Technical Specifications for Aluminum Cable Ladders

Aluminum cable ladders are a common solution in the field of cable management. Understanding the technical requirements for aluminum cable ladders is crucial for designing and implementing cable management systems. Below is an interpretation of some technical standards for aluminum cable ladders to help you gain a deeper understanding of the product characteristics.

Table 1: Technical Requirements for Aluminum Cable Ladders
Product Name Aluminum Cable Ladder
(Divided into 31/30 mm × 45 mm and 50 mm × 50 mm by profile cross-section specifications)
Performance Requirements for Anodized Film
  • The thickness of the anodized film should meet the AA10 grade (average thickness ≥ 10 um, minimum local thickness ≥ 8 um)
  • Conduct the coating adhesion test according to GB9286-1998 Paints And Varnishes--Cross Cut Test For Films. The coating on all samples should be 100% adhered.
Conduct the salt spray test according to GB/T 2423.17 Environmental Testing For Electric And Electronic Products – Part 2: Test Method – Test Ka: Salt Mist. After 96 hours, the results should not be lower than grade 2 specified in the standard (slight change in gloss and color).

  • The average load per meter is related to parameters such as span, cable ladder width, crossbar spacing, steel plate thickness, and cross-sectional dimensions. The above load data is for reference and can be adjusted according to the actual project conditions.
  • The cable ladder should be straight, without obvious twisting or warping. It should be parallel or perpendicular to the top of the cabinet, with a horizontal deviation of no more than 2 mm per meter. Vertical cable ladders should remain vertical to the ground without any inclination, with a vertical deviation of no more than 3 mm.
Profile Thickness Frame profile thickness ≥ 2 mm
Crossbar profile thickness ≥ 4 mm
Crossbar Spacing The material size of the crossbar should be consistent with the main material, and the crossbar spacing should be 250–350 mm
Profile Requirements
  • For cable ladders with a width of 800–1200 mm, 50 profiles (50×50 mm) should be used.
  • For cable ladders with a width of 200–800 mm, 45 profiles (45 × 31 mm / 45 × 30 mm) should be used.
