Marathon Transformer has over decades of continuous service and a legacy of excellence in the transformer industry. With nearly a century of combined expertise in transformer repair, manufacturing, remanufacturing, and sales, the company has built a reputation for quality and reliability.

Today, Marathon manufactures a broad range of products, including pad-mounted, pole-mounted, substation-style, power transformers, and auxiliary transformers. These are produced using a combination of local production capacity and the innovative Sliding Depth Supply Chain (SDSC) model—a flexible and scalable approach that enables the company to deliver thousands of units annually.

A New Era of Growth and Innovation

The company recently entered a transformative new phase, embracing the SDSC model to improve production efficiency and supply chain resilience. This strategic evolution was supported by collaboration with industry experts and global supply chain specialists, enabling Marathon to meet surging demand in emerging markets such as Bitcoin mining and artificial intelligence (AI) applications.

Commitment to Rapid Service and Federal Partnerships

In addition to transformer manufacturing, Marathon is committed to rapid, on-site service—often within 24 hours across most U.S. states. The company serves a wide array of clients, from power utilities and electric grid operators to federal agencies, including those responsible for airport and air traffic management infrastructure.

Unprecedented Growth and Market Reach

Marathon Transformer now produces over 500 MVA in distribution transformer capacity annually, excluding contributions from power transformers and service operations. This production milestone highlights the company’s scalable infrastructure, innovative capabilities, and strong market position across a range of transformer designs and applications.
