Tension-spring connection system
The tension spring functions in a manner similar to the conventional clamping yoke. The tension spring also separates the mechanical and electrical functions. The tension spring is made of high-quality, rust- and acid-resistant steel. It pulls the wire against the galvanized copper busbar. Low contact resistance and high corrosion resistance are enabled by the tin surface of the busbar. These are maintained over a long duration due to the compensatory effect.
