Pole Transformer Tank Rust.

I noticed a grey painted pole mounted transformer today. The cooling oil tank and one side of the transformer was very rusty. Just what is the metal thickness of the cases of these transformers? When will it rust through and spill its cooling oil?

  • It is very rare for them to rust enough to leak. If it does leak, it might go up in flames inside, but not much change outside except popping the HV protection. Modern oil is not too environmentally dangerous. The thickness is at least 3mm probably more.
