KYN-61-40.5

Switchgear cabinets with a withdrawable circuit breaker

35 kV metal-clad switchgear cabinets: the compartments of the withdrawable vacuum circuit breaker, busbars, cable connections and relay protection are separated from each other. Used in 35 kV switchgear of substations and industrial sites.

Block-type outdoor switchyard (ORU)

Outdoor switchyard from factory-built blocks

The outdoor switchyard is assembled on site from ready-made blocks on steel frames: circuit breakers, disconnectors, current and voltage transformers. The blocks are made and checked in the workshop, which shortens installation on site.
