75kva Oil Single Phase overhead Pole Mounted Distribution
Transformer 4160GrdY/2400 To 120/240V
The transformer is cylinder sealing structure.Each one is fixed
with grounding devices,hooks,supporting lugs which conforms to ANSI
standard,and one or two high voltage bushing on the cover,low
voltage bushing on the wall of the tank and eyebolt, connecting
terminals.The tap changer should be adjusted basing on the
instruction after the power off.
