7) If the application environment is different from the above standard conditions, please contact for customized designs.
4. Product advantages
1) Safe flame retardant, fireproof, explosion-proof, pollution-free, can be directly installed in the load center.
2) Low loss, maintenance-free, low comprehensive operating cost, obvious energy-saving effect.
3) Good moisture-proof performance, can operate normally at 100% humidity, and can be put into operation without pre-drying after decommissioning.
4) Partial discharge capacity< 5Pc, low noise, strong heat dissipation ability.
5) Strong load capacity, low product temperature rise, strong heat dissipation capacity, 140% load when forced air cooling to meet temporary emergency needs
6) Foil coils are insulated with DMD prepreg cloth to improve short-circuit resistance and service life.
