Vertical shaft cable tray tees are typically available in standard widths of 50 mm to 750 mm, with depths ranging from 50 mm to 150 mm, designed to match the main cable tray system for seamless branching.

Standard Widths and Depths

Vertical shaft cable tray tees are manufactured to align with the main cable tray dimensions. Common nominal widths include 50 mm, 100 mm, 150 mm, 200 mm, 300 mm, 400 mm, 500 mm, and 750 mm, while side rail heights (depths) generally range from 50 mm to 150 mm depending on the load and cable type . These dimensions ensure compatibility with ladder, perforated, and wire mesh trays.

Material and Construction

Cable tray tees are made from pre-galvanized steel, hot-dip galvanized steel, stainless steel (304, 316, 316L), aluminum, or powder-coated steel . The choice of material depends on environmental conditions, such as indoor, outdoor, or corrosive environments. The tees are designed to maintain structural integrity while supporting the weight of cables and minimizing deflection.

Design Considerations

• Bend Radius: Vertical tees are designed to maintain the minimum bend radius for cables exiting the tray, preventing damage and ensuring compliance with cable manufacturer specifications .
• Compatibility: Tees are manufactured to match the width and depth of the main tray, allowing smooth branching without reducing cable fill capacity.
• Length: Standard tee lengths are typically 300 mm to 500 mm, but can vary depending on manufacturer and installation requirements .
• Load Capacity: The structural design of tees considers the total cable load, environmental loads, and support spacing, ensuring safe installation in vertical shafts .

Summary

When selecting a vertical shaft cable tray tee, ensure the width and depth match the main tray, the material suits the environment, and the bend radius accommodates the cables. Standard widths range from 50 mm to 750 mm, depths from 50 mm to 150 mm, and lengths from 300 mm to 500 mm, providing flexibility for industrial, commercial, and data center installations .
