На што трэба звярнуць увагу пры папярэднім награванні правадоў і правадоў кабеляў?

---

Провад і кабель выкарыстоўваюцца для перадачы эл (магнітныя) энергіі. Інфармацыя і рэалізацыя электрамагнітнага пераўтварэння энергіі драцяных вырабаў. Шырока кажучы, провад і кабель таксама называюць кабелем, і вузка кажучы, кабель адносіцца да ізаляванага кабеля. Яго можна вызначыць як сукупнасць наступных частак: адна або некалькі ізаляваных правадных жыл, і яны могуць мець сваю ашалёўку, агульны ахоўны пласт, і вонкавая абалонка, кабель таксама можа мець дадатковыя правадыры без ізаляцыі.

We are also aware that wire and cable are everywhere in our lives. Wire and cable in the production process, we often encounter conductors that need to preheat, but the conductor preheating reasons and process parameters are not enough to understand the setting. Так, the following ZMS wire and cable factories are to introduce you to the preheating of wire and cable conductors considerations.

Першы, for the elimination of moisture to preheat, please try to use dry filling fiber material.

Другі, under the premise of ensuring the stability of the wire release, let the preheater and the head be as close as possible to avoid heat dissipation. For UL wire, the tensile strength of the insulation is required, and the physical and mechanical properties test is arranged during the first inspection.

Трэці, when the conductor surface moisture is more serious, should be wiped before entering the preheater to avoid conductor oxidation and produce spots.

Чацвёрты, induction preheating is only for bare conductors, not for insulated cores. When the cable is extruded outside they need to have a certain adhesion requirement, the adhesion of the insulation should be slightly greater than the adhesion of the outside. The preheating temperature is set to assess the adhesion force as a guideline.

Пяты, the preheating temperature is too high, which will cause the filling fiber shrinkage or even carbonization, resulting in lower tensile strength, please pay attention to check. In production debugging, wire break processing, and other abnormal processing, should pay attention to the change of preheating temperature, if necessary, the need to temporarily close the preheater.

The above is the wire and cable conductor preheating need to pay attention to some issues, you all understand? I hope it will be helpful to you. If you want to know more information about the cable, pay attention to ZMS Cable Co.
