The main cable technology

- Nov 10, 2017-

cable is drawn, stranding, coating three kinds of technology to make the finished, the more complex model specifications, the higher the repeatability.

1. Drawing: In metal pressure machining, the metal is forcibly passed through a die (pinch) under the action of an external force, the metal cross-sectional area is compressed, and the desired cross-sectional shape and size of the technical processing method is called metal Draw. Drawing process points: single-wire drawing and stranding drawing.                                                                                                                                                2. Stranding: In order to improve the softness of the cable, the overall degree, so that more than 2 single lines, according to the specified direction intertwined as twisted. Winding process points: conductor stranded, into a cable, braid, wire armor and wound.                                                                                                                       3. Cover: According to the different performance requirements of the cable, the use of special equipment in the conductor coated with different materials. Coating process points: A. Extrusion package: rubber, plastic, lead, aluminum and other materials. B. longitudinal package: eraser, wrinkled aluminum strip material. C. Around the package: Ribbon tape, mica tape, E-glass fiber tape, non-woven fabrics, plastic belts, etc., linear cotton yarn, silk and other fiber materials. D. dip coating: insulating paint, asphalt and so on.                                                                                                                                                                                                                   Belltronic is professional galvanized steel tape manufacturer, our products are in promotion.
