Introduction:
HKA-24 Metal-clad Enclosure Switchgear is advanced high-voltage switchgear that Beijing Huadong Electric Co., Ltd. has independently worked out and developed. It applies to the electric power system of 3 phase AC 50Hz. It is mainly used to receive, distribute the electric energy as well as control, protect and monitor the circuit.

HKA-24 Switchgear boasts various ways to prevent misoperation, including preventions on movable truck and earthing switch under load operaion, on the closing of earthing switch at the closing position of breaker.

HKA-24 Switchgear is equipped with withdrawable VD4, VH4 or SF6 breakers of high performance. The secondary loop of the switchgear is fixed with advanced and reliable protective components. HKA-24 Switchgear is a power distribution equipment, combining high technology, stable performance and reasonable structure. It is easy to use, safe and reliable

Introduction of Standard and Criterion:
HKA-24 Switchgear is designed and made according to the following standards:

International Electrotechnical Commission Standard.

IEC62271-200 rated voltage (more than 1KV and less than 52KV) AC metallic enclosure switchgear and control equipment.

IEC60694: 2002 common technical requirment for high-voltage switchgear and control equipment.
