MARS Transformers: high-voltage solutions, humble beginnings

MARS Transformers started as a rough idea on the back of a worn diner receipt.

While Bill Mars and HLI Rail & Riggings’ Managing Partner, Ross McLaren, were out to lunch, the two decided to combine their years of experience into one high-voltage solution. From there, MARS Transformers - an efficient, single-source solution for the supply, delivery, assembly, and testing of large Power Transformers, was born.
