Industries We Serve — FRP Applications

Optical Fibre Cables — FTTH and Telecom Infrastructure

FRP central strength members are the structural backbone of optical fibre cables. Every loose-tube and tight-buffered OFC cable used in FTTH, telecom, and backbone fibre networks contains one or more FRP rods that carry the mechanical load and protect the glass fibres inside.

Why FRP Rods Are Specified for OFC

• Non-conductive — eliminates risk of electrical interference with fibre signal
• 60–75% lighter than steel wire — reduces cable weight for aerial spans and ADSS applications
• High tensile strength — withstands cable installation tension and long-term mechanical load
• Smooth surface finish — essential for stranding and cable assembly machines at the OFC plant
• UV-resistant resin options available for outdoor aerial cable applications

Submarine and Offshore Cables

Submarine power and communications cables operating at depth require reinforcement elements that combine high tensile strength with resistance to seawater corrosion and hydrostatic pressure. FRP rods are increasingly specified in place of steel wires for shallow-water and inter-island submarine cable projects.

• No corrosion in saltwater environment — eliminates the galvanic degradation that limits steel wire service life
• High tensile strength-to-weight ratio — reduces cable buoyancy compensation requirements
• Compatible with standard armoured cable designs

Electrical Cable Reinforcement

In high voltage and extra high voltage power cables, non-conductive reinforcement is required where steel wire would create eddy currents, galvanic corrosion, or electromagnetic interference. FRP rods are used as:

• Phase reinforcement in XLPE HV cable designs
• Central strength element in submarine power cables
• Armouring layer replacement in chemically aggressive cable burial environments

Duct Rods and Microducts

Duct rods — also referred to as cable duct rodders or microduct strength members — are lightweight, flexible FRP rods used in telecom and utility infrastructure for pushing or blowing cables through conduit systems.

• Continuous lengths spooled on reels — 500 m to 2,000 m per reel depending on diameter
• Diameter range 3 mm – 12 mm for conduit installation applications
• High surface smoothness for reduced friction during cable installation
• Lightweight — enables longer installation spans with less equipment

FRP Rebar — Construction Sector

FRP rebar is a non-metallic reinforcement bar used in concrete structures where steel rebar would corrode — marine infrastructure, water treatment plants, chemical storage facilities, metro tunnels, bridge decks, and coastal construction.

Insulation Rods — Power Sector

FRP insulation rods are used in electrical equipment and power infrastructure where high dielectric strength and thermal resistance are required:

• Transformer bushings and spacers
• Switchgear insulation assemblies
• Overhead line standoff insulators
• Bus bar insulation profiles in switchyards
• Railway overhead electrification fittings
