3 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. Designed for indoor installation in hotels, schools, factories, industrial and commercial buildings where a reliable power source is required for lighting and other low voltage equipment and machinery. Features Using Computer Aided Designs (CAD) our engineers have created a range of highly efficient transformers having long trouble-free life with reduced weight, size and cost. Ventilated openings in the enclosure are coordinated with the cooling ducts in the coils to ensure proper natural circulation of air for long life and minimum losses. 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 112.5 KVA and larger are supplied with brackets 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.
