Delta general purpose transformers CD6A series of aluminium wound transformers offer an economical alternative to copper wound transformers. Designed by Delta engineers through their specialized software, the compact Delta CD6A series aluminium transformer design require virtually the same floor space as comparable copper units and substantially less space than other manufacturer's aluminium products. The electrolytic coils are wound in a circular configuration to allow a uniform circulation of air for superior cooling and efficient operation. The high quality grain-oriented steel laminations ensure reliable sound levels. The CD6A series transformers employ the E.V.I. process which ensures structural mechanical strength, a better heat dissipation, improved resistance to humid, salty and corrosive environments, improved dielectric properties and lower noise levels. Our three-phase CD6A series transformers are manufactured to exacting standards and our quality assurance program complies with ISO standards and is available upon request.
