We have a long history of experience dating back more than 92 years

The year 2021 marks the Silver Jubilee of Pennsylvania Transformer Technology, Inc.(“PTTI”). This is also a very special year where the world is emerging from an unprecedented global health crisis creating unforeseen constraints in every sphere of life. It’s therefore important for us to reflect on the past, and more importantly, to focus on the future.

PTTI was officially founded 25 years ago, but our wealth of expertise can be traced back to more than 92 years back. Reflecting on the rich history of this company, 

we began as Pennsylvania Transformer in the North Shore in 1929 and was subsequently integrated into Mc Graw Electric and Mc Graw Edison between 1952~57 to become a major innovator and power equipment manufacturer in the USA. The company was acquired by Cooper Power Systems in 1985. Ravi Rahangdale and the Rahangdale family purchased the assets and intellectual property from Cooper to create PTTI in 1996 and continues to hold a majority interest in the company.

Over the past 25 years, the company innovated and extended its product line adding complex product lines like Mobile Transformers, Circuit Breakers, Voltage Regulators, Large Power Transformers and unitized sub-stations to its portfolio. We have been expanding into new customer segments like Renewables and spending significant efforts to broaden our customer base with a long-term focus.

All these changes over the last 25 years came with great efforts, resulting in PTTI being recognized in the market as a professional company, which drives its business through knowledge, expertise, hard work, and focus on customer service driven by a sustainable approach. We are recognized as a niche and a premium domestic player in the Transformer market in the country.

To all our employees, customers, stakeholders and friends – I thank you for your contribution and continued commitment to PTTI.

We are all prepared to make this company stronger by finding solutions to the challenges of our industries, investing in the business, targeting growth markets, focusing on sustainability, and making sure that we overcome the short-term challenges imposed by the global health crisis in good shape.

Happy 25 years of PTTI!
