Prefabricated single-front-access switchgear cubicles, type KSO-E (size 219)
General information
KSO-E (КСО-Е) Single-Front Assembled Switchgear Cells
KSO-E cells are designed for the reception and distribution of three-phase alternating current electrical energy at 50 Hz in networks with an isolated neutral or a neutral grounded through an arc-suppression reactor. LK Energy Group manufactures KSO-E cells for 6 and 10 kV as a standard product; versions for 20 and 35 kV are available to order according to technical specifications (short-circuit currents and ratings for these classes are determined on a project-specific / TOR basis). Switching — vacuum; no SF6 gas-insulated version is available. Enclosure — a riveted assembled structure made of galvanised cold-formed profiles, with optional RAL powder coating.
The cells are equipped with main devices and protection elements according to the ordering scheme; secondary wiring diagrams are developed for each individual project. Manufactured in accordance with TU U 27.1-40132794-002:2016.

Description and purpose
KSO-E are prefabricated, single-front-access switchgear cubicles for 6 and 10 kV indoor switchgear installations (indoor switchgear/indoor transformer substations). Switching is performed by fixed-mounted vacuum circuit breakers and disconnectors; no SF6 (gas-insulated) design is offered. They are designed for the distribution boards of industrial facilities, transformer substations and central distribution substations — for receiving, metering and distributing electricity with frequent switching operations. Suitable for designers, contractors and industrial customers. LK Energy's advantage is its own production of switchgear equipment in Odesa since 2005: cubicle ratings and single-line diagrams are manufactured to the customer's project or technical specification, complete with installation and commissioning.
