimittheelectricalstressintheepoxy,thereforeincreasingitselectri-cal integrity. All modules are 100%factory tested for partial discharge.Dual ratio current transformers areencapsulated within each moduleprovidingeither500:1or1000:1pro-tectioncharacteristics.

submersibilitySolid dielectric switchgear is dead-front and fully submersible. Unitshave remained fully operable afterwithstanding years of submersion atdepthsofupto10feet(3m).

Installation shows a 3-way switch, frame mounted so the unit faces upward with side operating handles hookstick operable from above ground. The location is subject to complete submer-sion for extended periods of time. The yellow cable is con-nected to a laptop computer permitting programming of the overcurrent protection parameters for the switch.

Trident-SP single phase, spring-assisted switchgear is availablefor load break or fault interruptingswitching. The compact units areideal for switching residential loopsand for oil fuse cutout replace-ments.
