Cable filling rope is a widely used rope material that plays a very important role in cable manufacturing. With the continuous progress of technology, cable filling ropes are also constantly evolving. This article will explore the development process of cable filling ropes from a historical perspective.
Introduction: Electric wires and cables play a crucial role in modern society. From home to industry, transportation to communication, cables are everywhere, providing convenience for our lives. The composition of cables has many parts, among which I will mainly introduce the content of cable filling ropes.
The Origin of Cable Filling Rope
The origin of cable filling ropes can be traced back to the early 19th century. At that time, it was found that filling some rope materials inside the cable could enhance the insulation performance and mechanical strength of the cable, thereby improving its service life and performance. Initially, people mainly used natural fibers as filling materials, such as hemp rope, cotton rope, etc. The advantages of these natural fiber filled ropes are their low cost, durability, and high tensile strength, but the disadvantages are strong water absorption, flammability, and susceptibility to corrosion.
The emergence of synthetic fiber filled ropes
With the development of chemical synthesis technology, synthetic fiber filled ropes have begun to enter people's vision. In the first half of the 20th century, synthetic fiber filled ropes gradually replaced the position of natural fiber filled ropes. The advantages of synthetic fiber filled ropes are high tensile strength, damage resistance, corrosion resistance, non water absorption, etc., and they can be customized according to different needs. At present, the commonly used synthetic fiber filling ropes mainly include polyester fiber, polyamide fiber, and polypropylene fiber.
Structural optimization of cable filling rope
With the rapid development of industries such as power and communication, the performance requirements for cable filling ropes are also increasing. In order to meet these requirements, people have begun to optimize the structure of cable filling ropes. On the one hand, by changing the material composition and structural form of the filling rope, its tensile strength, wear resistance, and corrosion resistance can be improved. On the other hand, by changing the cross-sectional shape and size of the filling rope, the insulation and conductivity performance of the cable can be improved.
So, cable filling ropes play an important role in wire and cable systems, filling the gaps inside the cable and giving it good flame retardant properties. Let me explain in detail the function of cable filling rope and the reason for adding flame retardants.
1. Fill the internal gaps of the cable: The cable is usually composed of multiple wires twisted together, with each group of wires insulated from each other and twisted around a center to form a whole. In order to maintain the roundness and structural stability of the cable, filling ropes are used to fill the gaps between the wires. This helps to make the cable shape neat and improve the roundness of the finished cable.
2. Flame retardant performance improvement: The wire and cable system faces the risk of fire and explosion during operation. Adding flame retardant filling ropes can effectively reduce this risk. Flame retardants can prevent the spread of flames and reduce the probability of fire accidents. For flame-retardant cables, the filling rope itself should be made of flame-retardant material to further enhance the flame retardant performance of the finished cable.
3. Durability and damage resistance: When using flame-retardant PP material, the filling rope can maintain stable physical properties in various harsh environments. This helps to improve the durability and damage resistance of cables. Flame retardant PP materials have excellent flame retardant properties, which can effectively prevent flame spread and extend the service life of cables.
It can be seen from this that adding flame retardants to the filling rope is crucial. Qibo Technology also has flame retardants added to the filling rope, which meets UL94 standards and can make the filling rope resistant to high temperatures and continuously thread.
