Different Specifications of Cable Tray Funnel Models

Funnel-shaped cable trays are specialized cable management systems designed to guide cables through transitions or constricted areas, available in various materials, sizes, and configurations to meet load and environmental requirements. OverviewFunnel-shaped cable trays are typically used to direct cables from a wide entry point to a narrower exit, or to manage cable transitions between different tray types or equipment. They are often fabricated from steel, stainless steel, aluminum, or fiberglass, depending on environmental conditions and load requirements.

These trays are designed to maintain mechanical support, strain relief, and proper airflow to prevent overheating.

Materials and Finishes

Galvanized Steel: Offers corrosion resistance for indoor and outdoor applications. Stainless Steel: Suitable for harsh or chemical environments. Aluminum: Lightweight and corrosion-resistant, ideal for industrial or commercial installations.

Fiberglass: Non-conductive and corrosion-resistant, used for light wiring or control cables. Finishes: Zinc coating, epoxy coating, or powder coating for additional protection. Dimensions and Load CapacityFunnel-shaped trays are available in various widths and depths, often matching standard ladder or channel tray sizes for compatibility.

Load capacity depends on tray material, thickness, and support span. Common designations follow NEMA VE-1 standards for metal cable trays, ensuring structural integrity and safety. Widths typically range from 100 mm to 600 mm, with depths from 50 mm to 150 mm, but custom sizes are also available.

Models and ConfigurationsLadder-Type Funnel Trays: Feature side rails with rungs for airflow and easy cable support, suitable for heavy power cables.

Solid-

Bottom Funnel Trays: Provide full support for sensitive or small-diameter cables, preventing dust or debris accumulation. Ventilated or Perforated Funnel Trays: Allow heat dissipation and reduce weight, ideal for data centers or telecommunication rooms. Custom Fittings: Horizontal and vertical elbows, reducers, tees, and branches can be integrated to create funnel transitions.

Standards and ComplianceFunnel-shaped cable trays are designed to comply with UL, NEMA, and IEC standards, ensuring safety, fire resistance, and mechanical performance.

E marking may apply for European installations, and trays are often tested for load, corrosion, and electrical insulation.

Applications

Transitioning cables from wide distribution trays to narrower equipment entry points. Managing high-density cable runs in data centers, industrial plants, or commercial buildings. Integrating with ladder, channel, or wire mesh trays for complex routing.

Supporting power, control, instrumentation, and communication cables while maintaining airflow and strain relief. Funnel-shaped cable trays provide a flexible, safe, and efficient solution for guiding cables through constrained or complex pathways, with multiple material, size, and configuration options to suit diverse industrial and commercial applications.
