HINDHIVAC Vacuum Impregnation Systems are
designed to impregnate electrical winding of
transformers, waters & coils of various other electrical
items for improving their insulation value and their
quality.
The Vacuum Impregnation Systems have an Impregnation chamber
which has a vacuum
sealed vessel made of mild steel with an internal diameter of
500 mm and depth of 650 mm with both top and bottom as
dished ends. The top dished end is detachable for
loading and unloading of the components meant for
impregnation. This has a viewing window, air admittance
valve, vacuum dial gauges and a light port. The top lid
can be moved in and swiveled out with the help of a
Davit-arm. The chamber is jacketed filled with oil and
inserted with oil immersion heaters of 1 KW each and are
immersed in the oil for heating. Glass wool insulation
for the oil heating chamber and cladding with sheet metal
to minimize heat loss.
The Impregnate Tank in the Vacuum Impregnation System is also a mild steel fabricated
chamber and is housed below the main chamber and is
connected to the impregnation chamber with a vacuum
tight pipeline. In another type Impregnation tank is
kept to the side of the impregnation storage chamber and
connected each other through a vacuum tight pipe line.
The phosphor bronze ball valve with a stainless steel
ball and Teflon seat is used for connecting both the
vessel and for driving impregnate into the Impregnation
chamber.
A specially designed control unit is located on the
front panel of the structure where the main chamber is
situated.. The frame designed and fabricated with
angular iron structure provides ample space to
accommodate accessories and gives large elbow room for
easy service and maintenance. This plant is assured to
give a vacuum of 0.01m.bar or better under clean empty
and thoroughly degassed chamber conditions.
