Damaged and Prevented Methods of Shielded Cables

There are many correct or incorrect processes in the manufacture of the shield. One of the important parameters is the braiding angle of the shield.
In the cable used for the drag chain, the load on the cable outer diameter shield must be taken into account. An unreasonable shield braiding angle will further increase the tensile load and cause damage to the shield. As a result, the shielding effect is reduced, and even a short circuit may occur when the sharp cable tail pierces the wool fabric or the foil gold material contacts the core wire. A useful tip for everyone: If the insulation is stripped, the shield can easily be pushed back into the sheath, but such a shield cannot be applied to energy supply systems, moving highly flexible cables .
The braiding angle of the shield, which is determined by long-term experiments, can effectively offset the tension and is therefore very suitable for the drag chain. The shield does not relax due to the stable inner sheath. In a twisted wire structure, the shield itself has torsional resistance.
Sheath worn or damaged
Any internal structural defects are difficult to detect from the outside, but the problem of the sheath can be directly observed by the naked eye. The sheath is the first layer of protection for the precise internal structure of the cable. This is why cracked, worn, and deformed sheaths are very serious quality problems. To avoid this problem,
Hammer extrusion jacket
Manufacturing processes and materials are also important factors in determining product quality. In some so-called cables suitable for drag chains, the sheath is usually of a tubular type and therefore cannot provide the necessary support of the strand structure during the long-term bending process, so that the strand structure can be easily split.
As a manufacturer of the drag chain system, igus has developed an armored extrusion jacket.
This sheath ensures that the core does not loosen when the cable is in motion. The reason is that the sheath is extruded with a particularly large pressure. It acts like a guide groove, guiding the movement of the core wire and also supporting it. It is therefore very suitable for drag chains.
