Product Overview
The GN30-12 type indoor rotating high-voltage isolating switch is a new generation isolating switch with a rotary touch cutter. The GN30-12 features a design that fixes two pairs of insulators and contacts on the upper and lower planes of the three phases with a common bottom frame. By rotating the contact knife, the GN30-12 efficiently achieves the opening and closing of the switch, ensuring stable and reliable high-voltage isolation performance.
Type and meaning
On the basis of GN30-12 type indoor rotating high voltage isolating switch, the GN30-12D type indoor rotating high voltage isolating switch adds the form of the contact knife, which can meet the needs of different power systems. This product is compact in design, small in footprint, strong in insulation and easy to install and adjust. Its performance accords with the requirements of the national standard GB1985-89 AC High Voltage Isolating Switch and Earthing Switch, suitable for the indoor system with rated voltage of 10kV, AC 50Hz and below, can be used to open and close circuit under the condition where there is a voltage without a load. It can be used in conjunction with the high voltage switchgear and can also be used alone
