Performance Characteristic
Transformers can have an 80-degree, 115-degree or 150-degree C-rise. The most efficient transformers generally have the lowest C-rises and operate the coolest. Units with low C-rises are essential for applications where optimal performance and efficiency are crucial, including hospitals, schools, alternative energy and manufacturing facilities.
The main insulation of the C-class insulation three-phase non-encapsulated dry-type transformer is made of C-class (heat-resistant temperature 220℃) Nomex paper, which is cured by VPI vacuum pressure impregnation and high temperature. It has extremely high flame retardancy, heat dissipation performance and overload capacity. It is safe, reliable, environmentally friendly and energy-saving. It is suitable for environments with high fire protection requirements, small sites, and large load fluctuations.

Drawing
WINLEY‘s C class insulation transformer advantage
- Enhanced Safety: Dry type transformers featuring Nomex insulation eliminate the risk of flammable materials, such as fluids and combustible components, providing a safer operating environment.
- Reduced Transmission Losses: With superior insulation, these transformers can be placed closer to their loads, minimizing low-voltage line lengths and consequently lowering transmission losses.
- Cost-Effectiveness: Designed to withstand temperature rises up to 150 degrees Celsius, transformers with premium-grade insulation require less conductor and steel. This reduction in material requirements leads to lower overall costs and simplifies installation.
- Improved Harmonic Loading: Dry type transformers with Nomex insulation have enhanced capabilities for managing high temperatures caused by heavy harmonic loads, making them suitable for demanding applications.
