Construction. The construction of an extension cord is simple. A plastic covering is on the outside, visible part of the cord. This shield is intended to protect the inside of the cable from damage and the weather, while helping to insulate the wire. Below this layer is the insulation, which is normally made of thick, special plastic.

How does electricity produce heat?
Heat Production. Electricity produces warmth when it is conducted through a material. The insulation layer on the wire helps to keep this heat in, which makes the cable more efficient and helps keep it from heating up and damaging the objects around it (or causing a fire).
Is it safe to use a 3 pin extension cord?
Most extension cords use a three-pronged connection. This connection is safer than a two-pronged connection because it contains a third pin that acts as a grounding connector. This means that the cable is less likely to short out, and if it does, it is less likely to start a fire or damage the equipment that is plugged into it.

Why does my extension cord get hot?
When one part of an extension cord gets hot, it means that there is a little more resistance at that location. If this is a plug or a socket, then that usually conducts heat to what it is plugged into, so usually they both heat up. However, since you say only one part is warm, then the issue is in that part.
What does it mean when an extension cord gets hot?
