Power cable manufacturing process and the development of special equipment are closely related to each other to promote. New technology requirements, to promote the emergence and development of new special equipment; in turn, the development of new special equipment, but also improve the promotion of new technology promotion and application. Such as drawing, annealing, extrusion line; physical foam production lines and other special equipment to promote the power cable manufacturing process development and improve the cable to improve product quality and production efficiency.

Power cable is through: drawing, twisting, coating three processes to complete, 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 power 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 the power cable, the use of special equipment in the conductor outside the coating of different materials. Coating process points:

(1) squeeze: rubber, plastic, lead, aluminum and other materials.

(2) longitudinal package: rubber, wrinkled aluminum material.

(3) around the bag: tape, mica tape, E-glass fiber belt, non-woven fabrics, plastic belt, linear cotton yarn, silk and other fiber materials.

(4) dip coating: insulating paint, asphalt and so on
