Single Phase Isolation/Distribution Transformers (Double Wound) Quick links: [Application] [Features] [Common Info] [Options]

Application Isolation Transformer defined: A transformer which isolates the primary circuit from the secondary circuit. An Isolation/distribution type Transformer should be used on all systems that require grounding of the load. Single Phase isolation/distribution type transformers are ideal for supplying auxiliary lighting circuits from 600V and lower supplies and electric heating equipment. Features    General purpose indoor ventilated steel enclosure (Nema-1 or CSA-1) suitable for dry locations. After fabrication, the enclosure is finished in ASA61 grey powder paint suitable for most industrial and commercial installations. Transformers up to 75KVA may be readily hung on H-columns, walls, shelves or floor mounted to suite each typical installation. Most units have lifting lugs, conduit knockouts and removable front and back covers for easy access to terminals. Transformers larger than 75KVA are suitable for floor or platform mounting only. Transformer terminations rated below 330A are supplied with suitable hardware and lugs for cable connection. Terminations above 330A are supplied with termination pads.
