Fiberglass electrical conduit, also known asGlass Fiber Reinforced Plastic (GFRP)TubingGlass FiberTo enhance material strength, bonded with unsaturated resins for molding, it can be categorized into low alkali, medium alkali, and high alkali pipes. Quality is determined by the alkali content. Fiberglass power conduits are strong in pressure resistance, lightweight, with smooth inner walls, and have a low friction coefficient, making them easy to install cables without damaging them. Fiberglass power conduits serve as cable protection devices, providing protection against external pressure or impact in underground facilities for power and communication cables.

It is widely used in power cable projects, transmission and transformation construction, communication and optical cable line projects, offshore and river-crossing cable protection projects, aviation airports, road and bridge traffic projects, industrial park cable projects, and underground cable projects for municipal construction; it can also be used in civil and industrial water supply, wastewater discharge, and other projects.
