30kVA 50kVA Dry Type Cast Resin Transformer for Indoor Installation
10KV 10~2500KVA Cast resin Dry Type distribution transformer
S11-M series hermetically sealed oil immersed power transformer has
the advantage of low loss, low noise, and high efficiency, which
can obtain a good energy-saving effect and reduce pollution.
Compared with ordinary oil-immersed transformer, hermetically
sealed transformers don't need an oil conservator, oil volume is
automatically regulated and compensated by an elastic corrugated
sheet of the corrugated tank. Transformer oil is kept out of the
air, which can effectively prevent deterioration and insulation
aging of oil, ad enhance operational reliability.
Advantage
1. Low loss, low noise, low partial discharge.
2. Strong anti-short circuit capability and high anti-lightning
impact level.
3. Excellent moisture resistance for operation at 100% relative
humidity.
4. Strong overload capability for long-term operation at 150%
loading.
Transformer normal service conditions
The height above the sea level is below 1000m;
Highest air temperature +40ºC;
Highest daily average air temperature+30ºC;
Highest annual average air temperature +20ºC;
Lowest outdoor air temperature -25ºC.
Characteristics
1. Thin resin structure that never cracks
2. Epoxy resin vacuum pressure casting process
3. Iron core model simulation analysis
