[0002] As modern industrial systems continue to pursue efficiency and reliability, the use of electronic control devices is becoming increasingly widespread. High-current terminal blocks are electrical components used to connect cables. They are capable of carrying high current loads and typically require a large conductive cross-sectional area to reduce resistance and voltage drop. High-current terminals are primarily used to connect and transmit high-power currents and are widely used in industries such as industry, electricity, and transportation to meet the connection needs of high-power equipment.
