Fire pipe trough type cable tray

Fire pipe trough type cable trays are fully enclosed, fire-resistant cable management systems designed to protect cables from fire, mechanical damage, dust, moisture, and electromagnetic interference.

Overview

A trough type cable tray is a rigid, continuous structure with a solid or ventilated bottom and side rails, providing superior support and protection for electrical and data cables compared to ladder-type trays . The fire-resistant variant enhances safety by offering flame retardant properties, making it suitable for high-risk environments such as high-rise buildings, tunnels, subways, and industrial plants .

Key Features

• Fully Enclosed Design: Protects cables from dust, moisture, and external mechanical or electromagnetic interference .
• Fire Resistance: Maintains cable operation during fire events, reducing the risk of system failure .
• Anti-Corrosion Performance: Suitable for corrosive environments like chemical plants and electroplating facilities .
• Structural Stability: Can span long distances, supporting large industrial or commercial installations .
• Directional Shielding: Prevents interference for sensitive cables such as communication, computer, and thermocouple lines .

Applications

Fire pipe trough type cable trays are widely used in scenarios requiring high fire performance, environmental protection, and long-span cable routing:

• Industrial plants and commercial buildings
• High-rise buildings, tunnels, and subways
• Electronic factories and dust-free workshops
• Corrosive environments like chemical and electroplating plants

Installation Considerations

• Material Selection: Steel trays offer higher load capacity, while aluminum provides corrosion resistance and lighter weight .
• Firestopping Compliance: When passing through walls or slabs, openings must be sealed with fire-rated boards, mineral wool, or firestop packs to maintain fire integrity .
• Support and Load: Ensure proper support spacing and load capacity to prevent structural failure and cable damage .
• Modular Design: Allows easy customization and expansion of cable runs .

Benefits

• Protects cables from fire, dust, moisture, and mechanical damage
• Reduces electromagnetic interference for sensitive systems
• Enhances safety and reliability in critical installations
• Supports long-span and high-volume cable routing efficiently In summary, fire pipe trough type cable trays combine structural strength, fire resistance, and environmental protection, making them ideal for industrial, commercial, and high-risk applications where cable safety and operational continuity are critical .
