How much copper is inside a transformer?
Rahangdale says, In a typical large transformer, 50% of the cost is in materials.
Of that, about 15% to 20% is for copper and an equal percentage is for steel structural members and core laminations with the remainder in oil, insulation and the rest..
Are transformers dangerous?
Transformers are safe but can be a potential danger if they become damaged such as when they fall prey to vandals or landscaping equipment.

Pad-mount transformers are (nearly always) oil-filled units and so must be mounted outdoors only. The core and coils are enclosed in a steel oil-filled tank, with terminals for the transformer accessible in an adjacent lockable wiring cabinet.

What does a transformer look like?
A transformer keeps wired doorbells powered at the right voltage for optimal operation. It looks like a small metal box and can be silver, off-white or even brass colored.
Why do transformers explode?
Electrical transformers transfer energy between circuits, switching energy from one voltage to another. But when flooded with too much electricity, the sudden surge can cause a transformer explosion. … Older transformers can explode when their insulating materials begin to fail.
What liquid is inside a transformer?
Transformer oilTransformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.
