SECTIONER OR SWITCHERS ON-OFF

 SECTIONER OR SWITCHERS ON-OFF

The sectioner or switch ON-OFF is used to energize or de-energize the pedestal type transformer or the maneuver box. It’s a device used in the radial pedestal type transformers and it is placed in series with the winding and the high voltage insulators. Externally it has an actioner knob which is placed in the high voltage compartment.
It accomplish all the requirements of the norm ANSI/IEEE standard C 37.71 y c 37.72.
