Product Description
S11 distribution transformer oil immersed transformer 10/0.4kv power transformer

S11/S9 11kv oil immersed transformers are widely used for power supply & distribution in

industrial and civil occasionsto step down grid voltage (11, 10.5, 10, 6.3, 6KV) to line 

voltage 400, which can serve both indoors and outdoors at an ambient 

temperature range -25℃ to 40. With reasonable structure designthe transformers 

are qualified to withstand short-circuit and overload, and are free of maintenance and easy to repair. 

The transformers have S9 and advanced S11 series, the S11 is more recommended for less loss of both load and no-load.
