The process of creating an electrical cable
The conductor and insulation are an electrical cable’s two most crucial components. The conductor directs the current through the cable, and the insulator maintains the current’s flow. Other materials may be used to cover cables in order to protect them and increase their lifespan. The conductor is most frequently made of an electrical cable. Other uses for aluminum also exist. The process of making conductors begins with wire drawing. In order to maximize the single wire’s ductility and conductivity while minimizing the skin effect, this requires gradually shrinking the diameter of the wire until it reaches its final diameter.
Getting metal wires suitable for AWG is the first step. On the drawbench, the per or aluminum rod is pulled through a sequence of progressively smaller synthetic diamond dies. This is accomplished via a cooling and lubrication system that prolongs the life of the dies and prevents wire overheating. We exert a great deal of pressure on the metal rod during the drawing process to produce a thinner wire. This makes the wire we receive very brittle and susceptible to fracture when bent. We’ll soften or anneal the completed wire in this phase since it needs to be flexible. The wire is annealed by heating it to the temperature of recrystallization for a predetermined period of time. Preventing the wire from oxidizing is essential.
As was already said, many wires frequently have strands. This is due to the stranded wire’s superior flexibility and electrical performance compared to a single wire for the same cross-sectional area. The wire, which is now pliable and supple, is sent through an extruder where plastic or other insulating material is coated on both sides. Materials are heated till a melt, then poured into the extruder’s rear and forced forward. After exiting the extruder and going through another cooling system, the coated wire is wound onto reels.
The fundamental part of the wire is now prepared. Simply wrapping one or more strands of wire within the protective jacket, together with an interference-preventing layer if necessary, is all that is required for standard electrical and electronic cables. To obtain a higher shaping degree, we commonly employ filler to guarantee that the finished wire is shaped like a circle. Power cables and other cables that must be buried underground now have more safeguards in place. Our conversation for today comes to an end here.
