Cast Resin Distribution Transformers of Philippines offer a robust and environmentally friendly solution for electrical power distribution. These transformers are constructed using epoxy resin, which encapsulates the winding and core, providing excellent protection against moisture, dust, and chemical agents.

Cast resin Transformers Features & Benefits
  • Expected service life of over 20 years
  • Increased efficiencies compared to traditional CRGO transformers
  • Vibration proof cast resin transformers
  • Reliable even in extreme conditions
  • Low-maintenance solution due to absence of oil, and, crack and moisture-resistant nature of resin

Typical primary voltages: 3.3kV, 6.6kV, 11kV, 11-6.6kV DUAL, 33kV

Typical secondary voltages: 280V, 315V, 400V, 415V, 433V, 480V, 690V

Cast resin transformers need the air to be cool as they are dry type transformers. Therefore, it eliminates extra costs and labour for liquid-level checking, oil testing, oil recycling costs, and dielectric testing for moisture absorption. They are an easy maintenance option as they only require a vacuum & bolt torques during a routine annual inspection by a trained engineer.

Due to the robust nature of cast resin transformers, and with the absence of oil, it makes them incredibly low-risk and versatile in their range of applications. They can safely operate in even the most demanding or hazardous areas. Operation is even possible when abrupt environmental changes occur in ambient temperatures between -25ºC and 50ºC (depending on the load cycle).
