Recommended Arbitrary Angle Cable Trays

For routing cables at arbitrary angles, wire mesh, perforated, and ladder cable trays with specialized bend fittings are recommended for flexibility, safety, and compliance.

Cable Tray Types Suitable for Arbitrary Angles

Wire Mesh Cable Trays – Lightweight and highly flexible, ideal for complex routing and non-standard angles. They allow easy modifications and quick installation, making them suitable for fiber optic and low-voltage cables (ABB Technical Guide, Dacksa ). Perforated Cable Trays – Provide moderate flexibility with a perforated base for airflow and cable support.

They can accommodate angled bends using compatible fittings and are suitable for structured cabling systems (Dacksa ). Ladder Cable Trays – Best for heavy-duty power cables and high-heat environments. Horizontal and vertical bends can be achieved using T-pieces, crossovers, and angled fittings (BEAMA Guide ).

Fittings and Components for Arbitrary Angles

Horizontal and Vertical Bends – Allow smooth directional changes without stressing cables.

T-

Pieces and Crossovers – Enable branching or intersecting cable runs at various angles. Reductions and End Closures – Adjust tray width or terminate runs safely (OBO CMS Guide ). Custom Angle Fittings – Some manufacturers provide adjustable or pre-fabricated fittings for non-standard angles.

Material Considerations

Galvanized Steel – Durable and corrosion-resistant for general industrial use. Stainless Steel (AISI 316L) – Ideal for harsh or chemical environments. Aluminum – Lightweight, corrosion-resistant, and easy to form for angled installations.

Fiberglass Reinforced Plastic (FRP) – Suitable for high-corrosion areas like chemical plants or marine environments (ABB Technical Guide, Dacksa ).

Installation Best Practices

Ensure supports are installed at recommended intervals to prevent sagging and maintain mechanical stability. Use fittings designed for the specific tray system to maintain safety and compliance with standards such as DIN EN 61537, NEC, and IEC. Maintain proper cable arrangement to reduce electromagnetic interference and allow heat dissipation.

Verify that the tray and fittings are compatible with the cable type, load, and environmental conditions (BEAMA Guide, Dacksa ).

Summary

For arbitrary angle routing, wire mesh trays offer the highest flexibility, while perforated and ladder trays provide structural support for heavier cables. Using appropriate bend fittings and high-quality materials ensures safe, compliant, and durable installations. Always follow manufacturer guidelines and industry standards to optimize performance and longevity.
