 Insulation Engineering Research Center

In 2018, Rox has passed the acceptance of China Federation of mechanical industry, and the Engineering Research Center of Medium-High Voltage Solid Composite Insulation of Mechanic Industries by China Machinery Industry Federation was officially put into operation. The main work of research is to carry out reliability test and to optimize insulation materials and structures for medium and high voltage switchgear. The core subject comes from the problems and difficulties existing in insulation materials and insulation structures in the industry. The central goal is to deal with the difficulties by doing deep research on insulation materials and structures that affecting the reliability of switchgear.
