General information
KM-E — complete switchgear (KRU, КРУ) 6/10 kV
KM-E cabinets (series KM-1F) are designed for receiving and distributing three-phase 50 Hz AC electricity at 6 or 10 kV in networks with an isolated neutral or a neutral grounded through an arc-suppression reactor. Switching is vacuum-type (LK Energy Group does not use SF6 gas). Structurally, it is a riveted metal construction made of galvanized steel with front-access service; the cabinet is divided into compartments for busbars, the withdrawable element, and the cable inlet; the RPA (РЗА) compartment is located at the top of the front panel.
The withdrawable element carries the vacuum circuit breaker, voltage transformers, or an auxiliary supply transformer; the cable compartment houses current transformers and surge arresters. The secondary circuit schemes are based on microprocessor-based protection relays, project-specific. Operational interlocking is implemented per DSTU EN 62271-200:2015. Manufactured according to TU U 27.1-40132794-001:2016.

Description and Purpose
KM-E is indoor complete switchgear (KRU) rated for 6 and 10 kV voltage with a vacuum circuit breaker on a withdrawable (cassette-type) element. It is designed for receiving and distributing 50/60 Hz electric power in indoor switchgear (ZRP) at regional power utility (oblenergo) substations, industrial facilities, oil and gas sites, and CHP plants with frequent switching operations. It is manufactured by LK Energy Group, a switchgear manufacturer based in Odesa, in business since 2005, with its own factory since 2015, in compliance with TU U 27.1-40132794-001:2016 (Ukrainian technical specifications) and DSTU IEC 62271-200:2015 (Ukrainian national standards). Current ratings, main circuit schemes and cabinet configurations are selected to match your project and single-line diagram.
