ZTELEC produces pull strips made of polyester, epoxy, phenolic resins and related raw materials, and produces glass fiber composite products through various processes such as pultrusion, winding, pultruding, winding, molding, rolling, and pasting. It is made of alkali-free, glass-free glass-impregnated resin that is continuously drawn and formed by high-temperature curing.
Mainly used for electrical equipment insulation structure. Shapes are rectangular, I-shaped, angular, T-shaped, groove-shaped, circular tube-shaped, cylindrical, and other shapes.
The characteristics of our products: high mechanical strength, small partial discharge, dielectric loss, heat resistance, aging resistance, easy processing. The company is willing to serve the colleagues in the society with advanced technology, excellent quality, reasonable price and perfect service.
