wire and cableIt is produced through three processes: drawing, twisting, and wrapping. The more complex the model specifications, the higher the repeatability.

1. Drawing

In metal pressure processing The technical processing method of forcibly passing metal through a mold (pressure wheel) under external force, compressing the cross-sectional area of the metal, and obtaining the required cross-sectional area shape and size is called metal drawing.

The drawing process is divided into single wire drawing and twisting drawing.

2. Twisting

In order to improve the flexibility and integrity of wires and cables, twisting two or more single wires together in the specified direction is called twisting.

The twisting process includes conductor twisting, cabling, weaving, steel wire armor, and winding.

3. Covering

According to different performance requirements for wires and cables, the equipment used is wrapped with different materials on the outside of the conductor.

The wrapping process is divided into:

A. Squeezing: Materials such as rubber, plastic, lead, aluminum, etc.

B. Vertical package: rubber, wrinkled aluminum strip material.

C. Wrapping: Ribbon paper tape, mica tape, alkali free glass fiber tape, non-woven fabric, plastic tape, etc., linear fiber materials such as cotton yarn and silk.
