Insulatorfunktion

Insulatorfunktion refers to the primary role of materials that resist the flow of electric current. These substances, known as electrical insulators, are crucial in electrical systems for safety and functionality. Their effectiveness stems from a high electrical resistance, meaning that very few free charge carriers are available to move and conduct electricity. This property prevents unintended electrical pathways, thereby protecting users from electric shock and safeguarding components from short circuits. Common examples of materials exhibiting insulatorfunktion include rubber, plastic, glass, and ceramics. These materials are widely employed in applications such as the sheathing of electrical wires, the construction of electrical components like switches and sockets, and the insulation of high-voltage equipment. The ability of a material to perform its insulatorfunktion is quantified by its dielectric strength, which indicates the maximum electric field it can withstand before breakdown occurs. Proper insulatorfunktion is therefore a fundamental requirement for reliable and safe electrical engineering.
