What is the Leakage in an insulated cable?

Leakage in an insulated cable refers to the unintended flow of electrical current through the insulation material or along its surface. This can occur due to factors such as moisture, damage to the insulation, or degradation over time, leading to reduced insulation resistance. Leakage can cause energy loss, interfere with the performance of electrical equipment, and pose safety hazards, including the risk of electric shock or fire. Proper installation and regular maintenance are essential to minimize leakage and ensure the integrity of insulated cables.
