Cable tray with two-sided transverse funnel

A cable tray with two-sided transverse rungs is essentially a ladder-type tray designed for robust cable support, ventilation, and easy installation, often used in industrial and commercial applications.

Structure and Design

A ladder cable tray consists of two longitudinal side rails connected by individual transverse members or rungs . In the case of a two-sided transverse funnel, the tray may feature rungs or supports on both sides, forming a funnel-like structure that guides cables into the tray while providing solid side rail protection and structural integrity . This design allows for:

• Maximum ventilation for heat-producing cables, such as power cables .
• Smooth cable installation and easy access for adding or removing cables in the future .
• Enhanced mechanical strength, suitable for long support spans and high vibration environments .

Materials and Finishes

Cable trays are available in a variety of materials to suit different environments:

• Aluminum – lightweight and corrosion-resistant
• Steel – standard or hot-dip galvanized for durability
• Stainless steel – for corrosive or high-humidity environments
• PVC-coated steel or aluminum – for additional protection against chemical exposure Surface finishes may include pre-galvanized, powder-coated, or painted options to enhance durability and aesthetics .

Applications

Two-sided transverse ladder trays are ideal for:

• Industrial construction such as power plants, paper mills, and manufacturing facilities .
• Control and signal cable routing in commercial buildings and switchgear centers .
• High-density cable installations where multiple cables need to be organized and supported efficiently .

Installation Considerations

• Rung spacing typically ranges from 6" to 18", depending on cable size and load requirements .
• Load depths vary from 3" to 7" to accommodate different cable bundles .
• Fittings such as elbows, tees, and reducers allow directional changes and width adjustments while maintaining structural integrity .
• Prefabricated splice plates or swaging methods ensure strong mechanical and electrical connections between tray sections .

Advantages

• Improved cable management with clear separation and guidance.
• Enhanced airflow to prevent overheating of power cables.
• Durability and reliability for long-term industrial use.
• Ease of maintenance and future cable additions or modifications. In summary, a cable tray with two-sided transverse rungs or funnel is a specialized ladder-type tray that combines structural strength, ventilation, and cable guidance, making it suitable for demanding industrial and commercial electrical installations .
