National Manufacturing and Distribution: Keeping the Power On

Since 1981, NMD has been the partner electric utilities and industrial facilities turn to when they need critical electrical components, fast. Our job is straightforward: we make sure your power infrastructure keeps running by supplying the high-quality replacement parts you often  can’t find anywhere else.

Specialized Manufacturing: What We Do Best

We’re specialists, not generalists. NMD focuses exclusively on the components that literally conduct power through your heavy-duty equipment:

• Electrical Contacts – Precision-manufactured to meet or exceed original specs. 
• Contact Assemblies – Custom-built, ready to install, designed for perfect fit. 
• Copper Bus Bars – Engineered for your specific substation and industrial applications. 
• Gaskets – we create precision-cut replacements that maintain proper sealing and prevent contamination in transformers, circuit breakers, and switchgear.

  Our gaskets are engineered to withstand the extreme temperatures, pressures, and chemical exposures common in utility and industrial settings—keeping your equipment protected and operating reliably.

The NMD Difference: We Manufacture Hard-to-Source Parts

Your equipment is aging, but it’s built to last. The catch? The original manufacturer stopped making replacement parts years ago, or they have lead times that stretch for months.This where we come in.

We manufacture the critical components that are nearly impossible to source elsewhere. Whether a part is obsolete, discontinued, or just stuck in a seemingly endless production queue, we can produce it or in many cases, have it in stock. Through careful analysis of specifications, materials, and performance requirements, we create precise replacements that match (or improve on) the original. The result? You get the part you need in a fraction of the time, with quality assurance that guarantees it will work exactly as it should.

Our Specialty: Tap Changers & Circuit Breakers

We manufacture high-precision replacement parts for the equipment you service most often—tap changers and oil circuit breakers. These are the workhorses of your substation, and we help you keep them running safely.

We Support Equipment From:

• Westinghouse
• General Electric (GE)
• Allis-Chalmers
• Federal Electric
• And many more

Our goal is simple: help you maintain your existing equipment for its full lifespan, avoiding the expense and disruption of premature replacements.
