Fiberglass electrical conduit, also known asGlass Fiber Reinforced PlasticTubing, inGlass fiberTo enhance material properties, it is bonded into shape with unsaturated resins, and can be categorized into low, medium, and high alkali pipes. Quality is determined by the alkali content. Glass fiber reinforced plastic (GRP) power conduits are characterized by strong pressure resistance, light weight, smooth inner walls, and low friction coefficients, making them easy to install cables without damaging them. GRP power conduits serve as cable protection devices in underground facilities for power and communication cables, providing protection against external pressure or impacts.

It is widely used in power cable projects, transmission and transformation construction, communication and optical cable line projects, cable protection projects across seas and rivers, aviation airports, road and bridge traffic, industrial park cable projects, and underground cable projects for municipal construction; it can also be applied to civil and industrial water supply and wastewater discharge projects.
