| Features of HS-X |
 |
- The device is designed for de-SF6 gassing (the first 24/36 kV in
the world) using insulation barriers at important places by applying
appropriate pressure of dry air.
- No need of SF6 gas recorvery.
|
 |
- Drastic reduction of width through triangular arrangement of vacuum
valves (VST) and effective design of insulation barrier.
- Realization of compactness through adoption of solid insulation
bus.
|
 |
- Maintenance-free operating mechanism for over 15 years through adoption
of long-life grease NiP (nickel-phosphor) plating
|
 |
- Reduction of weight by half (as compared with the conventional device)
and adoption of re-usable BMC (Bulk Mold Compound) insulation material
for maintaining harmony with environment.
|
 |
- Housing the main circuit equipment in an enclosed container for
drastic improvement in environmental resistance.
- Simplified structure of VCB and DS operating mechanism, and optimum
design using CAE
