Gas Insulated SwitchgearCompact, 3-phase enclosed Gas Insulated Switchgear
Main features
The GT01 type SF6 Gas Insulated Switchgear (GIS) is a three-phase enclosed compact design, including the following main equipment: puffer assisted self-blast circuit breaker with spring drive, combined disconnector and earthing switch with motor drive, high speed earthing switch with motor charged spring drive, current and voltage transformers and surge arrester. The enclosure is made of corrosion-resistant aluminium alloy in welded or in casted construction. The current carrying tubes are aluminium tubes silver plated on the connection surfaces and fi tted into silvered contacts. For supporting the current carrying tubes and for terminating the independent gas compartments, epoxy resin insulators are used. Sealing is ensured by well-proven special „O” ring system, which gives an excellent gas tight-ness in case of indoor and outdoor installation as well.
General features of GT01 type compact GIS > modular system to fulfi ll user requirements > complete 3-phase enclosed construction and compact design
ensuring reduced space requirement > aluminium enclosures result low enclosure losses, light weight
and prevention of corrosion > the actual position of the moving contact in the disconnector
and earthing switch can be easily checked visually, through an inspection window
> low maintenance requirement, high availability and long service life > the thermo-dilatation and installation tolerances are compensated
by expansion joints > protection against dangerous over-pressure through
bursting membranes > completely assembled and factory tested bays can be delivered
for installation on site > suitable for indoor and outdoor installation
