1. Determine the Cable Tray Type
Industrial plants typically use these four main types of cable trays:
Industrial Recommendation:
- Power & Control Cables → Ladder or Solid Bottom Tray
- Data & Fiber Optic Cables → Wire Mesh or Perforated Tray
- Harsh Chemical Environments →Stainless Steel or FRP Tray
2. Consider Material & Corrosion Resistance
Industrial plants often have moisture, chemicals, and high temperatures, so material selection is crucial:
Industrial Recommendation:
- Standard Factories → Hot-Dip Galvanized Steel
- Chemical Plants → Stainless Steel 316 or FRP
- Outdoor/High Humidity →Powder-Coated or Aluminum
3. Calculate Load Capacity & Cable Fill
Industrial cables can be heavy, so ensure the tray can support the weight:
Load Capacity Guidelines:
- Light Duty: 50–100 kg/m (control cables)
- Medium Duty: 100–200 kg/m (power cables)
- Heavy Duty: 200–500 kg/m (HV cables, mining plants)
Cable Fill Ratio (NEC/IEC Standards):
- Power Cables → Max 50% fill
- Control Cables → Max 70% fill
- Avoid overloading → Prevents overheating & maintenance issues
Industrial Recommendation:
- Use ladder trays for heavy cables (long spans).
- Use solid-bottom trays where cable protection is critical.
4. Environmental & Safety Factors
Industrial plants have unique challenges:
Corrosion Resistance → Choose stainless steel or FRP in chemical zones.
Fire Protection → Use fire-rated trays (UL/CE certified) in high-risk areas.
Impact Resistance → Heavy-duty trays for mining, oil & gas.
EMI Shielding → Aluminum or steel trays for sensitive electronics.
Industrial Recommendation:
- Oil & Gas → Stainless Steel + Fireproof Coating
- Food & Pharma → Sanitary SS 316 Trays
- Mining & Heavy Industry →Extra-Thick Galvanized Steel
5. Installation & Maintenance Considerations
- Modular Design → Faster installation (e.g., quick-clip systems).
- Accessibility → Open trays (ladder/mesh) for easy cable additions.
- Support Spacing → Typically 1.5m–3m (adjust based on load).
- Expansion Joints → Needed in high-temperature areas.
Industrial Recommendation:
- Pre-plan cable routes to minimize bends and supports.
-Use perforated trays where ventilation & accessibility are key.
Final Checklist for Industrial Cable Tray Selection
1. Type → Ladder / Mesh / Solid / Channel
2. Material → Galvanized / Stainless / Aluminum / FRP
3. Load → Light / Medium / Heavy duty
4. Corrosion → Standard / Chemical-resistant
5. Fire Safety → Does it meet local codes
6. Installation → Easy to assemble & expand
Pro Tip: Consult with us for custom solutions in environments (e.g., high heat, explosive areas).
