In this video, we explain everything you need to know about Gas Insulated Substations (GIS) and why they are becoming the preferred choice for high-voltage networks.

✔ What is GIS? A substation design where SF₆ gas acts as the main insulating and arc-quenching medium.
✔ Why choose GIS?
• Dielectric strength nearly three times higher than air
• Superior arc-interruption capability
• Requires only 10–20% of the space used by an Air Insulated Substation (AIS)
• Fully sealed design that resists dust, moisture, and pollution
• Longer service life of 40–50 years with minimal maintenance
✔ Main Components of GIS:
• Gas-insulated busbars with disconnectors and earthing switches
• Gas-insulated circuit breakers with motor-charged spring operation
• Current transformers, earthing switches, lightning arresters, and cable terminations
• Gas management devices like density monitors, valves, rupture discs, and moisture adsorbers

This compact and reliable design makes GIS ideal for urban areas and harsh environments. Watch till the end to learn why GIS is the future of substations.
