The circularity of medium-power electrical transformers

Bruno De Wachter

Abstract

The Design-for-recycling of mediumpower transformers is complicated by their long lifetimes. What will the recycling markets and technologies look like 50 years from now? We must be content with basing longterm predictions on the presentday situation. The Copper Alliance conducted an in-depth survey of the current state of transformer recycling. With their high metal content and
straightforward disassembly, liquidfilled transformers score highly in terms of circularity. This can be further enhanced by using copper for transformers are a different story; the lack of separability leads to a problematic end-of-life process.

Keywords

recycling, design-for-recycling, circularity, copper windings, dry-type transformers
