Sino-NSH-VFD combines vacuum flashing evaporation technology and delaminating gradual-close filter technology to reach best performance of oil purification. Meanwhile, by integrating efficient thermal and double-stage vacuum, the breakdown voltage is highly improved, which can be increased from 25kV to over 70kV.
Sino-NSH-VFD maintains an optimized structure and safe controls so as to meet comprehensive requirement of transformer manufacturers and service companies.
Four main security and protecting systems:
1，Liquid level auto-controlling system
2，Auto pressure protection system
3，Steady temperature auto-controlling system
4，Electrical auto-protection system to control electric phases,voltage and overload of pump
