Three-phase Oil-immersed Distribution Transformer with Conservator

The three-phase oil-immersed distribution transformer with conservator contains S9 series and S11 series, and the following paragraphs give brief introductions on them.

Features
1. The S9 series has a power range of 6.3-2500kVA, and it suits for 10KV, 50/60Hz power transmission and distribution systems.

2. The S11 series is often accepted for 6KV and 10KV power transmission and distribution systems. When compared with S9, the S11 series shows lowered no-load loss and reduced no-load current, thus realizing notable energy saving performance. Moreover, the noise level meets relevant requirements of environmental protection policy. So, this is an energy saving and environmental friendly product.

Applications
This S9 series oil-immersed distribution transformer is used to power lights or machines in residential areas, business streets, rural regions, industrial and mining factories, etc.

As for S11 series, it is commonly seen in factories, mining plants, agricultural industries, petrochemical engineering fields and more.
