GN30‑12 Indoor Rotary High Voltage Disconnector | 12kV Rotary‑blade Disconnector
Overview
GN19‑12 series indoor high‑voltage disconnector belongs to high‑voltage switchgear equipment. It is applied in power systems with rated voltage 12 kV, AC 50 Hz and below. Fitted with CS6‑1 manual operating mechanism, it is used for circuit opening and closing under live‑voltage yet no‑load condition. Anti‑pollution type, high‑altitude type and version with live‑line indicator are available as optional variants.
Environmental Conditions
- Altitude: not exceeding 1000 m.
- Ambient air temperature: -25 °C ~ +40 °C.
- Ambient relative humidity: daily average ≤95 %, monthly average ≤90 %.
- Seismic intensity: not exceeding Grade 8.
- Installation site: free from fire hazards, flammable‑explosive substances, heavy contamination, chemical corrosion and severe vibration.
