FRP - Fiber Reinforcement Plastic

ISINOX FRP Rod is manufactured using latest and precise technology with fiber and high heat resistant, proprietary resin system ISINOX technology allows higher glass content and higher heat resistant product, leading to higher LASE values and longer life. It is available in various coatings including, EAA and HDPE, which allows easy handling and adhesion with jacketing material. Hard coating provides a very smooth surface suitable for standard loose tube cables.

ISINOX FRP Rod is available from 0.30 mm to 6.0 mm diameter in increment of 0.1 mm with very close dimensional tolerances. It has an added advantage of low bend radius with high torsional strength. It is most suited for loose tube, uni tube, aerial drop cable, ADSS cable, slotted core, ribbon cable & is typically used as central or peripheral reinforcement in fiber optic cables. The product is capable to handle very high production speeds and longer cable lengths Long continuous standard lengths FRP rod, up to 100 Km. per Spool, improves productivity at the factory floor.

TECHNICAL DATA SHEET

The Telecommunication Grade Fibre Reinforced Plastic (FRP) Rod is produced from Glass Roving reinforced with the RMO plastic resin, manufactured by a continuous drawing process (Pultrusion). It is central strength member of Optical Fibre Cable and provides tensile strength to the cable, protecting it during installation and its rigidity prevents cable buckling during the life of the cable.
