37.5kva Single Phase Pole-Mount Transformer Oil Immersed Electricity Distribution13.8kv To 240v
The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, sup porting 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.
