This indoor, metal-clad AC switchgear — built on the KYN28 intermediate-type platform with a withdrawable design — targets medium- and high-voltage distribution in substations and industrial plants. Spanning 10kV to 33kV at 4000A and housed in an IP65 stainless steel enclosure, it gives main switchboards and distribution systems compartmentalized, safely isolated switching and protection.
Fits indoor high-voltage distribution rooms, substations, industrial power supply systems, and utility main switchboards operating anywhere from 10kV to 33kV.
Protection level (IP30–IP66), cabinet color, voltage/current rating arrangement, and internal wiring scheme can be tailored to the project at hand.
Before ordering, please confirm the rated voltage, rated current, protection level, and circuit scheme needed.
Spans a broad voltage range: 10 / 11 / 20 / 24 / 33 kV; Carries a 4000A rating suited to demanding main switchboard applications; Metal-clad, draw-out construction that simplifies isolation and upkeep.
