built for life

Our Company

Our story began more than nine decades ago when Jack Wilson arrived in Australia from the UK to work as a transformer electrical design engineer at a small factory in South Melbourne. A few years later, in July 1933, Jack started his own business under the name of Wilson Electrical Products with a simple vision: to establish a high performing business that invests in its people, technology, assets and processes. The “Chief”, as he was known to most of his early employees, had the ability to turn ideas into reality - a difficult task in those days, when technical experience, equipment and capital were limited. But Jack was ahead of his time - an exceptional engineer, businessman and leader who left an impressive legacy in Australian manufacturing.

Today, the Company, known as Wilson Transformer Company Pty Ltd (WTC), is Australia’s largest manufacturer of power and distribution transformer solutions operating two state-of-the-art manufacturing facilities in Melbourne and regional Victoria and service facilities across Australia and in the UK. WTC has also established and invested in joint ventures and subsidiaries in South East Asia, the Middle East and the United States.

We offer end-to-end transformer solutions, including product specification review, design, manufacture, factory acceptance test, installation, site testing, condition monitoring, maintenance and repair services, spare parts and asset disposal. 

Our remarkable enduring 90 years in the transformer industry has been achieved through our Built Smart for Life philosophy to deliver high-quality and reliable transformer solutions that meet our customers’ standard or complex requirements. This genuine commitment is supported by our team of experts we call ‘The Transformer People’.

WTC is a proud Australian based and owned business spanning three generations of the Wilson family. Looking into the future, we are committed to further building our engineering, manufacturing and service capabilities to support critical energy infrastructure and heavy electricity users across Australia and in targeted overseas markets.
