New IEEE Standard – Inactive – Superseded. SUPERSEDED BY SH/SS95006 NOT AVAILABLE TO RESELLERS This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers. Electrical, dimensional, and mechanical characteristics and certain safety features of single-phase, 60 Hz, mineral-oil-immersed, self-cooled, distribution transformers with separable insulated high-voltage connectors are covered. Ratings, testing, and construction are discussed. These transformers are generally used for step-down pruposes from an underground primary cable supply and are suitable for occasional submerged operation. The intent is to provide a basis for determining their performance, interchangeability, and safety, and for their selection. This standard does not cover the electrical and mechanical requirements of accessory devices that may be supplied with the transformer You will receive an email from Customer Service with the URL needed to access this publication online.
