KYN28‑24 Indoor Draw‑out Armored AC Metal‑Enclosed High‑Voltage Switchgear, 24kV

The KYN28‑24 armored removable AC metal‑enclosed switchgear is indoor high‑voltage switch cabinet, designed for three‑phase AC 50/60Hz power systems with rated voltage of 24kV.
It is widely deployed in power plants, substations, mining factories and high‑rise buildings, to receive, distribute electric energy and realize circuit control, protection & real‑time monitoring.
Full anti‑misoperation interlock functions are equipped: preventing moving‑cart operation under load, forbidding breaker closing while earthing switch is on, avoiding earthing‑switch closing on live circuits and blocking unauthorized access to live compartments.
This switchgear supports VS1, VN2 mid‑mounted vacuum circuit‑breakers and encapsulated vacuum switches. Bus‑bars adopt heat‑shrinkable tubing or epoxy‑coated insulation to optimize electrode performance. With compact layout, easy‑operation design and stable performance, it delivers high‑safety indoor power‑distribution.
