What are the types of braided layer structures for bending resistant drag chain cables?

1. Fiber woven layer

The fiber braided layer is relatively lightweight, which can protect the insulation layer from erosion by light, heat, humidity, low temperature, acid and alkali gases, as well as external mechanical damage. For bending resistant drag chain cables, the fiber braided layer is often located in the middle of the protective layer to enhance its tear resistance strength. Adding a woven layer of fibers such as cotton yarn and linen to the middle of a rubber or plastic protective layer to improve the strength of the protective layer.

2. Metal braided layer
The metal used in the metal braided layer is mainly copper wire and steel wire. The steel wire braided layer mainly serves as a mechanical protection function and is commonly used in heavy-duty machinery and detection fields with high requirements. It can withstand large longitudinal tensile forces and also has good magnetic field shielding performance. Copper wire weaving can prevent electromagnetic interference, play a safety protection shielding role in eliminating cable surface potential and induced electricity.
In the production process of cables, another important step is to paint the woven layer for quick identification during construction and operation. In terms of the material of the weaving layer, glass fiber and aramid are commonly used weaving materials for bending resistant drag chain cables. Glass fiber has good thermal stability, with a softening temperature of 700 ℃ and an average thickness of 0.002-0.035 inches. The decomposition temperature of aramid is around 600 ℃, and the average thickness is slightly smaller than that of glass fiber. Fiberglass is easy to color and has a bright and glossy appearance, with its natural white color. Aramid is difficult to make into a bright white color, with only bright colors. Its notable characteristics are wear resistance and shear resistance, and its strength is several times greater than glass fiber, making it a material for many cable outer protective layers.
