The Tyree Group is celebrating our 70th Birthday

Founded in 1946 by Sir William (Bill) Tyree (decd 2013), the Tyree Group of companies and Tyree Transformers has a rich and fascinating history.

Sir William formed the original company at Camperdown Sydney with a £5000 loan and began business manufacturing electric motors.
The first order for transformers was placed in 1948 by the Sydney Water Board – two 50kVA, 11kV 415 units. These first orders ignited in Sir William a lifelong passion for transformers.
From this first order Tyree successfully tendered these products against the entrenched overseas owned competition, leading to a strong, long standing relationship that lasted many decades.
In 1952 a new factory was established in Kingsgrove Sydney, as Tyree had outgrown their original premises in Camperdown. Production was extended to include up to 1500kVA 33KV products and the first of these was delivered in 1953.

“I was able to build transformers two years ahead of any of my English-controlled competitors. It meant I was eventually able to buy them out”. (SWT, 2004)

By the early ‘60s Tyree were the largest manufacturer of transformers in the Southern Hemisphere.

After several attempts by Westinghouse, Sir William sold them the business in 1972, on the condition that he had free reign to run the company for 10 years.
Sir William left Westinghouse in 1978 and retained a small transformer business manufacturing pole transformers and a business manufacturing copper conductor and wire.

From initially humble beginnings in 1946, Tyree has always strived to provide a high level of service.

On his passing in 2013 Sir William bequeathed all of his business interests to a Trust whose primary purpose is to provide profits for distribution to the Tyree Foundation. The Tyree Foundation is a charitable organisation which continues his philanthropic efforts through donations to support engineering education, engineering and medical research projects.

The Tyree Group continues Sir William’s manufacturing legacy and charitable works

Tyree Group CEO Keian Barnard said ‘It is Sir William’s work ethic and can do attitude which is embedded in our company culture today. In a highly competitive global market for transformers and cable the Tyree Group continues to evolve ensuring we remain competitive and relevant to the changing needs of our customers’.

Our cable manufacturing business Tycab located at Dandenong, continues to expand and has been progressively re-tooled with state of the art machinery and automation solutions to improve our product quality, increase production capacity and to take advantage of labour efficiencies gained from automation. Expansion of our production facility is in progress with scheduled completion in June 2017 which will provide further growth opportunities for the next five years.

Today our transformer business located at Mittagong designs, manufactures, tests and services a comprehensive range of transformer products including small distribution transformers rated from 5kVA to 3MVA and power transformers to 45MVA in voltage classes up to 132kV.
In the past five years Tyree Transformers has continued to expand its product range to include kiosk substations, padmount substations, metering transformers and dry type transformers, in addition we have increased the size of power transformers we manufacture to increased MVA levels.

Reinvestment into our business is a continuing process at Tyree Transformers, with the recent implementation of automatic coil winding machines, automatic core winding machines and core annealing furnaces into our distribution transformer facility. In addition to this investment in machinery and automation, construction is underway to further expand the Tyree power transformer facility with a 40% increase in floor space scheduled for occupation in mid-2017.

‘As an Australian manufacturer we are proud to be continuing to grow and provide real opportunities for training and local employment. Our major clients in the power sector continue to undergo significant change due to privatisation and reduced budgets under the AER process. In response to these challenges, Tyree has continued to focus on reducing our cost base to remain competitive whilst continuing to improving our service levels to the Australian, New Zealand and Oceania region.’

Our success in delivering cost effective Australian made solutions, is reflected in our extensive repeat customer base made up of all of the major power utilities, rail transport operators, mining companies added to large number of industrial, defence, renewable energy generators and commercial clients across Australia, New Zealand, PNG and the Oceania nations.
