Detailed Instruction

1. Overview

GN30-12 / 630 isolatiion switch is a rotary touch knife type of new isolation switch, the main structure is in the three-phase under the base frame, the next two planes, fixed two groups of crepe and contact, by rotating the touch knife , In order to achieve the switch off the closing.
GN30-12 / 630 isolation switch (indoor AC high voltage disconnector) for rated voltage 10kV, three-phase AC 50Hz power system as a voltage without the case of load, the use of sub-electrical appliances.
GN30-12 / 630 isolation switch to meet the needs of different power systems, the product design performance is excellent, small footprint, strong insulation. Easy to install the adjustment, its performance in line with GB1985-89 "AC high voltage disconnector and grounding switch" requirements for rated voltage 12 kV AC 50Hz and below indoor power system, as in the case of voltage without load, Circuit use. Can be used with high-voltage switchgear, can also be used alone.The performance of this product in line with "AC high voltage disconnector and grounding switch" standard.
