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

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

【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 consideration to the cross-sectional area (width × height). As a result, the "length" of the copper bars is often less considered, leading to an increase in the overall cost of the panel. In particular, the copper bars connected to the main breaker have a relatively large cross-sectional area and require three bars for a three-phase system, 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" for the copper bars. Especially when copper bars longer than 600mm are required, it becomes difficult to obtain the three necessary copper bars for a three-phase system 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 has been reduced by one-fourth. *For more details, please refer to the catalog or feel free to contact us.*
