Three-Phase Medium Voltage Dry-Type Cast Resin Power Supply Transformer

Product Description

Three-Phase Medium Voltage Dry-Type Cast Resin Power Supply 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.
