GN30-12 indoor rotary high voltage disconnector is a new type with rotary knife. The main structural formula is to fix two sets of insulators and contacts on the upper and lower planes of the three- -phase common low frame, realizing the opening and closing of the switch by rotating the knife. GN3-12D switch adds a form of connecting knife on the basis of GN30-12 to meet the needs of different power systems. This product is compact in design, small in space, strong in insulation, easy to install and adjust. It meets the requirements of "AC high voltage isolating switch and earthing switch", and is applicable to indoor systems with rated voltage up to 10 KV AC 50 Hz and below. It can be used as opening and closing circuit when there is voltage and no load. It can be used with high voltage switchgear or can be used alone.
GN30-12 (D) type rotary indoor high-voltage disconnect switch is a new type isolation switch of rotary knife type, the main structure is fixed two groups of insulator and contact on the two plane of three-phase chassis, through the rotary contact, realize the switch on-off. GN30-12 (D) type switch is a new type added grounding knife on the GN30-12 type switch basis, which can meet the needs of different power systems. The product design is with compact, small occupied space, strong insulating ability, easy installation and adjustment, its performance meets the GB1985-89 "AC high voltage isolating switch and the grounding switch" requirements, applicable to the rated voltage 10kV AC 50Hz and below indoor power system, to open and close the circuit when voltaged, no load. It can be used with the high voltage switch cabinet, and also can be used separately.
GN30-12 isolating switch features
1. It is made of ceramic insulators, durable, pollution-resistant and no-cleaning.
2. Using new technology silver brazing contacts, low contact resistance, good electrical conductivity and high mechanical strength.
3. High-quality hardware, sturdy and durable, not easy to damage, easy to use and lightweight.
