The Difference Between FRP And KFRP, The Central Reinforcement Of Optical Cable And Fiber Drop Cable


FRP, fiber reinforced composite plastic, is the abbreviation of English (Fiber Reinforced Polymer). Outdoor optical cables often use FRP as the central reinforcement; now the use of leather cables is more and more widely used. In addition to using FRP as the central reinforcement, the leather cables also use KFRP as the central reinforcement.

The difference between strengthen member FRP & KFRP in fiber drop cable

FRP (glass fiber) Has The Following Characteristics:

(1) Lightweight and high-strength relative density is between 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength can be compared with high-grade alloy steel . Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure vessels, and other products that need to reduce their own weight. The tensile, flexural and compressive strengths of some epoxy FRP can reach more than 400Mpa.

(2) Good corrosion resistance    FRP is a good corrosion-resistant material, and has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and various oils and solvents. It has been applied to all aspects of chemical corrosion protection, and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

(3) Good electrical properties    is an excellent insulating material used to make insulators. It can still protect good dielectric properties under high frequency. It has good microwave permeability and has been widely used in radomes. and many more.


KFRP (polyester aramid yarn):

Aramid fiber reinforced fiber optic cable reinforcement core (KFRP) is a new type of high performance non-metallic fiber optic cable reinforcement core, which is widely used in access networks.

Lightweight and high strength: Aramid fiber reinforced fiber optic cable reinforced core has low density and high strength, and its specific strength and specific modulus far exceed those of steel wire and glass fiber reinforced optical cable cores;

Low expansion: The aramid fiber reinforced optical cable reinforced core has a lower coefficient of linear expansion than the steel wire and glass fiber reinforced optical cable reinforced core in a wide temperature range;

Impact resistance and fracture resistance: The aramid fiber reinforced fiber optic cable reinforced core not only has ultra-high tensile strength (≥1700MPa), but also impact resistance and fracture resistance, and can maintain a tensile strength of about 1300MPa even when it is broken;

Good flexibility: The strength of the aramid fiber-reinforced optical cable is light and easy to bend. Its minimum bending diameter is only 24 times the diameter. Make the indoor optical cable structure compact, beautiful, excellent bending performance, especially suitable for wiring in complex indoor environment.
