Use
This kind of filter is mainly used for all kinds of low-viscosity oil (lower than No.40) and low-volatility oil in the large and mediate scale power systems. It is used to purify the isolating oil, turbine oil and machinery oil of large, mediate and small transformers, current-voltage mutual inductance device, capacitor, circuit breaker, and oil switch and so on. This kind of machine can work on-line to purify the worsened oil without stopping the electrified transformer, mutual inductance device, oil switch and so on. Thus, the oil can be improved back to its new quality level and resume its working function.
Characteristics
This Institute initially develops this new generation of efficient double-grade vacuum o
