KSMV Series

COMPACT MODULES

metal enclosed, SF6 gas-insulated

Compact modules series KSMA are intended for design of various compact, metal enclosed switchgear variants. All live parts are placed in SF6 gas-insulated steel containers, which provide mutual insulation of current path elements, as well as insulation to the earth level potential. Busbar compartments are also SF6 gas-insulated. The electric arc quenching takes place in vacuum interrupters built in circuit breakers and load break switches. SF6 gas is not used as arc-quenching medium, which provides complete environmental acceptability of this product and eliminates operational maintenance of the primary circuits.

Besides the obligatory manual drive, compact modules series KSMA are equipped with motor drive and set of releases for remote control of each device. This feature enables complete automatization of these switchgear type.

Compact modules series KSMA are built for indoor installation at normal service conditions, in accordance with IEC 62271-200. Nominal parameters of these modules have been confirmed by adequate certificates.
