【Copper Busbar Processing Example】 'Train Control Circuit Connection Bar' C1100-BB

【Copper Busbar Processing Example】 'Train Control Circuit Connection Bar' C1100-BB

Custom products, also accommodating difficult processing! Examples of processing using copper busbars.

Copper bus bars (copper bars) are conductive rods used to connect the power supply of distribution boards and control panels to various parts. When branching high-voltage large currents, using copper bus bars instead of cables or wires allows for efficient power supply. To prevent oxidation, they are referred to as "bus bars" in English, and are also called copper bus bars or copper bus bars. We would like to introduce a processing example of the "train control circuit connection bar" that we conducted. 【Case Overview】 ■ Product Name: Train Control Circuit Connection Bar ■ Material Details: C1100-BB ■ Size: 230×120×10 t3.0 ■ Processing Details: Cutting, piercing, table bending *For more details, please refer to the materials. Feel free to contact us!

Shunt bus bar

Shunt bus bar

A low-cost, high-precision current detection shunt that integrates a busbar and shunt resistor! It can be used for current detection in BMS and inverters!

This product is a busbar-integrated shunt that incorporates the ability to measure voltage while current is flowing. By integrating the busbar and shunt resistor into a single shape, we have achieved space-saving design. Additionally, the elimination of the need for fastening resolves the heat generation risks that have been a concern until now. The shunt busbars we offer have the following features: - They can accurately detect currents ranging from low levels to high currents, such as those from lithium-ion batteries. - We can propose custom-designed shunt busbars with a low TCR of less than 10ppm. - The shape of the busbar can be customized as per requirements.

Copper busbar water jet cutting production

Copper busbar water jet cutting production

Of course, we can promptly respond to mass production as well as special-sized distribution boards and control panels.

Conductors used in areas where high voltage and large currents flow are utilized in various applications such as distribution boards, control panels, and storage batteries. We can respond promptly not only to mass production but also to special sizes of distribution boards and control panels. We cut tough pitch copper with a purity of 99.90% or higher to various thicknesses ranging from approximately 1mm to 100mm and in various shapes as needed. Additionally, while aluminum materials are inferior in conductivity and tensile strength compared to general copper, they are lightweight and are also cut and manufactured for purposes of weight reduction and cost savings.

[Concerns about Busbars] Busbars are difficult to handle.

By converting the busbar into a circuit board, high insulation and compactness are achieved!

We have substrate-ized busbars used for high current applications. By utilizing our special technology for substrate-ization, we achieve high insulation properties and compactness. We can accommodate lengths of up to 1,000mm. Additionally, the substrate-ization is expected to provide the following benefits: - Substrate mounting of power devices such as IGBTs and SiCs - Possible attachment to devices after substrate mounting → Reduction of assembly labor and prevention of miswiring - Space-saving due to simplified substrate and wiring → Overall miniaturization of the device - The greatest advantage of substrate-ization is its high insulation performance and usability. The insulation layer using prepreg has a consistent thickness, eliminating concerns about variations in thickness like those found in powder coating. - By covering areas other than the necessary parts with the substrate, handling becomes easier, and work during transportation and installation can be done safely. *For more details, please refer to the PDF document or feel free to contact us.
