KSO series single-sided Service Prefabricated Chambers

The chambers are intended for installation in closed electrical rooms. Climatic version type – UHL according to GOST 15150. The diagrams of the main circuits of the KSO chambers are given in Appendices A, B and C. The overall dimensions of the KSO chambers are given in Appendix G. The list of KSO chamber types is given in Appendix D. The list of devices and equipment required for monitoring and testing of KSO chambers is given in Appendix E. The list of documents referenced in these technical conditions is given in Appendix G.

The structure of the conventional designation of the type of KSO chambers using the example of an input chamber according to the main circuit diagram 5 with a VPMP-10 switch and a PPO-10 drive for a rated current of 600 A has the following form:

KSO-285-5PV-600 UHL3.1, where KSO is a one-way service assembly chamber; 285 is a modification of the chamber (285 – 1985, 292 – 1992, 298 – 1998, 366 – 1966, 386 – 1986, 393 – 1993);

5 – serial number of the main circuit diagram; PV – switch type (PV – VPMP-10 switch with PPO-10 drive; E – VPM-10 switch with PE-11 drive); 600 – rated current of the chamber (400, 600 or 1000 A); UHL3.1 – climatic version and placement category.

By special order, KSO chambers can be manufactured for a lower ambient air temperature of down to minus 45° C, and the order form must be as follows: "KSO-285-5PV-600 UHL3.1, TU 3434-006-971054348-2009, minus 45° C". General requirements - KSO chambers must comply with GOST 14693, the requirements of these technical conditions and a set of design documentation approved in the established manner.
