Fiber Reinforced Plastic FRP Rods For Fiber Optic Cables
FRP stength member (FRP Rod) is a new type of high-performance
engineering composite material prepared by pultrusion process with
resin as the matrix material and glass fiber as the reinforcing
material.It is a new type of high performance non-metallic cable
reinforcement. FRP strength member overcomes the defects of
traditional metal cable reinforcements, has excellent corrosion
resistance, lightning resistance, electromagnetic field
interference resistance, high tensile strength, light weight,
environmental protection, energy saving, etc., and is widely used
in a variety of fiber optic cable.
1) not sensitive to the lightning strike, applied to the areas
which are common with frequent lightning and rain;
2) Not obstructed by induced current and can be installed close to
the power unit and device;
3) No harmful gas that would affect the optical transmission
indicators;
4) Has the characteristics of high tensile and light weight;
5) bullet-proof, ant-proof and anti-tooth proof.

• Light Weight & Excellent Tensile Strength
• Prevent Cable Buckling
• Most Suited for Multi-Loose Tube, Uni Tube, Slotted Core & Ribbon
Cable Designs
• Used as Central or Peripheral Reinforcement in Fibre Optic Cables
• Dual Advantage : Reinforcement during Installation as well as
Reduce Stress on Signal Carrying Optic Fibre /Conductor
• Prevent Sagging in Aerial Installation
• Cost Effective Solution as a Strength Member
Features:
* High tensile strength, high modulus, low thermal conductivity,
low elongation, low expansion, and wide temperature range;
* Non-metallic materials are not sensitive to electric shock, and
are suitable for areas with multiple lightning and rainy weather
conditions
* Chemical resistance, compared with the metal core, the GFRP
reinforcing core does not affect the fiber transmission index
* The fiber optic cable using the GFRP reinforcing core can be
installed next to the power line and the power supply device, and
is not interfered by the induced current generated by the power
line
* Smooth surface, stable size, easy to process and lay, and the
application range is wide.
