1. General
Model ZLS Multi stage vacuum transformer oil purification machine is being capable to re-improve the power transformer oil characteristics up to the recommended value by the transformer manufacturer or IEC-156 standard which one is higher.
The Oil Treatment Plant can be PLC fully automatic or manual operation.
The Chongqing transformer oil purification plants can be also used for high voltage power transformers 400/230 KV with different power capacity varied up to 300 MVA, 230/ 66KV with different power capacity varied up to 125 MVA and 66/20 KV with different power capacity varied up to 40MVA.
