1. Introduction to Copper Tube Busbars
Definition: A copper tube busbar is an electrical conductor made from pure copper, shaped into a circular tube. Due to their exceptional conductivity and durability, they are widely used in industrial electrical systems and electronic devices.
Comparison: Compared to other types of conductors like flat copper bars and aluminum bars, copper tube busbars offer several advantages:
- Conductivity: Copper has higher conductivity than aluminum, reducing energy losses during transmission.
- Heat resistance: Copper tube busbars have better heat resistance, making them suitable for high-temperature environments.
- Mechanical strength: Copper tube busbars have high mechanical strength, capable of withstanding strong mechanical impacts.
- Flexibility: The circular shape makes copper tube busbars easy to bend and install in confined spaces. Applications:
- Industrial electrical systems: Copper tube busbars are used as busbars in distribution panels, electrical substations, manufacturing plants, etc.
- Electronic devices: Copper tube busbars are used in high-power electronic devices such as inverters, UPS, etc.
- Other industries: Oil and gas, chemicals, renewable energy, etc.
2. Structure and Operating Principle
Structure:
- Material: High-purity pure copper.
- Shape: Circular tube with various sizes depending on the application.
- Joints: Joints are usually made by welding or pressing.
- Operating principle:
- Current conduction: The current flows along the inner surface of the copper tube.
- Current distribution: The copper tube busbar distributes the current evenly to the consuming devices.
- Load bearing: Thanks to its large cross-sectional area, the copper tube busbar can withstand high currents and temperatures without damage.
3. Manufacturing Process
Stages:
