Products Description
FRP cable conduit is manufactured using filament winding or pultrusion processes. They are composed of glass fiber yarns and fabrics combined with epoxy or polyester resins, along with additives for insulation, flame retardancy, and aging resistance. Formed through high-temperature curing, the conduits feature smooth inner walls and a bell-and-spigot connection design; each unit undergoes hydrostatic pressure and insulation performance testing prior to shipment.

Product Advantages
FRP cable conduits offer advantages such as corrosion resistance, aging resistance, excellent insulation properties, and ease of installation; they are widely selected for municipal power, chemical industry, coastal, and underground cable projects. Key advantages include:
Corrosion and Aging Resistance
Suitable for long-term use in coastal, marine, and corrosive chemical environments; they do not rust, flake, or degrade, offering a service life of up to 50 years.
01
Insulation, Non-conductivity, and Non-magnetism
Manufactured from non-metallic insulating materials, they are non-conductive and non-magnetic. They generate no eddy current losses or electromagnetic interference during operation, require no grounding during installation, and eliminate safety hazards associated with electrical leakage.
02
High Compressive Strength
Capable of withstanding long-term pressure from underground burial (such as beneath roadways) and external mechanical impacts without cracking or deforming; maintains structural stability and adapts to complex geological and construction environments.
03
Smooth Inner Wall, Low Resistance, and Excellent Sealing
The smooth inner wall is free of burrs or scaling, preventing abrasion to cable sheaths. Additionally, the product offers superior sealing performance, effectively blocking groundwater, silt, and debris to prevent pipeline blockages and moisture-related cable damage.
04
Customization supported
Our FRP cable conduit offer comprehensive customization options regarding product length, inner diameter, wall thickness, and ring stiffness.
