Product Description

Glass fiber reinforced extruded profiles for electrical insulation
-- Bracing rods for dry type transformers


 Product Specification
The product is made of continuous glass fiber bundle, belt or cloth impregnated with resin glue solution, under the action of the pull, through the extrusion mold forming, curing, continuous production of unlimited length profiles, such as bars, pipes, solid profiles (I-shaped, groove, square profiles) and so on.

Features and Usage
The product has high mechanical strength, excellent dielectric properties, low water absorption, arc resistance, flame retardant. The heat resistance grade is F, H;
The product is suitable for insulation support of F and H class dry transformer windings heat dissipation airway


Technical requirements
1. Appearance
The surface is smooth and free from bubbles, wrinkles, cracks and yarn skipping. Other defects, such as abrasions, indentations and stains, are properly avoided. A small amount of color spots are allowed.
