The main process steps of wire and cable manufacturing

The main process steps of wire and cable manufacturing
Wire and cable is adopted: drawing, stranding, covering three process to produce complete, specifications and more complex, higher repeatability.
1 Drawing
In metal pressure processing. The metal is forced through a die under the action of external force (roller), metal cross sectional area is compressed, technical process and obtain the required shape and size of the cross-sectional area called the metal drawing.
Drawing process: wire drawing and stranding drawing.
2 stranding
In order to improve the flexibility of wire and cable, the overall degree, make the line more than 2, according to a prescribed direction interwoven together called stranding.
Stranding process: conductor stranding, cabling, weaving, and winding steel wire armoring.
The 3 coating
According to the different performance requirements of wire and cable, using special equipment for coating materials with different conductor outside. Coating process:
A. extruded: rubber, plastic, lead, aluminum and other materials.
B. is longitudinally covered: rubber, corrugated aluminium strip material.
Wrapped around the C.: ribbon tape, tape, alkali free glass fiber tape, non-woven fabrics, plastic belt, cotton yarn, yarn linear fiber materials.
D. dipping: insulating paint, asphalt etc.
