Dimensions of Bissau Trough Cable Trays in Southeast Asia

Bissau trough (perforated) cable trays typically follow standard widths of 100–600 mm, depths of 50–150 mm, and lengths of 2.44–3.66 meters, with material thicknesses ranging from 1.2 to 2.5 mm, depending on load and application.Standard Widths and DepthsPerforated or trough cable trays are designed to provide continuous support for cables while allowing ventilation. Common widths range from 100 mm to 600 mm, with the nominal inside usable width slightly smaller than the overall tray width due to side rail thickness . Tray depths (side rail heights) typically range from 50 mm to 150 mm, which affects vertical stacking capacity and heat dissipation . Wider trays are preferred for high-power or solar DC runs to reduce cable stacking and heat concentration.Standard LengthsCable trays are manufactured in straight sections to simplify installation. Typical lengths for trough trays are 2.44 meters, 3.0 meters, and 3.66 meters, which are standard across Southeast Asia and compatible with most fittings and supports . Custom lengths may be available upon request for specific project requirements.Material and ThicknessBissau trough trays are generally made from aluminum alloy, hot-dip galvanized steel, or stainless steel (304/316L) . Material thickness ranges from 1.2 mm to 2.5 mm, depending on the load capacity and span requirements. Thicker materials provide higher structural strength and allow longer support spans without deflection .Load and CompliancePerforated cable trays are designed to comply with IEC 61537, NEMA VE 1-2017, and NEC standards, ensuring safe cable support, proper heat dissipation, and long-term durability . Support spacing is typically 1/4 of the tray span to minimize deflection and stress at splice locations .SummaryFor Southeast Asian installations, Bissau trough cable trays generally conform to the following dimensions:Width: 100–600 mmDepth: 50–150 mmLength: 2.44 m, 3.0 m, 3.66 mMaterial Thickness: 1.2–2.5 mmMaterials: Aluminum, galvanized steel, stainless steel These dimensions provide flexibility for industrial, commercial, and renewable energy projects while ensuring compliance with international standards and safe cable management practices.
