Structural form of twisted pair braided wire and requirements of its braiding equipment
At present, most twisted pair braids used are mainly composed of three parts. From the outside to the inside, they are sheath layer, insulating layer and conductive inner core. Its conductive inner core is used to transmit current, so copper inner core and aluminum inner core with high conductivity are selected, which can effectively reduce power loss and voltage.
For the twisted pair braided wire, the function of the insulating layer is to prevent the radial leakage of current and ensure the use safety. Therefore, the insulating layer of the twisted pair braided wire should have good insulation performance and heat resistance, as well as certain strength. The braid is only one of many sheath layers or outer sheath layers. The braid will also have different functions according to the different materials used and different parts in the structure.
At present, the twisted pair braid has two common structures. One is the fiber braid, which is a light protective layer. It is mainly to protect the twisted pair braid, reduce the erosion of various light, temperature and humidity and the damage of external forces, and protect the twisted pair braid from safe and normal use.
The other is the metal braid, which is divided into copper wire braid and steel wire braid. The main feature of copper wire braid is that it can effectively protect against electromagnetic interference, remove the shielding effect of the surface potential of twisted pair braid, and remove induced electricity. In addition, it also has the function of safety protection, and can feed back the leakage in time. The main feature of steel wire braid is good mechanical protection, can withstand large tensile force, can shield magnetic field, and can be used more safely.
In order to ensure the quality of twisted pair braided wire, the process requirements of braiding machine are very strict. For example, its control device should be sensitive and easy to adjust; It is required that the disconnection rate is low, the disconnection or wireless shall be able to stop automatically, and the production action shall be sensitive and smooth. As the traction device of knitting machine, the spindle must be stable without collision; In addition, the weaving pitch shall be stable, the wire strands shall be arranged evenly, and the weaving density shall be uniform.
