Cable tray with shielded cable duct

Cable trays with shielded cable ducts provide organized, safe, and efficient routing for power, control, and data cables while protecting them from mechanical damage and electromagnetic interference.

Overview

Cable trays are structural systems designed to support and route electrical and communication cables. When dealing with shielded cables, which are sensitive to electromagnetic interference (EMI), it is important to select trays that maintain cable integrity and allow proper grounding. Shielded cable ducts can be integrated into perforated, mesh, or solid cable trays to provide additional protection and separation from other electrical lines .

Types of Cable Trays Suitable for Shielded Cables

• Perforated Cable Trays: These trays feature dense perforations for ventilation, preventing heat buildup in shielded cables while maintaining mechanical protection. They are lightweight, durable, and compliant with IEC61537 standards, making them suitable for control and power cable routing .
• Mesh or Wire Cable Trays: Open-structure trays allow easy installation, inspection, and maintenance. They are ideal for data centers, server rooms, and industrial automation environments. Stainless steel mesh trays resist corrosion and are easy to clean, which is beneficial in hygienic or industrial settings .
• Solid or Covered Trays: For environments requiring maximum EMI shielding, solid or covered trays can be used to enclose shielded cables fully, reducing interference from nearby electrical equipment .

Key Features and Benefits

• Cable Protection: U-shaped edges or covered designs prevent cable damage during installation and operation .
• Heat Dissipation: Perforated designs allow airflow, reducing the risk of overheating in high-density cable installations .
• Ease of Installation: Modular systems with snap-together components or pre-fabricated kits simplify assembly and reduce labor costs .
• Compliance and Safety: Many cable trays meet international standards (e.g., IEC61537) and certifications (e.g., DNV), ensuring safe and reliable cable management .
• Adaptability: Cable trays can be mounted on walls, ceilings, raised floors, or equipment racks, and can accommodate vertical drops or horizontal transitions without compromising cable bend radius .

Applications

• Industrial Automation: Machine power cables and control lines benefit from organized routing and EMI protection .
• Data Centers and Server Rooms: Shielded network cables require separation from power lines to prevent signal interference .
• Commercial and Utility Installations: Power distribution, control, and communication cables can be safely routed in large-scale facilities .

Material Options

• Steel (Galvanized or Stainless): Provides mechanical strength and corrosion resistance.
• Aluminum: Lightweight and corrosion-resistant, suitable for overhead installations.
• Engineering Plastics (e.g., Noryl): Non-conductive, easy to install, and ideal for fiber optic or sensitive low-voltage cables . Selecting the right combination of cable tray type, material, and shielding ensures optimal performance, safety, and longevity for shielded cable installations in demanding environments.
