NILED, european manufacturer, develop and supply ” mechanical screw lugs ” and junction “mechanical screws connectors” for more than 70 years. No torque wrench is required for bolt tightening : The head (or screw) will shear itself off at the appropriate torque moment. So, shear head bolts (or shear-head screws) ensure precise tightening control of the mechanical screw lugs. Moreover, installations are easy, quick, and secure. V -bolts positions are proposed according cables to connect for highest electrical contact. In addition, inner grooving ensures high level cross-line conductivity of stranded conductors due to increased current flow from inner to external strands. Mechanical screw lugs and connectors  can be used for medium voltage or low voltage application . Niled propose a maintaining key “CM” for easier installation of the mechanical shear head connectors -junction type or shear-head mechanical bolted lugs).

The proposed ranges of NILED shear bolts mechanical lugs and connectors include very wide ranges of cross sections. That is why electrical installer will find LV and MV solutions, and specific range of shear head mechanical connectors with required dimensions or forms, for all classes of conductors. Furthermore, Niled can propose on request customized solutions, special types and dedicated designs. The connectors are used for aluminium or copper cables conform to IEC60228.
