Trough-type straight-through cable tray models

Straight-through trough type cable trays are rigid, continuous systems designed for supporting and protecting electrical and data cables along straight routes, available in various materials, sizes, and configurations.

Overview

A trough type cable tray is a continuous structure with side rails and either a solid or ventilated bottom, ideal for straight cable runs where minimal sag and maximum protection are required . These trays are widely used in industrial plants, commercial buildings, data centers, airports, and power plants due to their robust design and modularity .

Key Models and Examples

1. TTS Green Trough Straight Series
   • Designed for straight routes with standard or divider options.
   • Available in sizes: G90, G135, 150B, 200B, 300B, 430C .
   • Made from 100% recycled polymer, UV-resistant, and suitable for -40°C to +80°C.
   • Modular design allows on-site modifications without 45° bends.
   • Applications: highways, rail, renewable energy, stadiums, airports, and data centers .
2. ABB T&B Cabletray Straight Sections
   • Available in aluminum or steel with various finishes.
   • Compatible with a wide range of fittings, covers, and accessories.
   • Designed for easy cable installation and future system expansion .
3. Legrand Cablofil Steel Trough Trays
   • Provides high strength and security, limiting cable access.
   • Available in multiple widths and heights, with solid or ventilated bottoms.
   • Suitable for environments requiring dust and moisture protection .

Features to Consider

• Material: Steel trays offer higher load capacity; aluminum and polymer trays are lighter and corrosion-resistant .
• Bottom Type: Solid bottoms provide maximum protection; ventilated bottoms allow heat dissipation and reduce weight .
• Modularity: Many models allow easy expansion, T-junctions, and gradients without replacing the entire system .
• Load Capacity: Depends on material, gauge, support spacing, and tray width; exceeding limits can cause structural failure .
• Environmental Resistance: Some trays are resistant to UV, acid rain, salt, and extreme temperatures, suitable for outdoor or harsh environments .
• Compliance: Ensure trays meet relevant standards such as NEC, IEC, ASTM, or NEMA for safety and reliability .

Applications

Straight-through trough trays are ideal for long, uninterrupted cable runs where protection, organization, and accessibility are critical. They are commonly used in industrial plants, commercial buildings, airports, stadiums, and renewable energy installations . By selecting the appropriate model, material, and configuration, engineers can ensure efficient installation, long-term durability, and compliance with industry standards.
