What is the purpose of wire insulation?

The primary purpose of wire insulation is to prevent unintended contact with conductive materials. Insulation acts as a protective layer, typically made of materials like plastic or rubber, which keeps the conductive wire contained and minimizes the risk of electrical shock or short circuits. By ensuring that the conductive parts of a wire do not come into contact with other conductive surfaces, insulation helps maintain a safe electrical environment for both the wires and the surrounding components.

Wire insulation also contributes to preventing electrical interference and maintaining the integrity of the electrical circuit. This is especially important in environments where wires may be exposed to moisture, chemicals, or physical abrasion. The insulation ensures that electricity flows through the intended pathway, reducing safety hazards and improving overall functionality.
