With increasing power and energy density, traditional electrical screw connections face new challenges: even slight reductions in contact force can lead to higher transition resistance, localized heating, and self-reinforcing aging processes caused by settling, creeping, and relaxation of the connection. This not only affects mechanical retention but also results in unstable electrical performance and energy loss.

To address these issues, Teckentrup SLI has introduced the latest NSK-EL system, which integrates multiple functions into a single component. The system provides defined friction coefficients and proven spring elasticity, ensuring consistent clamping force during assembly and operation. Its unique geometry enables large, even pressure distribution while minimizing electrical interface surfaces, enhancing both mechanical stability and electrical performance.

Compared to traditional spring washers or two-part solutions, the NSK-EL system requires no additional components, reducing installation complexity and process risks, while simultaneously providing anti-loosening, elastic recovery, and stable contact pressure in one multifunctional solution. The system fully complies with DIN EN 17976 and VDI 2230 standards for safety-critical industries, offering safe, reliable, and energy-efficient electrical connections for e-mobility, data centers, and high-power applications.

According to Teckentrup SLI, the NSK system not only improves connection safety but also reduces failure risks and enhances long-term energy efficiency, providing customers and end-users with a more stable and reliable performance.
