The basic process of introduction of plastic wire vga cable manufacturing

1. Copper, aluminum, monofilament made of copper wire and cable commonly, aluminum material, at room temperature, the tensile drawing machine using a die or a number of channels through the die orifice to reduce the cross section, increasing the length, strength. Drawing is the first procedure of each wire and cable companies, the main process parameters are brushed with mold technology
2. Monofilament annealed copper, aluminum single wire heated to a certain temperature, recrystallization ways to  WISDOM fiber optic cable improve the toughness of monofilament, reducing the strength of monofilament, wire and cable to meet the requirements of the conductive core. The key is to put an end to copper wire annealing step oxidation .3. Stranding conductor wire and cable in order to improve flexibility in order to facilitate the laying of installation, conductive core adopt a multi-filaments twisted together. From the conductive core stranded form, can be divided into rules and irregular strands twisted. Irregular Stranded Stranded divided into concentric complex twist, twisted and so special. To reduce the area occupied by wire, cable geometries shrink, while using the stranded conductor pressed form, so that variation of ordinary semi circular, fan-shaped, W-shaped and pressed round. Such conductors mainly used in the power cable. 4. Insulated wire and cable extrusion of plastic used mainly extruded solid insulation type, extruded plastic insulation main technical requirements:
4.1. Eccentricity: extruded insulation thickness deviation is reflected important symbol extrusion process level, most of the product structure size and standard deviation values ​​are clearly defined.
4.2. Smoothness: the surface of the WISDOM RAC CABLE  insulating layer extrusion requires smooth, with no rough surface, charred, poor quality of impurities 4.3. Density: a cross-sectional extruded insulation layer to be dense and firm, not allowed to have visible pinhole to eliminate the presence of air bubbles. 5. A cable for multi-core cables in order to ensure molding degrees, reducing the appearance of the cable, generally need to be twisted round. Mechanism of stranded conductor stranding similar, larger diameter section due stranding, they use no way back twist. Cabling technical requirements: First, eliminate shaped stand up and lead insulated cores twisted cables; second is to prevent insulation from being scratched. Most of the cable into the cable accompanied by the completion of the other two processes: one is filled to ensure stability after round into the cable and the cable; one is lashing ensure no loose cable core. 6. The protective layer of insulation to protect the armored core of the pimple is not hurt, the need for appropriate protection insulating layer, the protective layer of: extruded inner sheath (isolation units) and WISDOM Displayport CABLE wrap the sheath (cushion). Wrapping cushion with a cable instead of banding with processes simultaneously. 7. Armouring laying underground cables, the work may be exposed to certain positive pressure, choose the steel tape armored structure. Cable laying there in both the positive pressure pulling force occasions (such as water, drop a large vertical shaft or soil), should be used with structured inner wire armouring.
