ZYD-I can remove water and gas in the insulating oil under high temperature and vacuity. it use more precise filter system to filter out impurities(filtering precision: 1-3um). 

ZYD-I is mainly used for purification of oil for transformer with voltage higher than 220kv. It can increase oil breakdown voltage by at least 40kv.They are suitable for oil treatment, vacuum oil injection, and cylic hot-oil drying in the installation and maintenance of big transformers.

Made with advanced techniques and innovative designs, the product is hailed as excellent in cost performance. Its oil treatment techniques and overall performance are at leading position in China..

Its features include high working vacuum, fast oil filtering, and sound oil quality protection. It is mainly used for purification of oil for high-voltage and extra high voltage electric facilities, and can increase oils breakdown voltage by at least 35KV at a time.

This series may include two types: regular closed type and trailer mobile type. They are suitable for oil treatment, vacuum oil injection, and cyclic hot-oil drying in the installation and maintenance of big transformers.

Besides, they can also be configured into three-stage high-vacuum oil purifiers to meet customers greater needs for oil treatment.
