S11-35KV Oil Immersed Power Transformer
35kV Oil-Immersed Power Transformer 50KVA~35000KVA
online service
S11 Type 35 kV
Improved from S9 series product, S11 series product reduces the no-load loss by 30%, no-load electric current by 70~85%, average temperature by 10K, noise level by2~4db, and double the products service life. Even under 20% overloads, it can also work for long period of time.
