Damaged and preventive method of controlled shielded cable

Damaged and preventive method of controlled shielded cable
There are many correct or incorrect processes in the manufacture of the shield. One of the most important parameters is the braiding angle of the shield.

In the cable used for the towline, the load on the shield of the outer diameter of the cable must be taken into account. An unreasonable braiding angle of the shield further increases the tensile load, resulting in damage to the shield. As a result, the shielding effect is weakened, and even a short circuit is caused when the sharp controlled shielded cable tail is pierced by the wool fabric or the foil gold material contacts the core wire. Here, we recommend a useful little trick: if the insulation is stripped, the shield can be easily pushed back into the jacket, but such a shield can not be used in the energy supply system, moving Highly flexible cable. Of course, Ray Antenna can provide a direct solution to these problems:

controlled shielded cable

Through long-term experiments, the shield braiding angle of the controlled shielded cable can effectively offset the tension, which is very suitable for the towline.

Due to the stable inner sheath, the shield does not relax.

In the stranded structure, the shield itself has anti-twist properties.

Sheath wear or breakage

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 jacket is the first layer of protection for the precise internal structure of the cable. This is why rupture, wear and expansion deformation of the jacket is a very serious quality problem. In order to avoid such problems, igus offers cable jackets of seven different materials for the user to choose according to the corresponding working environment of the machine.

Armored extruded jacket

Manufacturing processes and materials are also important factors in determining product quality. In some so-called cables suitable for towline, the sheath is generally tubular in shape and therefore does not provide the necessary support for the stranded structure during long-term bending, thereby making the strand structure susceptible to splitting.

As the first manufacturer of the towline system, igus has developed a nail-shaped extruded jacket.

This jacket ensures that the core does not loosen when the cable is moving. The reason is that the sheath is extruded by a particularly large pressure, which acts as a guiding groove, which guides the movement of the core wire and also serves as a support. It is therefore very suitable for drag chains.

Summarize the quality assurance of high-flexible cables suitable for towline: central stress-relieving design; multi-bundle cable-forming structure; armor-type extruded inner sheath in controlled shielded cable; fully shielded insulated woven mesh; optimized shield braiding Angle; armored extruded jacket.
