Bucket-type transformers are typically oil-filled, using oil components to cool the interior. This type of transformer is generally used outdoors. The coil material inside bucket-type transformers can be either copper or aluminum. The outer shell is made of cast iron or stainless steel. Unlike three-phase transformers, bucket-type transformers often consist of a single winding set. The copper content is slightly higher than in ordinary transformers, around 28-30%. The copper winding can be considered as No. 1 copper quality, with dismantling costs of approximately 30-40 USD per ton.
Transformer heads and pole tops can contain over 10% copper, often with a copper plating. Transformers with a single winding set have slightly more copper, around 28-30%. The copper wire from the transformer can be sold as No. 1 copper wire, and the copper winding must be dismantled cleanly. Processing costs are approximately 30-40 USD per ton.
