Solid-Insulated Switchgear (SIS) is an advanced medium-voltage (MV) power distribution solution that utilizes solid dielectric materials for insulation instead of SF₆ gas or air. Designed for 3.6 kV to 40.5 kV systems, SIS combines the compactness of GIS with the environmental safety of dry insulation, making it ideal for modern, sustainable electrical networks.
✔ Eco-Friendly – Eliminates SF₆ gas, reducing greenhouse gas emissions and regulatory concerns.
✔ Compact & Lightweight – 30-50% smaller than AIS, suitable for space-constrained installations.
✔ Maintenance-Free – Hermetically sealed with solid insulation, resistant to humidity, dust, and corrosion.
✔ Enhanced Safety – No risk of gas leaks, with superior arc-flash protection.
✔ Smart Grid Ready – Compatible with IoT sensors for real-time monitoring and predictive maintenance.
