K-MVS-H – Integrated Switchgears
Description
К-MVS-H type integrated switchgears are intended to receive and distribute three-phase AC (50 Hz, 6 (10) kV) electrical power.
An integrated switchgear of К-MVS-H type is enclosed into a SF6-filled metal case in a seal welded container for the entire service life of 30 years, that accommodates vacuum disconnect switches, three-position disconnect switches or load breakers. К-MVS-H has successfully passed all type tests and certification to Russian regulations.
К-MVS-H type integrated switchgears are used as switchgears for electrical stations, transformer substations and power distribution stations in various industries.
Advantages:
-
No contact with live parts
-
Maintenance-free throughout its service life (for at least 30 years), enabling the user to cut operating expenses significantly
-
Ease of operation and reliability
-
Minimized dimensions of the K-MVS-Н switchgear due to small-sized cubicles
-
Insensitiveness to harsh environments or severe climates, i.e. dust, contamination, high humidity and mist (up to 98%). Insensitive to condensate
-
No handling sulfur hexafluoride throughout service life, including during installation or upgrade
-
No draw-out elements
