Indoor AC metal armored withdrawable switchgear

KYN28-12 indoor AC metal armored withdrawable switchgear is designed by Shuangying Electric for modern power Advanced power distribution equipment created by the system. It is designed to meet the needs of power plant transmission, power system, and industrial and mining enterprise substations The goal is to meet the demand for power supply and distribution, with multiple functions such as control, protection, and frequent starting of high-voltage motors. The switchgear is designed strictly in accordance with the "five prevention" interlocking requirements, greatly reducing the risk of misoperation and ensuring the safety of equipment and personnel Employee safety. Extremely flexible in circuit breaker configuration, it can be equipped with ABB's VD4 vacuum circuit breaker The circuit breaker can also be selected from domestic VS1 vacuum circuit breakers, providing users with diverse choices.
