Thickness of cable trays in the Philippines

Cable tray thickness in the Philippines varies by material, type, and load requirements, typically ranging from 1.2 mm to 3.0 mm for metal trays, in accordance with PEC 2017 and industry standards.

Standard Thickness Guidelines

Cable trays in the Philippines are generally manufactured from steel, aluminum, or non-metallic materials like PVC. The thickness depends on the tray type and the expected load:

• Ladder-type trays: Commonly used for heavy-duty power cables; steel trays typically have a thickness of 1.6 mm to 3.0 mm, while aluminum trays may range from 1.2 mm to 2.5 mm .
• Perforated or ventilated trays: Designed for medium loads and better airflow; steel thickness usually ranges from 1.2 mm to 2.0 mm .
• Wire mesh trays: Used for light-duty or data cables; thickness is generally 1.0 mm to 1.5 mm .
• PVC trays: Non-metallic trays for corrosion resistance; thickness typically ranges from 2.0 mm to 3.0 mm, depending on size and load .

Compliance and Standards

The Philippine Electrical Code (PEC) 2017, Article 3.92, governs cable tray installations, specifying mechanical support, grounding, and load considerations . While the PEC does not explicitly mandate exact thicknesses, it requires that trays be structurally sufficient to support the installed cables and comply with NEC 392 and UL 568 standards when PEC is silent . Manufacturers in the Philippines, such as RS and AM-PRO, provide trays that meet these standards and offer various thicknesses suitable for industrial, commercial, and IT applications .

Practical Considerations

• Load capacity: Heavier power cables require thicker trays to prevent bending or deformation.
• Environmental factors: Coastal or industrial areas may require galvanized or stainless steel trays with higher thickness for corrosion resistance .
• Installation height and span: Longer spans between supports may necessitate thicker trays to maintain structural integrity. In summary, metal cable trays in the Philippines typically range from 1.2 mm to 3.0 mm in thickness, with the exact value determined by tray type, material, load, and environmental conditions, all in compliance with PEC 2017 and international standards .
