Established in 1966, CTR began its journey with the manufacturing of Capacitors, Tapchangers, and Radiators(.) Through continuous innovation and sustained investment in research and development, the company has evolved its capabilities to design and manufacture advanced On-Load Tap Changers (OLTC) and De-Energized Tap Changers (OCTC), delivering reliable and efficient solutions aligned with changing market and customer requirements.
As Indian Railways is rapidly modernizing under the Government of India’s Mission Raftaar initiative, focused on increasing train speeds, improving operational efficiency, and maximizing the utilization of existing railway infrastructure.A key contributor to this transformation is the adoption of Intank On-Load Tap Changers (OLTCs) and De-Energized Tap Changers (OCTCs) in RDSO-approved traction transformers. These advanced tap changer solutions play a vital role in ensuring reliable and efficient power supply for modern railway operations.
As railway networks continue to expand and operate at higher speeds, Intank tap changer technology is becoming an essential component of traction transformer design. By delivering dependable voltage control, improved safety, and lower lifecycle costs, these solutions are helping Indian Railways achieve the objectives of Mission Raftaar and build a faster, more efficient transportation future.
CTR developed and Type Test completed for De-energized tapchanger (OCTC) as per RDSO specification and OCTC model are standardized for 245 kV and 170 kV and approved by RDSO for supply to traction transformers.
