Sitong cable "quality first, customer supreme principle” invite you to pay attention to today's new information:

二、Main process of wire and cable

Wire and cable are made by three processes: drawing, twisting and coating. The more complex the model specifications, the higher the repeatability.

1. Drawing

 In metal press working, a technical processing method in which a metal is forced to pass through a mold (pressure wheel) under an external force, a metal cross-sectional area is compressed, and a desired cross-sectional area shape and size is obtained is called metal drawing.

Drawing process: single wire drawing and strand drawing.

2. Twist

In order to improve the softness and integrity of the wire and cable, it is called twisting by interlacing two or more single wires in a predetermined direction.

Twisting process: conductor stranding, cabling, weaving, wire mounting and winding.

3. Coated

Depending on the performance requirements of the wire and cable, special equipment is used to coat different materials on the outside of the conductor. Coating process points:

A. Extrusion: rubber, plastic, lead, aluminum and other materials.

B. Vertical package: rubber, corrugated aluminum strip material

C. Wrap: tape-like paper tape, mica tape, alkali-free glass fiber tape, non-woven fabric, plastic tape, etc., linear cotton yarn, silk and other fiber materials.

D. Dip coating: insulating paint, asphalt, etc.
