The main principle of the twisted wire is: when the copper wire passes through the twisted bow on the twisted machine, the twisted bow passes through the circular motion, so that the individual copper wires are helically wound together; the twisted copper wire is a single copper wire Where the maximum amount is used, copper wires of different specifications and different numbers are twisted together in a certain order and lay length to become a conductor with a larger diameter. The silk is much softer and the resulting wire has better bending properties.


Twisting machine twist definition

The single wire appears once at a fixed distance along the direction of the twisted wire, and the fixed distance apart is the pitch of the twisted wire (referred to as the twist pitch). Another definition of twist pitch is: refers to the vertical distance that the twisted wire moves forward after every 360 degrees of rotation along the twisting axis, the unit is mm, and the English is pitch.

Tows are twisted from multiple single wires. Generally speaking, the single wires of the bundle are many and thin, which increases the flexibility of the wire and cable, and also improves the reliability of the line connection. In order to have better flexibility or high reliability, the conductors of some wires and cables are twisted.


In order to bundle or twist the single wires with a certain helix angle (or pitch), the equipment must meet the following requirements: one is to make all the single wires rotate around the central axis of the equipment; the other is to make the twisted products in a straight line Forward movement. By changing the coordination of these two movements, the size of the helix angle can be adjusted, so that the produced stranded wire or bundled wire meets the structural requirements.


The stranding machine is composed of main parts such as pay-off, traction, wire arrangement and take-up, drag and transmission system and control system. In addition, there are also devices such as a branch board, a parallel die (also known as a press die), and a meter counter.
