Fibre Reinforced Plastic Rod For Optical Fibre Cables

The FRP strength member for fiber optic cables is specifically designed for total insulated application. In shape of round rod or flat ribbon, the FRP strength member features perfect size stability and smooth surface. Long continuous length (50km) without splice greatly enhances continuous productivity in cabling operations.

The structural strength of optical cable is an important index of the mechanical properties of optical cable. As one of the structural components of fixed optical cable, the FRP reinforcing core plays an important role in strengthening the tensile and compressive capacity of optical cable.
FRP glass fiber reinforced core, as a kind of structural strengthening element of non-metallic fiber optic cable, is widely accepted and used by the fiber optic cable industry. It is a non-metallic bearing core with good price and performance generally recognized by the fiber optic cable industry at home and abroad. To produce qualified FRP, the key lies in the reasonable selection of reinforcement materials (glass fiber), base materials (resin) and curing process.

• High tensile strength, high ratio of strength/weight, low specific gravity, only 1/4 of steel wire, low stretch, low expansion, wide range of temperature settings.
• Insensitive to electric shock, suitable for the area with frequent lightning and raining.
• Free from chemical corrosion. Compared with metal wire, FRP strength member eliminates harmful gas, which can negatively affect cables transmission quality, born chemically by metal and filling gel.
• Optic cables with FRP strength member 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.
• Stable size, lower weight and higher strength than metal wire make optic cables easy processing and easy installation.
