Outdoor Complete Switchgear Assembly (KRUN-E)
General information
Outdoor packaged switchgear units (KRUN-E) are designed for receiving and distributing three-phase AC electric power at a frequency of 50 or 60 Hz, at a voltage of 6 or 10 kV, in networks with an isolated neutral or a neutral earthed through an arc-suppression reactor.
They are used to equip switchgear at a voltage of 6 or 10 kV of packaged (block-type) transformer substations 35/6(10), 110/6(10), 110/35/6(10) kV of power systems, industrial and agricultural enterprises, or in stand-alone KRUN-6(10) kV units.
The KRUN-6(10) kV is assembled from individual KRUN-E cabinets, each of which houses the apparatus for one connection to the switchgear busbars.
KRUN-E cabinets are fitted with a vacuum high-voltage circuit breaker (type per project). Vacuum switching does not require sulphur hexafluoride (SF6), provides a large switching endurance and minimal maintenance.
Climatic design U1 or UKhL1 per GOST 15150-69. Cabinet degree of protection — IP44 (34) per DSTU EN 60529:2014. KRUN-E units comply with TU U 27.1-40132794-001:2016.
The external design and configuration for block-type substations are developed and manufactured to order; short-circuit currents and main-circuit ratings are determined by the project / technical specification.

Description and purpose
KRUN-E is an outdoor complete switchgear assembly rated at 6 or 10 kV: an insulated metal enclosure with a vacuum high-voltage circuit breaker, designed to receive and distribute electricity in the open air, without a separate building. It is used as part of complete transformer substations (KTP) rated 35/6(10) kV and 110/6(10) kV, in overhead-line sectionalizing distribution points, at quarries and construction sites. The enclosure has a roof, a reinforced structure, heating, and an IP44 (34) protection rating. LK Energy Group is a switchgear manufacturer from Odesa, in business since 2005, with its own factory since 2015: we design and manufacture KRUN-E to your technical specification. Ratings and configuration are selected to match the project.
