Laminated Busbars

Reliability, efficiency, and safety are non-negotiables regarding power distribution. Laminated busbars provide a highly effective solution to these critical needs, ensuring electrical systems run smoothly and safely across various industries. Whether you’re in the automotive, renewable energy, or industrial sectors, laminated busbars can address several pain points that traditional wiring and busbar systems may not.  

Material Core

Copper, Aluminum, or Copper-Alloy 

Tin Coating Thickness

5-10 microns 

Bus Bar Thickness

0.5 mm to 5 mm (customizable) 

Bus Bar Width

5 mm to 100 mm (customizable) 

Electrical Conductivity

> 58 MS/m (for copper), > 35 MS/m (for aluminum) 

Product Description

Laminated bus bars are designed to handle high currents without significant heat buildup. Traditional copper bus bars or wires can suffer from resistance-related heating when carrying large currents. Laminated bus bars, however, are engineered to minimize this resistance by using multiple layers of conductive materials. This design allows them to handle higher currents more efficiently, reducing the risk of overheating and ensuring that your systems stay safe under load. 

Thermal Conductivity

380 W/m·K (for copper), 230 W/m·K (for aluminum) 

Voltage Rating

Up to 1000 V (customizable based on application) 

Current Rating

Up to 1000 A (depending on design and cooling) 

Operating Temperature

-40°C to 150°C (depending on insulation) 

Corrosion Resistance

High resistance to moisture, chemicals, and salt 

Mechanical Strength

Tensile strength of up to 210 MPa (for copper) 

Plating Adhesion

Strong adhesion, meeting IPC-4552 standards 

Surface Finish

Smooth, uniform with optional matte or shiny finish 

Customization Options

Custom shapes, sizes, current ratings, and coatings 

Standards Compliance

RoHS, UL, IEC 60269, and other industry standards 

Technical Advantages

In industries where space is at a premium, such as electric vehicles or compact machinery, the compact design of laminated busbars is a game-changer. Their laminated structure allows for a dense yet organized power distribution layout that would be impossible with bulky traditional busbars or cables. This space efficiency ensures that more components fit within a smaller area while maintaining optimal performance. 

Durability is critical in any electrical system, especially in harsh environments. Laminated busbars resist mechanical stress, vibrations, and environmental factors like humidity and corrosive elements. This makes them ideal for industrial and automotive applications where components must endure extreme conditions. With their robust construction, laminated busbars offer long-term reliability and reduce the need for costly replacements and maintenance.

Customizable Solutions and EMI Shielding for Optimal Performance

Every power distribution system is unique, and laminated busbars offer the flexibility to be customized to fit specific needs. Whether you require a particular current rating, specific size, or enhanced insulation, laminated busbars can be engineered to meet your precise requirements. This level of customization ensures that your systems perform optimally, no matter the application. 

In sensitive electronic environments, electromagnetic interference can disrupt operations and affect performance. Laminated busbars help minimize EMI due to their layered construction, which isolates conductors and shields sensitive components. This means you can rely on stable, uninterrupted power distribution even in environments with stringent electromagnetic compatibility (EMC) requirements.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do laminated bus bars improve current handling capacity compared to traditional ones?

Laminated busbars are designed with multiple layers of conductive materials that reduce resistance. This allows them to carry higher currents more efficiently than solid copper busbars. The layered structure minimizes heat buildup, enabling laminated busbars to handle high current loads without overheating, making them ideal for large power distribution applications. 

How does the design of laminated busbars reduce mechanical stress in high-vibration environments?

Laminated busbars are constructed to withstand mechanical stress and vibration, common in industries such as automotive and aerospace. Their multi-layered construction allows the conductive layers to flex without compromising performance, making them more resistant to damage from vibration or physical impact than traditional solid busbars, which can be more prone to cracking or failure. 

What role does the insulation between layers of laminated busbars play in safety?

The insulation between the conductive layers of laminated busbars provides critical safety benefits. This insulation prevents short circuits by ensuring no direct contact between conductive paths, even under high current loads. It also protects against environmental factors, such as moisture and chemicals, which could otherwise lead to corrosion or failure of the electrical system. 

How do laminated busbars reduce electromagnetic interference (EMI) in sensitive systems?

Due to their layered design, laminated busbars help reduce electromagnetic interference (EMI). The layers of conductive material are strategically arranged to block and isolate electromagnetic signals, effectively shielding sensitive components from external noise. This is particularly crucial in telecommunications or medical devices, where EMI could disrupt performance or cause errors. 

Can laminated busbars be customized for specific voltage ratings and power configurations?

Yes, laminated busbars can be engineered to meet specific voltage ratings and power configurations. Depending on your system’s requirements, the busbars can be customized with different layer thicknesses, materials, and insulation types. This customization ensures that the busbars are optimized for the exact electrical characteristics of your application, providing reliable and efficient power distribution.
