 Main features

The GT01 type SF6 Gas Insulated Switchgear (GIS) is a three-phase enclosedcompact design, including the following main equipment: puffer assisted self-blast

circuit breaker with spring drive, combined disconnector and earthing switch withmotor drive, high speed earthing switch with motor charged spring drive, currentand voltage transformers and surge arrester. The enclosure is made of corrosion-resistant aluminium alloy in welded or in casted construction. The current carryingtubes are aluminium tubes silver plated on the connection surfaces and fitted intosilvered contacts. For supporting the current carrying tubes and for terminatingthe independent gas compartments, epoxy resin insulators are used. Sealing isensured 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 fulfill user requirements

 > complete 3-phase enclosed construction and compact designensuring 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, throughan 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
