Types of cable trays in the Philippines

Common cable trays in the Philippines include ladder, perforated, wire mesh, and solid-bottom types, made from galvanized steel, stainless steel, aluminum, or PVC.

Types of Cable Trays

1. Ladder Cable Trays: Feature two side rails connected by rungs, providing maximum ventilation and easy access for tying down cables. They are ideal for long spans and heavy power cables in industrial and commercial installations .
2. Perforated Cable Trays: Have a ventilated bottom with side rails, offering more support than ladder trays. They are commonly used for power and instrumentation cables .
3. Wire Mesh Cable Trays: Constructed from welded stainless steel wires forming a basket-like structure. These are lightweight and suitable for telecommunications, low-voltage, and fiber optic cables .
4. Solid-Bottom Cable Trays: Fully enclosed trays that protect cables from environmental factors. They are used where cable protection is critical, though they limit access for maintenance .

Materials and Finishes

Cable trays in the Philippines are typically made from galvanized steel, stainless steel, aluminum, or PVC, chosen for durability and corrosion resistance in humid or coastal environments. Hot-dip galvanizing is commonly used to enhance corrosion protection .

Applications and Compliance

Cable trays are widely used in industrial, commercial, telecommunications, and energy sectors. They provide structured pathways for power, control, and communication cables, allowing easy installation, maintenance, and future expansion. In the Philippines, cable tray installations must comply with Article 3.92 of the Philippine Electrical Code (PEC) 2017, which governs cable fill limits, grounding, support, and ampacity derating .

Local Suppliers

Leading cable tray manufacturers and suppliers in the Philippines include RMRE Electric, LJ Industrial, and Gentec Group, offering ladder, perforated, solid-bottom, and wire mesh trays. Many local products comply with ISO and IEC standards and can be customized for specific project requirements, including size, coating, and design .

Advantages

• Easy installation and maintenance compared to conduit systems
• Enhanced airflow for heat dissipation
• Flexibility for future cable additions or modifications
• Protection against physical damage and environmental factors These features make cable trays a preferred choice for modern electrical installations in the Philippines .
