The SJD series unipolar modular safety busbars can be freely combined to meet various needs. They are made of forged aluminum, featuring fast operation speed, high current carrying capacity, and good temperature resistance. The aluminum conductor's inner cavity at the top is lined with stainless steel strips using cold-pressure welding technology to prevent electrocorrosion caused by direct contact between the aluminum conductor and the collector brush, enhancing the wear resistance of the contact. The lifespan can exceed ten years. The insulated sheath can be upgraded to a thicker type based on the actual operating conditions.
