The KYN28-12(GZS1) Removable AC Metal-clad Switchgear(hereinafter referred to as “switchgear”) is suitable for three-phase AC 50Hz power system. It is used for receiving and distributing electrical energy and controlling, protecting, and monitoring circuits.
The newly introduced high-current, high-breaking switchgear can also be used independently for high-voltage generator outlets. This product complies with the standards: GB3906 “3~35kV AC Metal-Enclosed Switchgear,” IEC60694&GBT11022 “Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards,” IEC62271-200″ AC Metal-Enclosed Switchgear and Control Equipment with Rated Voltages Above 1 kV up to and Including 52 kV.”
Ambient Condition:
AmbientAir Temperature: Maximum temperature +40°C, Minimum temperature-15°C
Humidity Conditions:Daily average relative humidity:≤95%，Daily average water vapor pressure does not exceed 2.2kPa, Monthly average
relative humidity:≤90%，Monthly average water vapor pressure does not exceed 1.8kPa
