Lamella Shunts & Flexible Conductors

High-current flexible conductors engineered for resistance welding systems. Enable reliable current transfer to moving electrode assemblies with exceptional flexibility and fatigue life.

Flexible Current Transfer Solutions

Lamella shunts are essential components in resistance welding systems where current must be transferred to moving electrode assemblies. Constructed from multiple thin copper sheets (lamellae) joined at their ends, these conductors combine high current-carrying capacity with the flexibility needed to accommodate electrode movement.

The lamella design distributes flexing stress across multiple conductors, dramatically extending service life compared to solid conductors. Our shunts are engineered to withstand tens of millions of flex cycles while maintaining consistent electrical performance throughout their service life.

SVS Maverick offers lamella shunts for all major welding equipment manufacturers, as well as custom-designed solutions for specialized applications. Our engineering team can work with you to optimize shunt design for your specific current, flexibility, and space requirements.

How Lamella Shunts Work

1

Multiple Lamellae

Thin copper sheets stacked together distribute current and flex stress across multiple conductors.

2

Joined Terminals

Lamellae are brazed or soldered together at the ends to form solid terminal connections.

3

Free Flex Zone

The middle section of lamellae slides freely, allowing flexibility without fatigue damage.

Termination Options

Soldered Terminals

Traditional joining for reliable connections

Brazed Connections

High-strength joints for demanding applications
