Fiberglass filament wound pipes are widely used in power systems for protecting and insulating high-voltage cables (110 kV and above). Their non-conductive nature eliminates eddy current losses inherent in metal pipes, preventing cable heating caused by electromagnetic induction. The manufacturing. InsulWynd® is our proven filament-wound, filament winding product utilizing fiberglass reinforcements in a specialized epoxy resin matrix. Forming of the tube is accomplished by winding a band of resin-saturated rovings around a rotating mandrel. This technology is known for its efficiency, cost-effectiveness, and versatility, making it. Our pipes are crafted from high-strength glass fiber, following a precise formula, and undergo processes such as winding, rolling, curing, and composite molding.
