FRP Rod FRP Strength Member For Optical Fiber Cables
FRP Central Strength Member, Insulation Rods are widely used all over the world in most types of optical fiber telecommunication and data cables. The up-to-date pultrusion technology is adopted for making FRP products, so the products have excellent properties.
FRP Rod Features
1) High tensile strength, high modulus, low heat conductivity, low stretch, low expansion, wide range of temperature settings.
2) Insensitive to electric shock, suitable for the area with frequent lightning and raining.
3) Free from chemical corrosion. Compared with metal wire, FRP rod eliminates harmful gas, which can negatively affect cables transmission quality, born chemically by metal and filling gel.
4) Compared with metal wire, FRP rod is of high strength, low weight, excellent insulation and immune to electromagnetic interference.
5) Optical fiber cables with FRP rod are available to be installed tight close to power wire and power units, perfectly insulated, free from induction current interference. The transmission efficiency can be improved accordingly.
6) Smooth surface, stable sizes, easy processing and installation contribute to wide range of FRP strength member application
