Prefabricated single-front-access switchgear cubicles, type KSO-E (size 219)
General information
KSO-E (КСО-Е) Single-Front Assembled Switchgear Cells
KSO cubicles in Ukraine are built by LK Energy Group: 6, 10 and 20 kV as standard; 35 kV to order. Frame 219 is the 6 and 10 kV version with a 600 mm front. Production — Odesa.
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, 10 and 20 kV as a standard product; versions for 35 kV are available to order according to technical specifications (short-circuit currents and ratings for this class 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 our own technical specifications.

Description and purpose
Frame 219 is the narrower version of the KSO-E series: the reduced-width cubicle measures 600 mm across the front, against 650 mm in frame 393. We do build this version — ratings and the single-line diagram are selected to the customer’s project or technical specification. It is chosen where the switchroom is tight and every centimetre of frontage counts: rated main-circuit current 630 / 1000 A — the same range as in frame 393. Rated voltage is 6 and 10 kV; 35 kV versions are built to order per the technical specification. Switching is vacuum; electrodynamic withstand of main circuits 51 kA, thermal withstand 20 kA for 3 s; at 10 kV — 63 kA and 25 kA.
The purpose, primary connection diagrams, series composition and applications are described on the main page — KSO-E cubicles, frame 393.
