Dry Transformer Opening Dry Type 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.
Products Features
1. Flame retardant, epoxy resin as a dry-type transformer insulation material itself is difficult to burn, and will not support combustion in the event of a fire.
2. Moisture-proof and dust-resistant, the surface of the dry-type transformer winding is sprayed with three anti-paints, and the transformer can operate normally under the harsh environment such as dust and humidity.
3. The structure is firm, and the dry-type transformer windings are formed by epoxy resin casting and curing, which has high mechanical strength and strong short-circuit resistance.
4. Strong overload capacity, dry-type transformer insulation grade is F-class, high heat-resistance grade, super-brand rating operation capacity is improved.
5. Easy to maintain, dry-type transformers do not need to use transformer oil, after long-term shutdown, after cleaning and testing, you can run the power.
