Introduction:
The Transformer vacuum maintenance plant consist of a mechanical booster pump, in conjunction with a rotary gas ballasted back up pump.
Model ZLH vacuum transformer vacuuming plant is equipped with an electrically operated safety valve which at current failure or switching off of the plant automatically prevents an in-rush of air onto the degassifying chamber but admits air to the vacuum pump so that no pump oil can rise in the vacuum pipe line.
