China Suppliers Factory for KFRP Strength Members in Optical Cables - Lightweight, High Strength Reinforcement Solutions
Product Introduction
Optical cable reinforcement is an important component of optical cable, generally placed in the center of the optical cable, its role is to support the optical fiber unit or optical fiber bundle, improve the tensile strength of the optical cable. Traditional optical cables use metal reinforcements. Non-metal reinforcement parts with their own light weight, high strength, corrosion resistance, long life advantages are more and more used in various optical cable.
KFRP fiber cable reinforcement core (aramid fiber) is a new type of high performance composite material, which is made by pultrusion process after mixing resin as matrix material and aramid fiber as reinforcement material. KFRP cable reinforcement core (aramong fiber) overcomes the defects of traditional metal cable reinforcement parts, in addition to excellent corrosion resistance, lightning resistance, electromagnetic field interference, high tensile strength advantages, than GFRP glass fiber reinforcement core flexibility is stronger, not easy to break, can better protect the fiber, especially suitable for direct introduction from outdoor indoor occasions, It is widely used in inlet network and indoor wiring.
KFRP Features & Advantages
(1) Compared with GFRP, KFRP has lower density, lighter weight, higher tensile strength and modulus than GFRP, low extension, low expansion, and wide temperature range;
(2) Non-metallic materials are not sensitive to electric shock, lightning protection, excellent insulation performance, free from electromagnetic interference, suitable for lightning, rainy climate environment;
(3) Chemical corrosion resistance, compared with the metal core, the KFRP reinforced core will not produce gas caused by the chemical reaction between the metal and the ointment and affect the fiber transmission performance;
(4) The cable with KFRP reinforced core can be installed next to the power line and the power supply device, and will not be interfered by the induced current generated by the power line or the power supply device;
(5) KFRP has excellent flexibility, better bending performance than GFRP, is not easy to be broken, stable size, easy to process and lay, can make indoor cable structure compact and beautiful, especially suitable for access network and complex environment small space wiring;
(6) Impact resistance and fracture resistance, KFRP reinforced core has ultra-high tensile strength, after being accidentally broken, its tensile strength remains above 1300MPa, the modulus remains unchanged, and it will not puncture the protective sleeve and damage the optical fiber.

Frequently Asked Questions (FAQ)
What is a KFRP fiber cable reinforcement core?
KFRP (Kevlar Fiber Reinforced Polymer) is a high-performance composite material made by a pultrusion process, mixing resin as a matrix and aramid fiber as a reinforcement material. It is used in the center of optical cables to support the fiber and improve tensile strength.
What are the main advantages of KFRP over traditional metal reinforcements?
KFRP overcomes the defects of metal cores by offering excellent corrosion resistance, lightning resistance, and immunity to electromagnetic interference. It is lightweight, non-metallic, and will not produce gas from chemical reactions that could affect fiber transmission.
How does KFRP compare to GFRP (Glass Fiber Reinforced Polymer)?
Compared to GFRP, KFRP has a lower density, lighter weight, higher tensile strength, and higher modulus. It also offers better flexibility, making it less prone to breaking and ideal for compact indoor wiring and complex environments.
Is KFRP safe to install near power lines?
Yes. Because KFRP is made of non-metallic, highly insulating materials, cables reinforced with it can be installed next to power lines and devices without being interfered with by induced currents.
What is the standard delivery length and diameter range for KFRP?
The standard diameter range is between Φ0.40mm and Φ5.00mm. For diameters ranging from 0.40mm to 3.00mm, the standard delivery length is ≧25km. Custom sizes and lengths can also be produced upon request.
How should KFRP reinforced cores be stored properly?
They should be stored in a temperature range of -40°C to +60°C. They must be protected from moisture and long-term rain or sun exposure. The cable trays should not be placed flat, stacked high, or subjected to mechanical damage.
