KYN28A-12 High Voltage Removable Switch Cabinet

Product Details

summary:

KYN28A-12 AC Metal Armored Removable Switchgear is a complete set of indoor switchgear for three-phase AC and 50Hz, rated voltage 3-12kV, single busbar and single busbar segmented system. It is mainly used for receiving and distributing electrical energy in power plants, substations, residential distribution, and distribution rooms of industrial and mining enterprises. It can also be used for starting control of high-voltage motors, and can achieve control, protection, and detection of circuits. The switchgear can be equipped with imported brand circuit breakers such as VD4, EV12, HVX, AV3, as well as domestic brand circuit breakers such as VS1, VEP, VBG, ZN73A.

This switchgear complies with standards such as GB3906-2006 "3.6~40.5kV AC Metal Enclosed Switchgear and Control Equipment", GB/T11022 "Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards", IEC62271:2000 "AC Metal Enclosed Switchgear and Control Equipment for Rated Voltage Above 1kV and Below 52kV", DL/T404 "Technical Requirements for Ordering Indoor AC High Voltage Switchgear", etc.
