Why is a Toroidal Transformer "GREENER" than a conventional laminated transformer?
There are several factors that make the toroidal transformer an advantageous choice compared to laminated transformers when impact on environment is a consideration:
1) A toroidal transformer weighs about half as much as a conventional transformer with the same capacity and heat rise. The main materials used in transformers are copper and steel, both of which are getting scarcer with cost increases as a consequence. We will explain how the weight savings can be explained in a separate newsletter.
2) No impregnation is needed to keep the laminates quiet so this potential environmental hazard is avoided.
3) The toroidal transformer fits into a smaller space, which allows chassis plates and enclosures to be smaller with less material used.
4) The lower weight reduces the cost and lessens the environmental impact of freight for raw material coming into our factory, transformers sent from us to you and outgoing freight for finished product from you to the end customer.
5) There is a much more efficient trade-off between size and temperature rise with a toroidal transformer when compared to a laminated transformer.
A toroidal transformer designed to run cooler will only be slightly larger than a "conventionally" designed transformer and will increase the overall efficiency of the equipment, lower demand for cooling in the equipment and increase the life span of other components in the equipment.
How lower operating temperature can more easily be achieved in a toroidal compared to an old-fashioned laminated transformer will be explained in a separate newsletter. |
