KYN28-12(GZS1) type armored removable AC metal-clad switchgear (hereinafter referred to as "switchgear") is suitable for three-phase AC 50Hz power systems, used for receiving and distributing electrical energy, as well as controlling, protecting and monitoring circuits. This newly introduced and developed high-current, high-breaking switchgear can also be used independently at the outlet of high-voltage generators.
This product complies with the following standards:
GB3906 "3~35kV AC Metal-Clad Switchgear"
GB/T11022 "Common Technical Requirements for High-Voltage Switchgear and Control Equipment"
IEC298 "High-Voltage Switchgear and Control Equipment with Rated Voltages Above 1kV and Up to and Including 52kV"
