About Grant Transformers

A rich and long history of Australian ingenuity and engineering is what is offered by Grant Transformers.

Ron Grant founded Grant Electrical Industries Pty Ltd in 1931 originally, due to the depression of the era, the primary business at the time was that of an electrical contractor, how it evolved over the years was quite impressive. One of Ron’s sayings, one which is adopted still today and which resonates with the current team at Grant Transformers “We’re constantly looking for products that the fellow down the road hasn’t got the ability to make… or think out or develop”

The initial work involved all types of electrical work including transformers.

With rapid growth during the 50’s and 60’s the company comprised the following divisions: –

  • Grant Electrical Switchboards
  • Grant Electrical Contractors
  • Grant Elevators (Elevator Sales)
  • Grant Transformers
  • Grant Bosch tools

The company employed over 80 employees in the 1980’s.

In 1992 the business was broken into:

  • Grant Transformers
  • Elevator Sales

Grant Transformers continued to grow and provide a range of all types of dry and epoxy transformers for industrial needs as well as specially designed DC systems.

Over the years Grant Transformers developed a high level of technical and manufacturing expertise.

A key part of this expertise was to understand how customers were intending to use the transformer and translate this to technical requirements to enable a reliable product to be manufactured.

In this way Grant Transformers developed skills in being able to provide the customer the exact solution they required.
