Mechanical cable lugs play a vital role in maintaining the integrity of electrical connections. These lugs, crafted from durable metals such as copper or aluminum, are used to connect cables securely to terminals and connectors. They are typically fastened with screws or bolts, ensuring a stable and reliable connection that can handle high currents. By preventing loose or faulty connections, mechanical cable lugs help safeguard against electrical failures and enhance the overall safety and efficiency of electrical systems. Proper selection and installation are key to optimal performance.
