How to Choose the Right Cable Tray for Industrial Plants

Selecting the appropriate cable tray for industrial environments requires careful consideration of load capacity, material, corrosion resistance, cable type, and installation conditions. Below is a step-by-step guide to help you make the choice.  

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
