Dry Type Amorphous Alloy Iron Core Distribution Transformer
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 good energy saving effect and reduce pollution.Compared with ordinary oil immersed transformer, hermetically sealed transformers don 't need oil coservator, oil volume is automatically regulated and compensated by elastic corrugated sheet of corrugated tank.Transformer oil is kept out of air, which can effectively prevet deterioration and insulation aging of oil, ad enhance operation reliability.
Transformer Chracteristics
Transformer Core
1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.
2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
3. Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.
