KYN28-12 Indoor Metal-Clad Withdrawable Switchgear
For medium-voltage distribution rooms in power plants, industrial facilities, mining enterprises, substations and motor-control projects.
What it doesKYN28-12 is an indoor metal-clad withdrawable switchgear for 3.6-12 kV three-phase AC 50 Hz single-busbar or sectionalized single-busbar systems. It supports power receiving, distribution, control, protection, measurement and circuit monitoring.
Why buyers choose it- Withdrawable design helps inspection and maintenance without redesigning the whole switchroom.
- Rated voltage options cover 3 kV, 6 kV, 7.2 kV and 12 kV systems.
- Rated current up to 3150 A supports demanding medium-voltage distribution projects.
- Can be equipped with VD4 or VS1 vacuum circuit breakers according to project preference.
- IP4X enclosure and IP2X protection when compartment doors are open improve site safety.
Please confirm system voltage, rated current, short-circuit breaking current, busbar scheme, breaker brand preference, incoming/outgoing circuit quantity, protection relay requirements and project standard.
