We grasp the direction of industrial development and take the world as our stage, requiring our Cleveland Open Flash Point Tester, Transformer Winding Resistance Tester, Kinematic Viscosity Tester and services to be based on international cutting-edge standards. Quality is the foundation of the survival of an enterprise. Improving production efficiency, developing high-tech products, learning Western manufacturing technology, and creating our own brand are our consistent pursuit! We emphasize the effective combination of self-management and synergy sharing of various businesses, internal training and external introduction of talent echelon, and independent and integrated innovation in technology R&D.
1. Introduction
Series ZYD-D Double Stage Vacuum & Double Stage Chambers Type Transformer Oil Purification Machine is developed based on Series ZYD, which mainly satisfy some clients who want the highest special transformer oil's quality even higher than new oil's quality.
It is mainly for treating & regenerating the used and new transformer oil, mutual oil, and switch oil, which power transformers are above 110 kV in the big power station and power transmission station.
The oil's quality after purified by Series ZYD-D is equal or higher than new oil's quality, which can be used directly into transformers.
This oil degassing system is equipped with two stages of vacuum degassing and dehydration chambers which is capable of removing large portion of water content and gas/air content from the oil. It's two times than normal one stage vacuum chamber.

Note: 1. The dimension and weight will be changed with changing of technical specs.
2. All the specs can be customized according to client's requirements.
4. Advanges of ZYD-D machine
1) With two stage vacuum chambers, shorten evaporation time, increase dehydration and degassing time.
2) The ultimate vacuum degree can reach 10Pa.
3) The filling materials in the vacuum separate tank, which expand 720times of the evaporation area. It can get higher water clean in shorter time and evaporate the water enough.
4) Oil breakdown voltage is larger than 75KV, and it can reach 80KV.
