APPLICATION
Oil Circulation in the following :- power
transmission, distribution and electric traction
locomotive transformers.
DESIGN
The static transformer axial ‘IN-LINE’ pump is
basically a Centrifugal pump with a driving motor
assembly as a single unit on a common shaft.
The transformer oil circulates through the
windings thus eliminating any seal shaft and
avoiding the danger of oil leakage or entry of air.
The in-line arrangement allows for the direct
mounting in a horizontal or vertical position with a
flow directed either way with the advantage of
being compact.
The static transformer 'ELBOW' pump is basically
a pump with a driving motor assembly as a
single unit on a common shaft. The transformer
oil circulates through the windings thus
eliminating any seal shaft and avoiding the
danger of oil leakage or entry of air. The
complete unit can be arranged for horizontal or
vertical mounting with a variety of discharge
branch positions based on end suction and side
discharge.
