Transformers

Quality New, Tested and Inspected Transformers

Power your systems with confidence using our premium selection of transformers, available in new, tested, and inspected condition for superior performance and reliability. 

Transformers deliver the correct voltage to your equipment, reducing the risk of overload, overheating, and premature failure. Power can be transmitted at high voltage (lower loss) and then stepped down where it’s needed—helping your system run more efficiently. From MCCs to pumps, drives, and control systems, transformers ensure your equipment receives stable, usable power. Proper voltage control helps prevent electrical issues that can lead to costly shutdowns or equipment damage.

Common transformer types

• Dry-Type Transformers – Ideal for indoor industrial and commercial applications
• Oil-Filled Transformers – Built for heavy-duty outdoor and utility use
• Isolation Transformers – Protect sensitive equipment and reduce electrical noise
• Step-Up / Step-Down Transformers – Match voltage to system requirements

Transformers are found in:

• Manufacturing plants and production facilities

• Commercial buildings and HVAC systems
• Utility and power distribution systems
• Renewable energy installations
