Shielded cable damage and prevention methods
There are many correct or incorrect processes involved in the fabrication of the shield. One of the most important parameters is the shielding Angle.In cables used for towing chains, the load on the shielding layer of the cable's outer diameter must be taken into account. Unreasonable shield weaving Angle will further increase the tension load, leading to the damage of the shield. This can make shielding less effective and can even cause a short circuit when the sharp end of the cable punctured wool or chaff and touched the core. Here, we recommend a useful tip: if you strip the insulation, you can easily push the shield back into the sheath, but such a shield will not be suitable for the highly flexible cables moving in the energy supply system. Of course, Egus can provide a direct solution to these problems:
The shielding Angle determined by long-term experiments can effectively counteract the tension, so it is very suitable for towing chains.
Due to the stable inner sheath, the shield will not relax and fail.
In the twisted wire structure, the shield itself has torsional resistance.
Sheath worn or damaged
Any defects in the internal structure are hard to detect from the outside, but problems with the sheathing are directly visible to the naked eye. The sheath is the y.i layer of protection for the precise internal structure of the cable. This is why cracked, worn and inflated sheathing is a very serious quality problem. To avoid this problem, Egus offers seven different materials of cable sheathing, which users can choose according to the corresponding working environment of their machinery.
Armor type extruded sheath
Manufacturing process and materials are also important factors in determining product quality. In some so-called cable for tow chains, the sheathing is usually tubular and therefore does not provide the necessary support for the strand structure during the long bending process, so that the strand structure is prone to splitting.
This sheath ensures that the core of the cable will not loosen when it is in motion. The reason is that the jacket is extruded with extra pressure. It acts as a guide groove, guiding the movement of the core, and also acting as a support. Thus very suitable for towing chains.
To summarize the quality assurance of high flexible cable suitable for towing chain: center stress relief design; Multi-beam cable structure; The shield cable adopts the inner sheath of the armour type extrusion molding; Fully shielded insulated braided net; Optimized shielding braiding Angle; Armor type extruded sheath.
