GN19‑12 Indoor High‑Voltage Disconnector

GN19‑12 Indoor High‑Voltage Disconnector

Overview

GN19‑12 series indoor high‑voltage disconnector is high‑voltage switchgear equipment applied in power systems with rated voltage 12 kV, AC 50 Hz and below. It is fitted with CS6‑1 manual operating mechanism, used for circuit opening and closing under live‑voltage but no‑load conditions. Pollution‑resistant type, high‑altitude type and variant fitted with live‑voltage indicator are also available.

Environmental Conditions

  1. Altitude: ≤ 1000 m
  2. Ambient air temperature: ‑25 °C ~ +40 °C
  3. Ambient relative humidity: daily average ≤ 95 %, monthly average ≤ 90 %
  4. Seismic intensity: not exceeding Grade 8
  5. Installation site: free from fire hazard, flammable / explosive substances, heavy pollution, chemical corrosion and severe vibration.
