| I. Define and purpose |
| This laminated product is formed through heat pressing after electric industry alkali glass cloth dips into the epoxy resin. It has high mechanic and dielectric performance, applicable as insulation structural components for electromechanical/electrical equipment, as well as used under damp environmental conditions and in oil of transformer. And it can Withstand a variety of chemical solvents and acid erosion. |
