Load tap changers (LTCs) are critical components in power transformers that regulate output voltage by adjusting winding connections under load without interrupting service. Widely used in utility, substation, and industrial power systems, LTCs help maintain voltage stability, improve power quality, and ensure consistent performance in high-voltage applications. Parts Super Center supplies OEM and replacement load tap changer parts designed for legacy and modern transformer systems from leading manufacturers such as GE, ABB, Westinghouse, and Eaton. Our inventory supports maintenance, repair, and retrofit applications, helping extend equipment life and reduce costly downtime.
Available load tap changer solutions include:
- LTC contact kits (moving and stationary contacts)
- Arc contacts and interrupter components
- Drive mechanisms, motors, and gear assemblies
- Selector switches and tap changer assemblies
- Control components and replacement parts
Load tap changers are subject to mechanical wear and electrical stress, making regular maintenance and part replacement essential for reliable operation. Properly maintained LTC systems help prevent voltage fluctuations, reduce arcing damage, and extend transformer service life. Common applications include voltage regulation in power transformers, substation equipment, utility transmission systems, and industrial power distribution networks. Parts Super Center supports sourcing by OEM part number, specifications, and technical drawings, ensuring accurate fit and performance. Whether you are replacing worn contact kits or sourcing hard-to-find LTC components, our team provides technical expertise and cross-referencing support for legacy transformer systems.
