Fully sealed corrugated tank with vacuum oil-filling isolates oil from air, slowing insulation aging and extending service life.
Addresses insulation degradation caused by dust and humidity in harsh environments; eliminates routine oil sampling and testing, reducing maintenance workload.
Ideal for metallurgy, chemical, textile, and light industry sites with heavy dust and corrosive gases, maintaining high reliability under tough operating conditions.
Eliminates the oil conservator, reducing overall height by about 20% compared to conventional oil-immersed types, facilitating installation in space-constrained industrial plants.

Product Q&A
Q:What environments are S11-M series fully sealed oil-immersed transformers suitable for?
A:
They are suitable for petroleum, metallurgy, chemical, textile, light industry, and other sites with heavy dust, humidity, or corrosive gases, maintaining high reliability under tough operating conditions.
Q:Why do fully sealed transformers require no oil conservator or routine oil sampling?
A:
The corrugated tank and vacuum oil-filling process allow the elastic corrugated fins to compensate for oil volume changes due to temperature fluctuations. The oil is completely isolated from air, preventing insulation degradation and oil aging, thus eliminating the need for routine oil sampling and testing.
Q:How significant are the loss differences among S11-M, S13-M, S20-M, and S22-M?
A:
Energy efficiency increases progressively. For example, S22-M offers approximately 50% lower no-load losses compared to S11-M (based on a typical 1000kVA rating), saving tens of thousands of yuan annually in electricity costs.
