Busbar system reliability is ensured not only by selecting the correct conductor, but also by applying the correct and verifiable tightening force. GERSAN Smart Bolt technology confirms joint integrity through its visual indicator, which turns black when the calibrated torque value of 90 Nm is reached, ensuring that installation relies on engineering control rather than assumption.Busbar system reliability is ensured not only by selecting the correct conductor, but also by applying the correct and verifiable tightening force.
