核心提示:任何内部结构的缺陷都很难从外部察觉,但护套的问题肉眼可以直接观察到。护套是电缆精密内部结构的第一层保护。这就是为什么破裂、磨损和膨胀变形的护套是非常严重的质量问题。为了避免这样的问题,易格斯提供了七种不同材料的电缆护套,供用户根据其机械的相应工作环境进行选择。
在屏蔽层的制造过程中,有许多的正确或不正确的工艺。其中很重要的一个参数就是屏蔽层的编织角度。
In the manufacturing process of shielding layer, there are many correct or incorrect processes. One of the most important parameters is the braiding angle of the shield layer.

在用于拖链的电缆中,电缆外径的屏蔽层所承受的负载必须被考虑进去。不合理的屏蔽层编织角度会进一步增加张力负载,导致屏蔽层的破损。In tow cable, the load on the shield layer of cable outer diameter must be taken into account. The unreasonable braiding angle of shield layer will further increase the tension load, leading to the damage of shield layer.由此会造成屏蔽效果减弱,当锋利的电缆尾部戳穿羊毛织物或箔金材料接触到芯线时,甚至会造成短路。As a result, the shielding effect will be weakened. When the sharp cable tail pierces wool fabric or foil material touches the core wire, it will even cause short circuit.在此,我们推荐您一个有用的小诀窍:如果将绝缘层剥去,就能够很容易地将屏蔽层推回到护套内,但这样的屏蔽层无法适用于能源供应系统中,运动着的高柔性电缆。当然,电缆回收公司能够提供这些问题的直接解决方案:Here, we recommend a useful trick: if you strip the insulation, you can easily push the shield back into the sheath, but such shield can not be applied to high flexible cables moving in the energy supply system. Of course, cable recycling companies can provide direct solutions to these problems:


通过长期的实验所决定的屏蔽层编织角度能够有效地抵消张力,因而非常适用于拖链。

The braiding angle of shield layer determined by long-term experiments can effectively counteract the tension, so it is very suitable for towing chain.
由于稳定的内护套,屏蔽层不会松弛失效。

Because of the stable inner sheath, the shielding layer will not relax and fail.
在绞线结构中,屏蔽层本身就具有抗扭转性能。
In the stranded structure, the shielding layer itself has torsion resistance.

护套磨损或破损
Wear or breakage of sheath

任何内部结构的缺陷都很难从外部察觉,但护套的问题肉眼可以直接观察到。护套是电缆精密内部结构的第一层保护。这就是为什么破裂、磨损和膨胀变形的护套是非常严重的质量问题。为了避免这样的问题,易格斯提供了七种不同材料的电缆护套,供用户根据其机械的相应工作环境进行选择。
Any internal structural defect is difficult to detect from the outside, but the problem of the sheath can be directly observed by the naked eye. Sheath is the first layer of protection for the precise internal structure of cable. That's why sheaths with rupture, wear and expansion deformation are very serious quality problems. To avoid this problem, Eagles provides seven different cable sheaths for users to choose according to the corresponding working environment of their machines.

甲胄式挤压成型护套

Armour extrusion sheath
制造工艺和材料同样是决定产品质量的重要因素。在一些所谓的适用于拖链的电缆中,护套通常成管状型,因此无法在长期的弯曲过程中,提供绞线结构必要的支持,从而使绞线结构易于分裂。

Manufacturing technology and materials are also important factors to determine product quality. In some so-called towed cables, the sheath is usually tubular, so it can not provide necessary support for the stranded structure in the long-term bending process, thus making the stranded structure easy to split.
易格斯作为拖链系统的首家制造商,因此而研发了一种甲胄式挤压成型护套。

As the first manufacturer of tow chain system, Igus developed an armour extrusion sheath.
这种护套可确保电缆在运动时,其芯线不会松开。原因是该护套是通过特别大的压力挤压而成,它就像是一个导向槽,对芯线的运动起到了导向作用,同时还起到了支撑作用。因而非常适用于拖链。

The sheath ensures that the core of the cable does not loosen when it is in motion. The reason is that the sheath is extruded by a very large pressure. It is like a guide groove, which plays a guiding role in the movement of the core wire and also plays a supporting role. So it is very suitable for towing chain.
总结一下适用于拖链的高柔性电缆的质量保证: 中心去应力设计; 多束成缆结构; 屏蔽电缆中采用甲胄式挤压成型的内护套; 全屏蔽绝缘编织网; 优化的屏蔽编织角度; 甲胄式挤压成型的护套。
Summarize the quality assurance of high flexible cables suitable for tow chains: center de-stress design; multi-bundle cable-forming structure; inner sheath formed by armour extrusion in shielded cables; fully shielded insulated braided mesh; optimized shielding braiding angle; armour extrusion sheath.
