A conductor is a material in which electricity can flow through. Electrical conductors are made up of metals such as, copper, aluminum, etc. These metals are used to make wires. Most wires are made out of copper because it conducts electricity with high flexibility and very little resistance.
The first stage in the manufacturing process of a conductor is the wire-drawing. The wire-drawing consists of reducing the diameter of the wire gradually to fit its final diameter to increase ductility and conductivity.
Once the diameter is reduced, the wire is drawn further to decrease the diameter of the wire to the size needed for each kind of conductor.
In the second stage of this process, the wires undergo a heat treatment called annealing. Annealing is a process of heating metal and allowing it to cool slowly in order to remove internal stresses and toughen the metal. The point of this treatment is to increase the conductivity of the wire.
Now we need insulation. Insulators are different synthetic materials that are used to insulate electrical wires. Because the current runs along the outside of the copper wires, they need to be insulated from other wires and conductive surfaces. An insulating cover over the conductor also prevents any current leakages.
Different insulation materials may be used depending on the characteristics of the cable required. Quality of an insulation material depends on two basic characteristics: insulation capacity and its heat resistance.
Cables sometimes contain several different wires wrapped together in an insulator. In some cases, the cable may require additional elements in order to improve protection. For instance, electrical coverings called “screens” insulate the signals that circulate in the cable, shielding the power cables to prevent them from external interference.

Main Causes of Failure
1) Natural Damage
The wiring harness has exceeded the service life, which causes the wires to age, the insulation layer to rupture, and the mechanical strength to decrease significantly, which causes short circuits, disconnections, grounding, etc. to causes the wire harnesses to burn out. Wiring harness terminals are oxidized and deformed, resulting in poor contact, which can cause electrical equipment to malfunction.
2) Damage to the wiring harness due to malfunction of the electrical equipment
When electrical equipment is overloaded, short-circuited, grounded may cause damage to the wiring harness.
3) Human Fault
When assembling or overhauling automobile parts, metal objects crush the wire harness and break the insulation of the wire harness; the position of the wire harness is incorrect; The lead position of the electrical equipment is incorrectly connected; The battery's positive and negative leads are connected reversely; when the maintenance circuit is faulty, random connection, random wiring harness wiring, then cause abnormal operation of electrical equipment, and even burn the wiring harness.
