Gas Insulated Switchgear (GIS) is a kind of metal enclosed switchgear which is used in the control and protection of the electrical transmission and distribution systems. Components like Circuit Breaker, Disconnector, Earth switch, Current transformer, Bus Duct are enclosed by gas tight metal enclosure and SF6 gas is used as insulation between live parts of the equipment and earthed metal enclosure. The product ranges from low voltage to ultra-high voltage.
| Rated Voltage (kV) | 145 |
| Rated Current (A) | Upto 3150 |
| Rated Frequency (Hz) | 50 |
| Rated Short time withstand Current and duration (kA/s) | 40/4 |
| Key Features | 1. Compact in Size. 2. Reliable making and breaking capabilities even under extreme environmental condition. 3. Excellent interrupting performance at rated nominal current and rated short-circuit current. 4. Enclosed Design. Being fully encapsulated shields live equipment against environmental stresses. 5. Long Lifespan. High performance. 6. Very high degree of Gas tightness. 7. Easy access for installation and maintenance. |
