Applications
Our Pole Mount Transformers
MPS offers single-phase pole-mounted distribution transformers engineered for residential overhead distribution loads. They are also appropriate for industrial lighting, light commercial loads, and various power applications. These transformers are designed to meet the application requirements typically found on electric utility distribution systems.
Each unit is manufactured in compliance with IEEE, ANSI, and NEMA standards. The transformers are available with three different fluids: mineral oil, silicone transformer oil, or less flammable seed oil. In general, pole-mounted transformers are equipped with off-load tap changers.
