The product performance parameters meet IEC Standard requirements, products are leading in the country.
The epoxy glass fiber winding tube is made of uninterrupted fiber wet winding. We use the top domestic CNC winding equipment to adjust the winding angle from 28° to 89°. (The winding angle and tension system can be adjusted according to your requirements to meet your mechanical performance requirements)
Temperature resistance: 150 degrees, 180 degrees, 220 degrees or more
Main materials: epoxy resin + alkali-free glass fiber
Color: Natural color is light green, other colors can be customized
