I. Overview
Glass fiber reinforced plastic (GRP) cable protection pipes are a type of piping made by molding a resin matrix reinforced with continuous glass fibers and their fabrics, either through computer-controlled winding or pultrusion processes.
II. Key Features
High strength, suitable for direct burial under traffic lanes without the need for concrete protection layer, capable of accelerating construction progress. ◎Excellent flexibility, resistant to damage caused by external heavy pressure and foundation settlement.
Excellent electrical insulation, flame-retardant, and heat-resistant properties, ensuring long-term use at high temperatures up to 130 degrees Celsius without deformation.
Corrosion-resistant and long-lasting, it can withstand erosion from various corrosive mediums such as acids, alkalis, salts, and organic solvents, with a lifespan of up to 50 years.
The interior wall is smooth, preventing any damage to cables. The rubber sealing ring features a plug-in joint for easy installation and connection, and accommodates thermal expansion and contraction. With its low density and lightweight, it can be lifted by a single person and installed by two, significantly reducing the construction timeline and installation costs. It also avoids the issues of prolonged road excavation and disruption of urban traffic order.
Non-electrolytic, non-magnetic. Unlike magnetic materials such as steel pipes, it does not generate eddy currents that promote cable heating and damage.
Wide Application Range: The glass fiber reinforced plastic cable protection conduit is used for cable burial and laying as a protective tube, and is also suitable for high-demand scenarios such as cable crossings over bridges and rivers. With a matching professional pipe cushion assembly, it can form a multi-layer, multi-column conduit arrangement.
III. Connection Methods
Glass fiber reinforced plastic cable pipes mainly use "O" type sealing rings for socket and spigot connections, while special positions can also utilize flange or bonding methods for connections.
Section 4: Application Fields
The Glass-steel Cable Protection Pipe is suitable for the protection conduits of power and communication cables in various environments. Particularly, it is highly effective in special situations such as cables passing through major traffic crossings and over rivers, bridges, etc. It showcases its superior performance with ease of installation and high strength, and is widely used in infrastructure construction fields such as power, communication, transportation, and civil aviation airports.
