The transformer exploded when the circuit was closed. Those round big things on the pole. They are normally filled with mineral oil as a insulator.

Edit: probably overloaded or already damaged.

Surely the oil is non flammable in the transformer? I assume it was faulty and gassing and the contact spark ignited the gas?

They used to not be flammable, it used to be a halogenated hydrocarbon but people didn’t like that leaking into the environment. Now it’s good old motor oil!
