电极接杆（Electrode Pole）

选用强度高、耐磨性能、高导电率的合金材质制造。根据焊接工艺，采用多级柔性冷成型技术生产，有效保证了其传输电流、冷却、承压的能力，使电极接杆的更换频率降低。

We choose alloy materials which have high strength, good abrasion resistance and high conductivity . According to welding technology, multilevel soft cold extrusion processing molding technology can assure the capacity of transmit current、cooling、enduring load,and reduces the frequency of changing electrode pole to its minimum level
