Key points for selecting the "length" of copper bars to achieve cost reduction.

【Knowledge for Selecting Copper Bars (Main Bars and Branch Bars)】 The key is the length that improves the yield rate!

【Before】 The criteria for selecting copper bars during the design of distribution boards and control panels is based on the current capacity (A) flowing through them, which tends to give the most weight to the cross-sectional area (width × height). Therefore, the "length" of the copper bars is often less considered, leading to an increase in the overall cost of the panel. Among them, the copper bars connected to the main breaker have a relatively large cross-sectional area, and three bars are required for three-phase systems, making it necessary to optimize the "length" of the copper bars themselves. ↓ 【After】 By understanding the "length" dimensions of standard raw material (at the time of purchase) copper bars, it becomes possible to design the optimal "length" of copper bars. Particularly when copper bars exceeding 600mm in "length" are required, it becomes difficult to obtain the three necessary copper bars for three-phase systems from a single raw material copper bar. By considering the number of bars obtained and the yield rate from the design stage, the cost of conventional copper bars was reduced by one-fourth. *For more details, please refer to the catalog or feel free to contact us.*
