核心提示:任何内部結構的缺陷都很難從外部察覺,但護套的問題肉眼可以直接觀察到。護套是電纜精密内部結構的第一層保護。這就是為什麼破裂、磨損和膨脹變形的護套是非常嚴重的質量問題。為了避免這樣的問題,易格斯提供了七種不同材料的電纜護套,供用戶根據其機械的相應工作環境進行選擇。
在屏蔽層的制造過程中,有許多的正确或不正确的工藝。其中很重要的一個參數就是屏蔽層的編織角度。
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.

在用于拖鍊的電纜中,電纜外徑的屏蔽層所承受的負載必須被考慮進去。不合理的屏蔽層編織角度會進一步增加張力負載,導緻屏蔽層的破損。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.由此會造成屏蔽效果減弱,當鋒利的電纜尾部戳穿羊毛織物或箔金材料接觸到芯線時,甚至會造成短路。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,我們推薦您一個有用的小訣竅:如果将絕緣層剝去,就能夠很容易地将屏蔽層推回到護套内,但這樣的屏蔽層無法适用于能源供應系統中,運動着的高柔性電纜。當然,電纜回收公司能夠提供這些問題的直接解決方案: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:


通過長期的實驗所決定的屏蔽層編織角度能夠有效地抵消張力,因而非常适用于拖鍊。

The braiding angle of shield layer determined by long-term experiments can effectively counteract the tension, so it is very suitable for towing chain.
由于穩定的内護套,屏蔽層不會松弛失效。

Because of the stable inner sheath, the shielding layer will not relax and fail.
在絞線結構中,屏蔽層本身就具有抗扭轉性能。
In the stranded structure, the shielding layer itself has torsion resistance.

護套磨損或破損
Wear or breakage of sheath

任何内部結構的缺陷都很難從外部察覺,但護套的問題肉眼可以直接觀察到。護套是電纜精密内部結構的第一層保護。這就是為什麼破裂、磨損和膨脹變形的護套是非常嚴重的質量問題。為了避免這樣的問題,易格斯提供了七種不同材料的電纜護套,供用戶根據其機械的相應工作環境進行選擇。
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.

甲胄式擠壓成型護套

Armour extrusion sheath
制造工藝和材料同樣是決定産品質量的重要因素。在一些所謂的适用于拖鍊的電纜中,護套通常成管狀型,因此無法在長期的彎曲過程中,提供絞線結構必要的支持,從而使絞線結構易于分裂。

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.
易格斯作為拖鍊系統的首家制造商,因此而研發了一種甲胄式擠壓成型護套。

As the first manufacturer of tow chain system, Igus developed an armour extrusion sheath.
這種護套可确保電纜在運動時,其芯線不會松開。原因是該護套是通過特别大的壓力擠壓而成,它就像是一個導向槽,對芯線的運動起到了導向作用,同時還起到了支撐作用。因而非常适用于拖鍊。

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.
總結一下适用于拖鍊的高柔性電纜的質量保證: 中心去應力設計; 多束成纜結構; 屏蔽電纜中采用甲胄式擠壓成型的内護套; 全屏蔽絕緣編織網; 優化的屏蔽編織角度; 甲胄式擠壓成型的護套。
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.
