VanTran’s Medium Voltage (MV) Cast Resin Transformers are built to deliver reliability and performance in the most demanding environments. Whether it’s grids exposed to harmonic distortion, switching surges, extreme climates, or high-altitude installations, these transformers are engineered to withstand it all.
With ratings from 75KVA to 7,500KVA, our Cast Resin Transformers are designed to ensure continuous operation, even in harsh conditions such as desert heat, high humidity, salt exposure, and temperatures as low as -50°C. Capable of handling short-term overloads up to 450% and long-term loads up to 140% when equipped with fans, they are the perfect choice for power systems that require high availability.
In addition to their robust performance, these transformers are built for mechanical stability in challenging settings such as seismic zones, overhead cranes, ships, and other unstable installations.
Trust VanTran to deliver reliable, high-performing transformers tailored to meet your specific needs.
