The epoxy resin fiberglass cloth laminated rod is made up of flexible rod fiberglass or similar material
The epoxy resin fiberglass cloth laminated rod is a round rod formed by impregnating alkaline glass cloth with epoxy resin by hot-pressing through the forming mold. It has high mechanical and dielectric properties. The epoxy resin fiberglass cloth laminated rod is suitable to be used as insulation parts in electrical machinery and electrical equipment, and can be used in humid environment and transformer oil.
Appearance of epoxy resin fiberglass cloth laminated rod
The surface should be smooth, free from bubbles, oil stains and impurities, and allow uneven color, scratch and slight height inequality without prejudice to use. Laminated glass rods with a diameter of more than 25mm are allowed to have cracks in the end face or section that do not interfere with use.
