Sinlge Phase Pole Mounted Transformer Structural Features
1. The tank lids have high-voltage porcelain bushings that come
with ring terminals, which can accommodate either aluminum or
copper cables.
2. The circular sewing structure of the tank cover ensures even
stress distribution and reliable sealing.
3. The ring bolts on the tank wall serve as the low-voltage bushing
and terminal and are tin-plated.
4. This item comes with a pressure relief valve that is capable of
self-sealing.
5. According to ANSI standards, the transformer's suspension hooks
at the top and bottom comply.
6. The ground terminal on the tank is a ring bolt ground terminal.
