What is the pitch of the twisting machine?The twisting pitch of the twisting machine refers 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 affects the twisting effect and cable performance.Under different application occasions and stranding requirements,the size of the twist length needs to be selected and adjusted.So,what is the twist length of the twisting machine?HengYi HDMI China Extruder Machine Manufacturer We will introduce the concept and application of the strand length of the twisting machine in detail.

　　1.The concept of twist length

　　Twisting distance is a parameter in the twisting process of the twisting machine.It refers to the number of turns of the same cable or wire twisted in a twisted length of 1 meter.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 reliability and performance of the cable.

　　2.Application of lay length

　　For the selection of twist length,it is necessary to make a decision according to the actual situation and product requirements.When the twisting distance is too small,the twisting machine is 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 larger,and it is susceptible to external interference and damage.Therefore,for different cable types and uses,the appropriate twist length should be selected according to the needs.

　　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.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.

　　3.The influence of twist length

　　The size of the lay distance has a certain influence on the physical properties,service life and electrical performance of the stranded wire.Generally speaking,when the lay length is too large,the mechanical strength and bending performance of the cable will become unstable,which may cause the cable to be easily broken or damaged during use.In addition,if the twist distance is too large,the mutual inductance loss between the cables will increase,which will make the impedance of the wire change more significantly.

　　On the contrary,when the lay length is too small,the mutual inductance between the cables will increase,which will lead to the deterioration of the electrical performance of the cable,such as voltage loss and mutual inductance interference.However,in some special cases,such as applications with high radio frequency,appropriately smaller lay lengths will help reduce wire inductance and reduce the influence of mutual inductance interference.

　　To sum up,the twist length needs to be selected and adjusted according to the specific type and application of the cable.Practice has shown that choosing an appropriate lay length can effectively improve the quality of the cable and prolong the service life of the cable.
