GN19-12

INDOOR HIGH VOLTAGE
ISOLATING SWITCH

Overview
GN19-12 series indoor high-voltage isolation relation high-voltage switchgear, used in rated voltage 12kV, AC 50Hz and below power systems, equipped
with CS6-1 human-operated mechanism, as a voltage without load, For the purpose of splitting and combining circuits, there are also derivative
products of anti-fouling type, high-prototype, and the installation of charged display devices.
