What is the main purpose of electrical insulation?

The main purpose of electrical insulation is to prevent electrical leakage and ensure safety. Electrical insulation materials are designed to resist the flow of electric current, which helps to contain the current within the intended conductive paths, such as wires and cables. This is crucial for preventing short circuits and reducing the risk of electric shock to individuals who may come into contact with electrical systems or devices. Proper insulation also helps to protect sensitive equipment by preventing unintended paths of current that could lead to damage or malfunction.

Furthermore, effective insulation contributes to the overall reliability and efficiency of electrical systems by minimizing energy loss. While insulation does play a role in protecting wires from mechanical damage and ensuring that the conductors function correctly, the primary emphasis is on maintaining safety standards and preventing electrical hazards.
