Sino-NSH-VFD is a dehydration and degassing unit
with thermal and double-stage vacuum processing. Sino-NSH-VFD is mainly used to improve the
properties of insulating oils in electric power transformers and
other oil filled electrical equipment. It can remove dissolved and
free water, dissolved gas and particulate impurities effectively so
as to increase special indexes of insulation oil. 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
*5kV to over *0kV. 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
