High Strength FRP Cable Trench, Fiberglass U-Type Cable Duct for Overground & Underground Power

Huangang high strength FRP fiberglass cable trench is U-shaped cable protection channel manufactured in Henan China via compression molding craft, made of glass fiber and resin composite raw materials. Smooth surface finish, customizable color and length (500/1000/2000mm optional). Available in light, medium and heavy load grades with multiple cover styles: slotted, perforated, wave, flat and heavy-duty lids. It supports underground, overground and side mounting installation

Product Overview

Huangang high-strength U-type FRP fiberglass cable trench is composite cable management duct specially developed for power engineering cable protection, produced in Henan, China with mature integral compression molding technology using glass fiber and thermosetting resin as raw materials. The integrated U-groove structure is matched with multiple supporting cover plates to realize fully enclosed cable isolation and protection. The product surface is smooth without burrs, standard factory lengths of 500mm, 1000mm and 2000mm, and arbitrary customized lengths with precision cutting service available. It is divided into three load-bearing grades: light, medium and heavy to adapt to pedestrian, vehicle and heavy machinery load scenarios. Multiple cover options include slotted, perforated, corrugated wave, flat and reinforced heavy-duty covers for different drainage and load requirements. Three installation modes: buried underground, surface overground and wall side mounting fit all site layout demands. Outstanding electrical insulation performance with zero conductivity and high dielectric strength eliminates electric leakage and short-circuit risks; stable thermal performance works normally between -40℃ and +120℃ without deformation or aging. Inherent composite anti-corrosion property resists acid, alkali, sewage and salt fog erosion, no regular painting or anti-rust maintenance required, ideal long-life cable routing solution for railway, subway, expressway, power plant and tunnel power transmission engineering.

Core Technical Parameters

Core Product Advantages

1. High Strength Compression Molded Integral Structure

   One-piece compression molding eliminates splicing weak points, three load grades meet pedestrian, truck and heavy equipment rolling load, no crack or collapse under long-term pressure.

2. Safe Non-Conductive Electrical Insulation Material

   FRP composite raw material is fully non-conductive with high dielectric strength, effectively isolate cable current, prevent electric leakage, short circuit and accidental electric shock hazards for power engineering.

3. Wide Extreme Temperature Adaptability

   Stable physical performance from -40℃ low temperature northern cold areas to 120℃ high-temperature tunnel and power station environments, no aging, softening or brittling.

4. Multi-Type Covers & Flexible Installation Modes

   Diversified cover designs balance drainage, ventilation and load resistance; three installation modes (underground, ground, side mount) adapt tunnel, roadside, factory workshop and railway track side construction layouts.

5. Permanent Anti-Corrosion & Maintenance-Free

   Resist acid, alkali, sewage, coastal salt fog and soil chemical corrosion, unlike metal cable troughs that rust and need regular anti-rust coating, zero post-installation maintenance cost.

6. Lightweight Easy Transportation & Installation

   Much lighter than concrete and metal cable trenches, reduce transportation freight and on-site manual lifting labor cost, fast assembly to shorten power engineering construction period.

7. Full Customization of Size & Color

   Standard lengths in stock for fast delivery, custom length cutting service and arbitrary color matching to coordinate with surrounding road, tunnel and power station landscape.

8. Multi-Scenario Universal Power Engineering Application

   Suitable for urban subway transit, intercity railway, highway road tunnels, thermal power stations, hydropower plants and industrial factory buried/overground cable routing protection projects.

Wide Application Scope

This insulated high-strength FRP fiberglass cable trench is dedicated cable protection duct for the following power and transportation infrastructure projects:
