Overview
Solid Insulated Switchgear (SIS) replaces traditional gas insulation with epoxy-resin-encapsulated components, eliminating greenhouse gases while delivering superior performance in 12–40kV networks. By embedding live parts in maintenance-free solid dielectric, SIS achieves ultra-compact dimensions, immunity to environmental contaminants, and >30-year lifecycle reliability. Compliant with IEC 62271 standards, it’s the go-to solution for decarbonizing power infrastructure without compromising safety or space efficiency.
Product Features
1. Hermetically Sealed Insulation System:
High-voltage load switch and live components are encapsulated within epoxy resin insulating enclosures, achieving complete gas-free operation.
Vacuum interrupter technology ensures reliable arc extinction within a space-optimized design.
Integrated load switch features a three-position (Make-Break-Earth) mechanism with grounding functionality.
The earthing blade serves dual-purpose as an isolation barrier.
Units support modular expansion via three-pole shielded solid-insulated bushings per circuit for cable termination.
Engineered sealed housings (import-grade) ensure hermetic integrity at mechanism-bushing interfaces.
Bushings and insulation cylinders utilize imported cycloaliphatic epoxy resin, fabricated via Automated Pressure Gelation (APG) technology.
Silicone rubber sleeves provide compression sealing between insulation cylinders and high-voltage bushings.
Each circuit features dedicated front-mounted operating mechanisms with comprehensive mechanical interlocks.
Spring-operated mechanisms drive both load switch (manual/electric operation) and earthing/isolation switch (manual-only).
Configurable with permanent magnet actuators (PMA):
Electric closing/opening
Manual tripping only (no manual closing)
Spring-operating mechanism alternative:
Manual/electric operation
Pre-wired terminal block for distribution automation integration
Challenge: Space-constrained city centers needing SF₆-free gear to meet air quality mandates (e.g., London LEZ).
SIS Role:
Zero-gas design eliminates F-gas reporting/taxes (EU 517/2014).
40% smaller footprint vs. AIS enables installations in basements/car parks.
IP67-rated solid barriers prevent flashovers in polluted/damp environments.
Challenge: Strict PUE targets and zero-tolerance for SF₆ leaks near critical IT loads.
SIS Role:
SF₆-free insulation aligns with RE100 commitments (Google/Amazon).
Fire-resistant epoxy (V0-rated) eliminates arc-flash propagation risks.
-40°C to +65°C operation ensures stability in server-farm microclimates.
Challenge: Conductive dust/corrosive vapors degrading conventional switchgear.
SIS Role:
Hermetically sealed modules block salt, sulfide, and metal particulates.
Seismic resilience (IEC 62271-3 Class 2) for vibration-heavy zones.
No SF₆ gas monitoring → 35% lower OPEX vs. GIS.
Challenge: Salt spray/100% humidity triggering insulation failures.
SIS Role:
Corrosion-proof encapsulation survives ISO 9227 salt-mist testing.
Pressurization-free design avoids explosions at sea level/altitude.
Shock/vibration resistance for floating solar/wind installations.
Challenge: Vital infrastructure needing fire-safe, non-toxic gear.
SIS Role:
Zero-toxicity decomposition (even during arc faults).
Limited ventilation compatibility for underground deployments.
Passive cooling operation removes HVAC dependency.
