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.
