Cable trays in South Sudan are available in standard sizes such as 50mm x 25mm, with dimensions generally following international standards for width, depth, and material thickness.

Standard Cable Tray Dimensions

Cable trays are designed with width, depth, length, and material thickness in mind to ensure proper cable fill, heat dissipation, and structural integrity. Common widths range from 50mm to 600mm, while depths typically vary from 25mm to 150mm, depending on the tray type and load requirements. Lengths are usually 2 to 3 meters per section, and material thickness is selected based on the expected load and environmental conditions. Ladder trays, perforated trays, channel trays, and wire mesh trays each have slightly different dimensional priorities, with ladder trays favoring width and side rail height for heavy loads, and wire mesh trays prioritizing flexibility and speed of installation .

Local Availability in South Sudan

In South Sudan, cable trays are available through local suppliers such as Shopit, offering products like galvanized 50mm x 25mm trays, which are suitable for light-duty applications and small cable runs . These trays are typically made from galvanized steel to resist corrosion and ensure durability in local environmental conditions. Other sizes may also be available depending on supplier stock and project requirements .

Sizing Considerations

When selecting cable tray dimensions, it is important to calculate the total cable area based on the outside diameter of each cable, not just conductor size. Most standards, including NEC and IEC practices, limit cable tray fill to a percentage of the usable tray area, commonly around 40%. The usable area is calculated as: Usable Area = Inside Width × Usable Depth This ensures proper spacing, prevents overheating, and allows for future expansion .

Summary

For projects in South Sudan, standard cable tray dimensions such as 50mm x 25mm galvanized trays are commonly used for light-duty applications, while larger widths and depths are available for heavier cable loads. Proper sizing should always be based on cable fill calculations and compliance with international standards to ensure safety and long-term reliability .
