ecosyn®-SEF – Operationally Safe Contact Screw Connection

ecosyn®-SEF combines a self-locking nut with an integrated conical spring washer and large contact surface. ecosyn®-SEF is a multifunctional fastening element for the safe connection of electrically conductive contacts, especially in the high-voltage range. But ecosyn®-SEF is also excellently suited for purely mechanical connections.

With vibrations applied or external loads on the clamping point, the special thread Spiralock® has proven itself against loosening of the contact screw connections. The washer reduces surface indentations due to the repeat assembly, which ensures a perfect electrical current transmission. The larger contact surface of the ecosyn®-SEF reduces the surface pressure and can be effective for long holes bridge the power transmission.
