25kva Oil Immersed Distribution Transformer Single Phase Pole Mounted Transformer
Standard Feature
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.
