1. A method for manufacturing a safety busbar, the method comprising:
placing a second conductor on each of two opposite ends of a first conductor;
performing linear friction welding between the first conductor and the second conductor; and
cutting the first conductor to a predetermined depth,
wherein the method further comprises:
installing a spacer on the first conductor; and
installing a tube on the first conductor,
wherein the tube surrounds the first conductor with the spacer interposed between the first conductor and the tube so that the spacer is placed orthogonally in the center of the tube,
wherein the tube is formed of an insulator including rubber or silicone in a protrusion shape,
wherein the tube is fixed to the first conductor using thermocompression and an adhesive on two opposite ends of the tube, and
wherein a space is formed between the tube and the first conductor.
