[China Wire & cable network]
In the process of manufacturing the shield, there are many correct or incorrect processes. One of the most important parameters is the braiding angle of the shielding layer
The cable is used for the towline, the shielding layer of cable diameter under load must be taken into consideration. The shielding layer unreasonable braiding angle will further increase the tension load, resulting in damage of the shielding layer. This will cause the shielding effect is weakened, while the sharp tail sheep wool fabric through cable or gold foil material contact to the core when the line, even cause a short circuit. Here, we recommend a useful trick: if the insulation off, can easily be pushed back to the shielding layer in the sheath, but this shielding layer is not suitable for the energy supply systems, high flexible cable movement. Of course, Igs can provide the direct solution to these problems:
The shielding layer through long-term experiment determined the braided angle can effectively offset the tension, so it is suitable to the chain.
Because of the stable inner sheath, the shielding layer will not relax and fail
In the twisted wire structure, the shielding layer itself has anti torsion performance
Sheath wear or breakage
Any defect in the internal structure is very difficult to detect from the outside, but the sheath problem can be directly observed. The naked eye is the first layer of protective sheath cable precision internal structure. This is why sheath rupture, wear and expansion deformation quality problem is very serious. In order to avoid this kind of problem, Igs offers seven cable the sheath of different materials, for the user to choose according to their corresponding mechanical working environment.
A type extrusion molding sheath
The manufacturing process and materials is also an important factor in determining the quality of the products. In some of the so-called in the application of cable drag chain, usually tubular sheath type, so it is difficult to bend the long process and provide the necessary support strand structure, so that the wire structure is easy to split.
Igs as the first manufacturer of towline system, thus developed an armor type extrusion sheath.
This can ensure that the cable sheath in the movement, the wire will not loosen. The reason is that the sheath is through special high pressure extrusion, it is like a guide groove of the core wire movement has played a leading role, but also played a supporting role. It is very suitable for the chain.
High quality flexible cable to summarize that applies to the towline center to stress design; multi beam cable structure; the inner sheath armor type extrusion shielded cables; shielded insulation braid; optimized shielding angle; sheath armor type extrusion molding
