A copper bar protection structure (10) includes an upper housing (11) and a lower housing (12) that are engaged with each other. A receiving groove (14) is provided on each of engagement surfaces (15) of the upper housing (11) and the lower housing (12). The two receiving grooves (14) are combined into a copper bar accommodating space. A phase change material layer (30) is laid on an inner wall (13) of the receiving groove (14). The copper bar (20) is wrapped by the phase change material layer (30) when the copper bar accommodating space accommodates a copper bar (20).

A bus bar for use in conducting an alternating current may comprise multiple substantially parallel ribs and an electrically conductive attachment feature. Each rib may include a first and second end. Each rib may be provided for conducting a substantially equal portion of the current. The ribs may be spaced apart to provide gaps therebetween for airflow through the gaps. The electrically conductive attachment feature may connect the first ends of the plurality of ribs, and may be provided for attaching the plurality of ribs to an electrical component. A method for manufacturing a bus bar for use in conducting an alternating current may comprise attaching a plurality of electrically conductive strips to form a bus bar having a plurality of ribs, each rib having a first and second end, the ribs spaced apart to provide gaps therebetween for airflow through the gaps, the first ends of the plurality of ribs connected together.
