Insulated wires are electrical conductors covered with a protective layer, usually made of materials like plastic or rubber. This insulation prevents electrical current from escaping and protects users from electric shocks. Insulated wires are essential in various applications, including household wiring, electronics, and industrial machinery. The insulation also helps to prevent short circuits and reduces the risk of fire hazards. Different types of insulated wires are designed for specific uses, such as thermoplastic or thermoset insulation, which can withstand different temperatures and environmental conditions. Proper insulation is crucial for safety and efficiency in electrical systems.
