High voltage insulators are a basic component, part of the electrical system, which protect the system from electric shocks and prevent the prerequisites for accidents, fires or problems. They are a cylindrical ceramic insulator with a drilled hole of different diameter. They are mainly used for wrapping cables or other equipment.
The main property of insulators is to stop or limit the free flow of current, that is, little electric current is allowed to pass through it. Unlike wires and semiconductors, high voltage insulators have a high electrical resistance. They are used for networks above 1kV where there is a high risk of electric shock. High voltage insulators also help reduce the risk of short circuits, which can cause significant damage to electrical systems.
