Product Description

WSTII63/10-6× 5 Off-circuit Tap-changer with Strip Type

Introduction
This instruction is the brief introduction of the strip off-circuit tap-changer. The flange and lifting board of it are
fixed on the transformer cover, the function for the tap-changer is that we can operate the tap-changer on the
transformer cover, by regulating the tap position to realize the voltage regulating of transformer as required. But
only after the transformer is cut off from the electrical network, when the transformer is under off-circuit
State, could we operate this type of tap-changer.

If the tap-changer has oil leakage phenomenon, you must check the leakage position first, if the leakage is from
the turning axle, please screw up the plug on the axle, if the leakage is from the tank cover, you should screw
up the solid nut on the flange.
