FRP Fiber Reinforced Plastic Rod Smooth High Modulus For Optic Cables
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.
