ROD FRP Strength Member GRP For Fiber Optic Cables Plywood Reel
FRP ROD FRP Strength Member GRP Strength Member For Fiber Optic Cables
FRP/GRP Rod Strength Member is to use epoxy resin as foundation combined with the strength of glass fiber through pultrusion technology to produce a new type of high performance non-metallic composite material. Without drawbacks of traditional metallic strength member, FRP strength member features excellent anti-corrosion, electromagnetic interference free, high tensile strength, low weight, saving energy and environmentally friendly, which are now widely used in various optical fiber cables.

1. Insensitive to lightning strike, it is suitable for the area with frequent lightning and rain.
2. Free from induction interference, it can be installed close to the power line and electronic devices.
3. Corrosion free, the FRP eliminates harmful gas produced by the chemical reaction of metal and ointments which can negatively affect the cable’s transmission quality.
4. Light weight and high strength, low density and high ratio of strength/weight;
5. FRP strength member for optical cable is bullet-proof and rodent-proof.
