Qu’est - ce que la Pitch de la machine twisting? The twisting Pitch of the Twisting Machine references to the distance required for any one wire in the Twisted bundle to be Twisted for one week when the cable or Wire is Twisted. The twisting length of the Twisting Machine is an important parameter that effects the twisting Effect and Cable Performance (la longueur twisting de la machine twisting est un paramètre important qui affecte l'effet twisting et la performance du câble). Under Different Application occasions and stranding Requirements, the size of the twist length needs to be selected and adjusted (la taille de la longueur minimale nécessaire pour être sélectionnée et adjusted). Qu'est - ce qui est la longueur twist de la machine twisting? Hengyi HDMI China Extruder Machine Manufacturer we will introduce the Concept and Application of the Strand length of the Twisting Machine in detail (nous introduirons le concept et l'application de la longueur d'onde de la machine twisting dans le détail).

Le concept de la longueur twist

La distance twisting est un paramètre dans le processus twisting de la machine twisting. It refers to the number of turns of the same cable or Wire Twisted in A Twisted length of 1 Meter (il fait référence au nombre de tours du sable ou sans fil dans une longueur Twisted de 1 mètre). The size of the lay length is related to factors such as the number of Twisted wires, the lateral Position of the wires, the twisting direction, and the Characteristics of the Wire material. For Some Special Twisted cables or wires, the Adjustment of lay length will also have a certain Relationship with the Relativity and Performance of the Cable (pour certains Câbles spéciaux ou sans fil, l'Adjustment de la longueur du droit aura une relation certifiée avec la relativité et la performance du câble).

Application de lay length

For the Selection of Twist length, it’s necessary to make a decision according to the actual Situation and product requirements (pour la sélection de la longueur minimale, il est nécessaire de créer une décision d’accord sur la situation actuelle et les exigences du produit). Quand la distance de twisting est petite, la machine de twisting est prone to Problems such as loosening or winding when twisting the wires, resulting in damage to the Cable and shortened service life. When the lay length is too large, the distance between the cables becomes large, and it’s susceptible to external Interference and Damage (quand la longueur de la loi est trop large, la distance entre les capsules est plus large, et il est susceptible à l’interface externe et au barrage). Therefore, for Different Cable types and uses, the approved Twist length should be selected according to the Needs (therefore, pour différencier les types de câbles et les utilisations, l'approbation de la longueur minimale doit être sélectionnée pour les besoins).

The Optimal design can be adopted First, and then the Theoretical Value of the twist length can be calculated. In the actual twisting process, the twist length can be adjusted according to the actual situation (en anglais seulement) If the twisting Distance is too large or too small, it is necessary to adjust the Parameters of the Twisting Machine in time to ensure the Quality and Service Life of the Cable (si la distance twisting est trop grande ou trop petite, c'est nécessaire pour ajouter les paramètres de la machine twisting dans le temps pour ensure la qualité et le Service de la vie du câble).

L'influence de la longueur twist

The size of the lay distance has a Certified Influence on the Physical Properties, Service Life and Electrical performance of the Stranded Wire (la taille de la distance de la loi a une influence certifiée sur les propriétés physiques, la vie de service et la performance électrique de la Stranded Wire). Generally speaking, when the lay length is too large, the Mechanical Strength and bending Performance of the Cable will come Unstable, who may cause the Cable to be easy Broken or damaged during use (en anglais seulement). In addition, if the twist Distance is too large, the Mutual Industry Loss between the cables will increase, who will make the impédance of the Wire change more signally (en anglais seulement)

On the contrary, when the lay length is too small, the Mutual Industry between the cables will increase, which will lead to the Deterioration of the Electrical performance of the Cable, such as voltage loss and Mutual Industry Interference (en anglais seulement). However, in some special cases, such as applications with High Radio Frequency, appropriately smaller lay Lengths will help reduce Wire Industry and reduce the Influence of mutual Industry Interference.

To sum up, the twist length needs to be selected and adjusted according to the specific type and Application of the Cable (en anglais seulement). Practice has shown that Choosing an appropriate lay length can effective Improve the Quality of the Cable and prolong the Service Life of the Cable (la qualité du cable et la prolong de la vie de service du cable).
