Volume (V)=200×100×2×3000 mm3 = 120,000,000 mm3 Converting to cubic meters: 120,000,000 mm3 = 0. 12 m3 Then, calculate the weight: Weight=7. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned. The Cable Tray Weight Calculation involves considering various factors, including tray specifications, material, and thickness. In this guide, we'll walk you through the step-by-step process for calculating cable tray weight, while providing examples for both channel trays and ladder trays. For solid and perforated trays, it treats the tray as a formed sheet: Developed sheet width per meter: Dev = W + 2H + 2R Metal volume per meter: V = Dev × t × 1 × (1 − Open%) Weight per meter: kg/m = V ×. Perforated cable tray with hinged cover, made of Sendzimir galvanized steel. The hinged system is composed of a standard C5 straight section, two hinges and a copper braid for equipotential connection.
