3 Phase Double Winding 110kv 220KV high voltage oil type power transformer /insulation power transformer Copper Material
Main Features
110kV three-phase oil immersed power transformer is manufactured according to iec60076 standard and standards gb1094.1 ~ 2-1996 and gb1094.3.5-1985 of the Electrotechnical Commission, with frequency of 50Hz, which can be used for power transmission and transformation of industrial and agricultural power grid. The new series of 110kV power transformers are characterized by low noise, low partial discharge, low temperature rise, short circuit resistance, impact resistance, no leakage and beautiful appearance.
1) With reliable low partial discharge level, low loss, low noise, high reliability and strong anti-abrupt short circuit capacity.
2) The fully sealed products without windlass cover sell well all over the nation.
3) Partial discharge level: the apparent discharge magnitude under the voltage of 1.5 times the nominal voltage is less than 80pC;
4) Loss: non-load loss ratio is about 30% lower than IEC standard;
Reliability: none of the in-service products has experienced damage accidents or oil leakage;
