The power electricity sector relies on critical equipment throughout the entire chain — from generation (nuclear, hydroelectric, photovoltaic, wind) to transmission (substations, high-voltage systems) and distribution (medium-voltage transformers,
circuit breakers, relays, meters). At every stage, precious and rare metals — such as silver, copper, gold, nickel, and palladium — ensure conduction, switching, and system reliability. Their role is essential to guarantee the performance, safety, and continuity of power supply across industrial, commercial, residential, and transportation networks.
