The manufacture of ELectric Wire & Cable is completely different from that of most electromechanical products. Electromechanical products are usually used to be assembled into parts, multiple parts and then assembled into a single product, the number of products or the number of pieces measured. The ELectric Wire & Cable are based on the length of the unit of measurement. All ELectric Wire & Cable are from the beginning of the conductor processing, in the periphery of the conductor layer by layer with insulation, shielding, into a cable, sheath, etc. made of ELectric Wire & Cable products. The more complex the product structure, the more the level of stacking.
ELectric Wire & Cable through: drawing, twisting, covering three processes to complete the production, the more complex model specifications, the higher the repeatability.
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.
In order to improve the softness of the ELectric Wire & 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.
According to the different performance requirements of ELectric Wire & 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
