What effect does excessive current have on a conductor's insulating cover?

Excessive current flowing through a conductor generates heat due to the resistance offered by the wire. When the current exceeds the conductor's rated capacity, the heat produced can reach levels high enough to compromise the insulating cover surrounding the conductor. The insulating material is typically designed to withstand a certain amount of heat, but if this threshold is surpassed, the insulation can start to degrade. One of the most critical failures of this insulation is that it can melt or even catch fire under extreme current conditions. This is especially true for plastics and rubber, which are common insulating materials. As the insulating cover melts or burns, it can lose its protective function, exposing the conductor and increasing the risk of electrical shock, short circuits, and fires. Therefore, the high temperature caused by excessive current directly leads to the degradation of the insulating material, resulting in potentially hazardous situations.
