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 distribution and power transformer solutions operating two state-of-the-art manufacturing facilities in regional Victoria and metropolitan Melbourne with 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.

Our Journey from 1933 


Wilson Transformer Company (WTC) was founded by Jack Wilson in Sturt Street, South Melbourne under the initial Company name of Wilson Electric Products. During the first four years, the Company moved to Dorcas Street and then Wells Street, South Melbourne. During this time, the Company also changed its name to Wilson Electric Transformer Company. Much later, in 1987, the Company name was changed to Wilson Transformer Company.


WTC moved its operation to a 17,000 square feet site in Crockford Street, Port Melbourne, the site of the old Port Melbourne market.


WTC moved its operations to Glen Waverley, Australia, the present site of its Head Office and Power Transformer manufacturing operations. The Glen Waverley site was continuously upgraded with major expansions in 1959, 1963, 1969 and then in 2009.


A Technical Design and Manufacturing Information Agreement was entered into with Ferranti Ltd of the UK for transformers 132kV and above. At the same time, Ferranti acquired a 23% equity in the Company.


The first two 10MVA 132kV transformers were produced for the Woomera rocket range.


A small distribution transformer factory was established in South Australia to serve the local market.


Robert Wilson joined WTC after completing his engineering degree at Monash University.


Jack Wilson, the Company founder, died on 30 March 1972 following a short illness. 1973 Order received for two 30MVA 220kV transformers for the SECV Newport Power Station. These were to be the second 220kV units produced by the Company, the first being for Tasmania.


Robert Wilson appointed Managing Director. Later the same year Jim Murray rejoined the Company.


WTC moved part of its existing distribution transformer manufacturing to a new plant in the Albury/Wodonga. This site enabled the Company to utilise modern manufacturing techniques and production flow to produce its newly developed range of distribution transformers.


The 23% Ferranti equity in WTC which had been transferred to NEI was acquired by the Wilson Family and senior employees.


The first of many 150MVA 220 kV transformers was produced for the SECV for the Victorian transmission grid.

A Joint Venture EPE Wilson Transformers Sdn Bhd (EWT) was established in Malaysia where distribution transformers in the range of 50kVA to 2500kVA and up to 33kV are manufactured along the same principles as those in Wodonga. The JV plant is a major supplier in the Malaysian market.


From 1993 to 1998 around 150 power transformers ranging in size from 12.5MVA 33kV to 240MVA 275kV supplied to Malaysia.


A strategic decision was made to create separate Power and Distribution Transformer Business Units to generate focus within the businesses. Following this decision, the remaining distribution transformer manufacture was transferred from Glen Waverley to Wodonga.


WTC opened a United Kingdom sales and support office to service the customers in the UK, the Middle East and Africa.
