A comprehensive analysis of high-performance cable support systems
FRP cable tray is a cable support system made of glass fiber reinforced plastic, which has excellent corrosion resistance, insulation and mechanical strength. As an important facility for modern cable laying, FRP cable tray is widely used in power, communication, chemical, petroleum, sewage treatment and other industries. Compared with traditional metal cable trays, FRP cable trays have significant advantages such as light weight, easy installation and long service life, and are particularly suitable for special environments with high humidity and strong corrosion.
FRP Ladder Type Cable Tray
Feature
The FRP ladder cable tray is composed of side beams and crossbars on both sides, shaped like a ladder, and has the following structural features:
- Open design: easy to dissipate heat and maintain, suitable for laying large-diameter cables
- Adjustable crossbar spacing: standard spacing is 150mm, which can be adjusted according to the cable diameter
- Side beam reinforcement: adopt “I” or “C” cross-section design to improve overall rigidity
- Surface treatment: ordinary or anti-slip crossbars are optional to prevent cable sliding
- Performance advantage analysis
Excellent ventilation and heat dissipation performance: the open structure increases the cable heat dissipation area by more than 50%, which can reduce the cable working temperature by 10-15℃ - Outstanding bearing capacity: through the optimization of structural design, the span of the ladder bridge can reach 4m (heavy duty)
- Easy installation: bolt connection, no special tools are required, and the construction efficiency is increased by 30%
- Easy maintenance: the open structure is convenient for cable addition and reduction and troubleshooting
- Good economy: saves 20-30% of materials compared with the same specification trough bridge

FRP Trough Type Cable Tray
The FRP trough cable tray adopts a fully enclosed structure, consisting of three parts: trough bottom, trough side and cover plate, forming a complete protection space. This structural design gives the trough cable tray the following significant features:
Feature
Fully enclosed protection: effectively prevents dust, moisture and corrosive gases from intruding, and protects cables from external environmental influences
High-strength design: adopts thickened wall panels and reinforcing ribs, and the load-bearing capacity can reach Class C (heavy) standards
Modular combination: the standard length is generally 2 meters/section, which can be flexibly combined through accessories such as straight-through, elbows, and tees
Smooth surface: the inner wall is smooth and burr-free to avoid damage to the cable insulation layer during laying

| XCQ-400 | 400 | 100 | 5.0 | 11.0 | 1800 |
Installation points and precautions
- Bracket spacing: Bracket spacing is generally 1.5-2m when installed horizontally, and no more than 1.5m when installed vertically
- Grounding requirements: Although FRP itself is insulated, a dedicated grounding wire is still required for safety reasons
- Expansion joint treatment: When the straight section exceeds 30m, a telescopic compensation device should be installed
- Turning radius: The minimum turning radius should not be less than the minimum allowable turning radius for laying cables in the bridge
- Blocking measures: Fire blocking should be done when crossing different fire zones
