The Main Process of Wire and Cable Production

Wire and cable through: drawing, twisting, covering three processes to complete the production, the more complex model specifications, the higher the repeatability.

1. Drawing

In the metal pressure processing, the technical processing method of making the metal forced through the mold (pressing wheel) under the external force, the metal cross-sectional area and obtaining the required cross-sectional shape and size is called metal drawing.

Drawing process points: single wire drawing and drawing system.

2. Twisted

In order to improve the softness of the wire and cable, the overall degree, so that more than two single lines, according to the provisions of the direction of intertwined together known as twisted.

Stranding process points: conductor twisted, into a cable, weaving, steel armor and winding.

3. Covered

According to the different performance requirements of wire and cable, the use of special equipment in the conductor outside the coating of different materials. Coating process points:
A. Squeeze package: rubber, plastic, lead, aluminum and other materials.

B. Longitudinal bag: rubber, wrinkled aluminum material.

C. Wraps: Ribbon tape, mica tape, E-glass fiber belt, non-woven fabrics, plastic tape, linear cotton yarn, silk and other fiber materials.

D. Dip coating: insulating paint, asphalt and so on
