Laminated Copper Insulated Busbars

Laminated Copper Insulated Busbars are an advanced electrical conductor system consisting of multiple layers of copper foil laminated and insulated. This design allows the wire to have higher electrical conductivity and greater corrosion resistance. At the same time, the insulation layer can effectively prevent the occurrence of circuit short-circuit and leakage phenomenon, which improves the safety and stability of the electrical system.Laminated Copper Insulated Busbars are widely used in electric power transmission and distribution, frequency converters, electric vehicle charging piles and other fields. Its efficient conductivity and reliable safety performance make it an ideal choice for modern electrical systems. Compared with traditional electrical conductors, it has smaller size and weight, higher electrical and thermal conductivity. In addition, it has the advantages of easy installation and low maintenance costs, making it one of the most important components commonly used in electrical engineering.

• Structure:

• Copper Layers: Multiple thin layers of copper (or other conductive materials) are stacked and laminated together.

• Insulation: Each layer of copper is separated by an insulating material, which can include polyester films, polyimide, or other suitable insulators.

• Encapsulation: The entire assembly is often encapsulated in an insulating outer layer to protect against environmental factors and electrical faults.

• Function:

• Current Distribution: They efficiently distribute electrical current between different components within an electrical system.

• Reduced Inductance: The laminated structure minimizes inductance, which is beneficial in high-frequency and high-speed applications.

• Advantages:

• Improved Electrical Performance: Lower inductance and resistance compared to traditional busbars, resulting in better electrical performance and reduced power losses.

• Compact Design: The laminated construction allows for a more compact design, saving space in electrical assemblies.
