Wilson Transformer Company’s Distribution Transformer Business Unit produces standard and specialised transformers ranging in size from 16kVA polemount transformers up to 5,000kVA ground mount transformers at our Wodonga facility. These products form a critical part of electrical distribution networks and ensure reliable supply of electricity to homes and industry.
Our distribution transformers are designed and manufactured for standard and specific customer requirements. Standard proven design methodologies, supported by extensive short circuit tests have proven the product design and ensure superior product performance in the field. Our products are manufactured down a controlled production line with standard work practices utilising state of the art equipment and processes that are subject to strict quality control practices. The product design incorporates step lapped stacked or wound cores with rectangular windings and a suitable clamping structure, resulting in very strong, short-circuit proof distribution transformers. The core and coil assembly is integrated into a tank with or without fin-cooling or alternatively separate radiators to provide appropriate interface connections to the customer’s system.
All transformers are subjected to comprehensive routine tests and specified type tests, in accordance with the customer’s requirements, relevant standards and Company procedures. All high voltage tests are performed in purpose built test facilities that are isolated from the main assembly stations.
Pole mount transformers are designed and manufactured to standard or special requirements, primarily for distribution network companies. Our range includes transformers from 16kVA up to 500kVA, with primary operating voltages of 11kV, 22kV and 33kV. The standard range complies with the AEEMA/ESAA specification for ‘Polemounting Distribution Transformers’.
Ground-mounted distribution transformers are designed and manufactured for standard or special requirements. Our range includes transformers from 500kVA up to 5,000kVA with multiple configuration options that can be customized to our customer’s needs.
