What role does insulation play in electrical wiring?

Insulation is a crucial component in electrical wiring, primarily serving the purpose of preventing accidental contact with live wires and reducing energy loss. By covering the conductive materials, insulation creates a barrier that protects individuals and equipment from electric shocks and short circuits, thus enhancing safety in electrical installations. Additionally, insulation minimizes energy loss by preventing the escape of electrical currents, which can improve overall efficiency in electrical systems. This function is vital for both safety and energy conservation in various applications, making it an integral aspect of electrical design and installation.
