Medium Voltage

General

SYStem 6 M.V. switchboard is composed by a standarized, modular and compact series of Metal Enclosed and internally arc-proof panels, equipped with SF6 insulated on-load switches and circuit breaker.

Complex switchboard configurations can be realized using the standard panels.

Each panel is equipped with mechanical interlocks and a movable mimic diagram, which grant the Maximum safety of operation.

Arc-proof execution allows to employ these panels even in extreme conditions.SYStem-6 switchboards are used in medium voltage secondary power distribution. In particular they can be used for transformer substation, for the lines control and protection and power distribution.
