Key points for selecting materials for copper bars to achieve cost reduction.

Selection knowledge for copper bars (main bars and branch bars): Choose considering material properties! Improve efficiency!

【Before】 ■Types of copper materials used in copper bars When using copper bars, while there may be a selection of surface treatments such as nickel plating or tin plating, we had never delved into the materials of the copper itself. As a result, we were selecting and adopting copper materials without knowing whether they were suitable for the operating environment of our panels. ↓ 【After】 ■Types of copper materials used in copper bars and conductivity When selecting copper bars, determining the material based on the internationally accepted annealed standard soft copper conductivity, known as IACS, allows for efficient current flow. While there may not be much difference in standard copper bars, it is possible to make selections that achieve energy savings in custom copper bars designed to carry high-capacity power. *For more details, please refer to the catalog or feel free to contact us.

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

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

Knowledge for Selecting Copper Bars (Main Bars and Branch Bars) - Reduce Processing Costs and Lower Overall Costs!

【Before】 When determining the dimensions of copper bars used for carrying large currents, such as those in power panels, there were no clear internal standards, and we were directly repurposing from past drawings. The large cross-sectional area copper bars were not standard products from manufacturers, and we were ordering them as custom items each time, which led to high costs for copper materials and processing to specified dimensions, becoming a problem. ↓ 【After】 The key point in selecting custom copper bars is that referring to the size charts from material manufacturers can help reduce processing costs. Since the dimensions of copper bars intended for carrying current do not require high precision in material dimensions, it is efficient to design them as closely as possible to the original material dimensions. Although there is a standard length for each material piece, determining the dimensions of copper bars that do not require complex machining can achieve cost reductions. *For more details, please refer to the catalog or feel free to contact us.*

Key points for selecting the "cross-sectional area" of copper bars to achieve cost reduction.

Key points for selecting the "cross-sectional area" of copper bars to achieve cost reduction.

Knowledge for Selecting Copper Bars (Main Bars and Branch Bars) - Ensuring Safety by Selecting According to Standards

【Before】 The selection of the cross-sectional area of the copper bar based on the flowing current has been referenced from the catalog values of copper bar manufacturers. However, since the allowable current values differ among manufacturers even for the same cross-sectional area, we have prioritized safety by selecting larger cross-sectional area copper bars each time, which has led to increased material costs. ↓ 【After】 When you want to determine the cross-sectional area of the copper bar based on the rated current, it is common to refer to the Japan Electric Power Distribution Control System Industry Association standard JSIA303 for cabinet-type distribution boards (III04-2). When prioritizing safety, you can select the necessary cross-sectional area by applying the above formula. *For more details, please refer to the catalog or feel free to contact us.*

Key points for selecting the "height" and "width" of copper bars to achieve cost reduction.

Key points for selecting the "height" and "width" of copper bars to achieve cost reduction.

Selection knowledge for copper bars (main bars and branch bars): Choose standard dimensions for better quality products!

【Before】 The copper bar determines its cross-sectional area (height × width) based on the flowing electrical capacity, but the "height" and "width" that determine the cross-sectional area are fixed combinations of standard dimensions. If the copper bar is designed outside the "height" and "width" specified in the table above, it will deviate from standard products, resulting in increased costs and lead times. ↓ 【After】 Once the required cross-sectional area of the copper bar is determined, the next step is to decide on the dimensions of the copper bar to be used. At this time, even within the standard dimensions (height × width), for a "height" of 3mm, the "width" can be 12mm or 15mm, and for a "height" of 4mm, the "width" can be 12mm, 15mm, or 20mm, allowing for selection from standard copper bar dimensions. This enables cost reduction and shorter lead times for material procurement from the design stage. *For more details, please refer to the catalog or feel free to contact us.*

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

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.*

Technical Information: What are the benefits of copper rolled screws?

Technical Information: What are the benefits of copper rolled screws?

The importance of copper round bar processing technology and its quality control.

Processing of copper round bars requires precise machining technology, particularly focusing on the use of 5-axis machining centers and CNC lathes. In screw machining, there are two types: rolling and cutting, each with its own advantages, but some methods may take longer. Additionally, strict quality control is implemented, and only products that pass inspection using ring gauges are shipped. This ensures the high quality of copper products.
