Non Conductive FRP Cable Ladder Fire Retardant Resin 50mm-200mm Depth Build

FRP Cable Ladder Non-Conductive is the route specified where an electrically insulating support is a safety requirement rather than a preference: substations, test bays, electrochemical plants and areas where maintenance staff work near energised conductors and a steel tray would create an unintended path.

The ladder is pultruded from E glass in a fire retardant resin system with a dielectric strength chosen for the application, in widths from 50 mm to 1200 mm, rail heights of 50 mm to 200 mm and rung pitch of 225 mm, 300 mm or 450 mm. Stainless fasteners are used only where they do not bridge the insulation requirement.

Non conductivity is verified rather than assumed: surface and volume resistivity are tested to ASTM D257 and IEC 60093, and the value is retained even under wet conditions, which is the case that matters in a washdown or an outdoor substation. A galvanized steel ladder in the same location would need bonding at every joint.

The composite also removes the corrosion maintenance loop. There is no zinc to consume, no paint to renew and no rust staining on the surrounding structure, so a route that would need inspection and touch up every few years becomes a fit and forget item in the maintenance budget.

BENDIN produces FRP ladder at 10000 m per week with 180 staff and thirty years of cable support engineering, exporting 60 to 70 percent of output to utilities, chemical plants and infrastructure contractors. Resistivity, resin cure and rung strength are checked on every batch before shipment.

Minimum order 100 m, delivery on request, 4 to 25 USD per metre, pallet packing, terms L/C, T/T or Western Union. Tell us the voltage class, the environment and the load and we will confirm the resin system, the wall thickness and the support spacing.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

Q: How is non conductivity verified?
A: Surface and volume resistivity are tested to ASTM D257 and IEC 60093 on the finished profile, and the values hold under wet contamination.

Q: Does it need earthing or bonding?
A: No. The material does not conduct, so no bonding is required, which removes a whole set of joints and inspections from the installation.

Q: Can a steel version be supplied with insulation?
A: Yes. Where mechanical demand is higher we supply a galvanized or stainless ladder with insulating standoff brackets and joint plates.

Q: What is the minimum order?
A: Minimum order 100 m, prices from 4 to 25 USD per metre, pallet packing and L/C, T/T or Western Union terms.
