FRP cable management includes pultruded cable trays and trench covers used to support and protect electrical cables. This page explains how to select the appropriate product for your installation.
Product Family Overview
FRP cable trays are manufactured by pultrusion, aligning continuous glass fibers in the direction of the span. They may be ladder, solid‑bottom, or perforated. Trench covers are often solid or grated. Resin systems include polyester, vinyl ester, and flame‑retardant formulations.
Selection Considerations
- Dielectric insulation – required for electrical safety.
- Cable load capacity – determines tray size and support spacing.
- Flame retardancy limits – select resin accordingly.
- Corrosive exposure – dictates resin system.
Frequently Asked Questions
Are FRP cable trays non‑conductive?
FRP is generally non‑conductive, but the final electrical properties depend on the resin and fiber content. For critical electrical isolation, the specific product configuration should be evaluated.
Can FRP cable trays be modified on site?
Yes, but field cutting exposes glass fibers. Cut edges must be sealed with a compatible resin to maintain corrosion resistance.
