Insulation Grade FRP Cable Ladder Pultruded 50mm-1200mm Width UV Stabilized
Product Details
Electrical Insulation Cable Ladder
,Pultruded FRP Cable Ladder
,Insulated Ladder Tray
FRP Cable Ladder Electrical Insulation is supplied where the cable support itself must provide dielectric separation: process plants with live electrical equipment, electrolytic cells, battery rooms and test areas where a metallic tray would compromise the insulation coordination of the installation.
The ladder is produced in pultruded FRP, and also in hot dip galvanized or stainless steel where the project needs mechanical strength with insulating isolation only at the brackets. Widths run from 50 mm to 1200 mm, rail heights 50 mm to 200 mm, rung pitch 225 mm, 300 mm or 450 mm, in 1 m to 3 m modules for congested routes.
In the FRP version the insulation is a material property, not a coating: resistivity is measured to ASTM D257 and IEC 60093 on the finished profile, and the value holds under wet contamination because the resin matrix does not absorb water the way a filled thermoplastic can. There is no tracking path along the surface and no galvanic couple at the fasteners.
The steel version uses the same geometry with insulating standoff brackets and joint plates, which is the practical choice for long spans where the mechanical demand exceeds the composite section. Both versions share the fitting family, so a route can transition between them at a defined boundary.
BENDIN manufactures both versions at up to 100000 m per week across composite and steel lines, with 180 staff and thirty years of cable support engineering. Insulation resistance, rung strength and dimensional accuracy are inspected per batch, and project specific test certificates can be issued.
Minimum order 50 m, 10 to 20 working day delivery, prices on request, pallet packing, terms L/C, T/T or Western Union. Give us the voltage class, the fault level and the environment and we will confirm the material, the isolation arrangement and the support spacing.

Typical Applications- Electrolytic and electroplating plants
- Battery rooms and UPS installations
- High voltage test areas
- Chemical process buildings
- Water and wastewater electrical rooms
Q: Is the insulation affected by washdown?
A: No. Resistivity is a property of the resin matrix and holds under wet contamination, unlike a surface coating that can be breached.
Q: Can I mix FRP and steel on one route?
A: Yes. Both versions share the fitting family, so the route can transition at a defined boundary between wet and dry areas.
Q: What test documents are supplied?
A: Resistivity results per batch, plus load and deflection calculations for the specified span, and project specific certificates where required.
Q: What is the minimum order?
A: Minimum order 50 m, delivery 10 to 20 working days, prices on request.
