500 kVA Transformer
Entry size for an industrial intake; often the first step up from a utility low-voltage supply.
A 500 kVA transformer is a three phase distribution transformer rated at 500 kVA, used to step medium voltage — typically 11 kV, 22 kV or 33 kV — down to a low voltage such as 400 V or 415 V for industrial and commercial distribution.
Entry size for an industrial intake; often the first step up from a utility low-voltage supply. Available in oil immersed and dry type construction, with copper or aluminium windings and ONAN, KNAN, AN or AF cooling depending on the installation.
