In overhead transmission lines suspended by towers and in this type of situation the bare stranded conductor on the transmission line is generally made out by using Aluminium materials. There are various types of conductors which are used in transmission line. The following are the commonly conductors use for overhead transmission lines. 1. All Aluminium Conductor (AAC) 2. All Aluminium Alloy Conductor (AAAC) 3. Aluminium Conductor Steel Reinforced (ACSR) 4. Aluminium Conductor Alumin...

The “shielding” on the cable structure is essentially a measure to improve the electric field distribution. The cable conductor is made up of multiple wires twisted, and it is easy to form an air gap between it and the insulating layer. The surface of the conductor is not smooth, which will cause the electric field to concentrate. Add a layer of shielding layer of semi-conductive material on the surface of the conductor, which has the same potential as the shielded conductor and i...

power cable manufacturing process 1. Copper or aluminum rod drawing Process Commonly used copper and aluminum rods for wires and cables, at room temperature, use a wire drawing machine to pass through one or several die holes of the drawing die to reduce the cross section, increase the length and improve the strength. Wire drawing is the first process of each wire and cable company, and the main process parameter of wire drawing is mold matching technology. The drawing process has ...
