C Class Insulation 500k Three phase Dry type transformer Step up 208Y/120V to 600Y/347V
Summarization
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.

Performance Characteristic
1. C-class insulation (one level higher than H-class insulation), excellent heat dissipation conditions, great overload capacity, 130% overload without the need to put in a fan can be long-term safe and stable operation; under IP45 conditions, no forced air cooling is required and it can still operate safely and stably for a long time.
2. Extremely high safety and flame retardant performance, long-term combustion at 800℃ high temperature without smoke generation.
3. Strong ability to withstand thermal shock (can be fully loaded immediately at -50℃).
4. 100% waterproof sealing.
5. No partial discharge.
6. Dirt and water repellent, can withstand acid and alkali corrosion and fungal or mold invasion.
7. Environmental protection concept - low noise, no harmful gas, no pollution to the environment, easy to decompose and collect after life, protect the environment, in line with the trend.
