NILED is a european manufacturer for ” mechanical screw lugs ” and junction “shear screws connectors” for more than 70 years. No torque key is required for bolt adjustment : The head of the bolts (or screws) will shear theym-selves off at the appropriate torque. So, shear head bolts (or shear-head screws) ensure precise tightening control of the mechanical screw lugs. Moreover, installation is easy, quick, and secure. V -shaped screws solutions are proposed according conductors charcateristics for the best electrical performance. In addition, inner grooves ensure high level cross-line conductivity of the stranded conductors because increased current flow from inner to outer strands. Shear bolts or screw mechanical connectors (terminal lugs or junction splices) 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.
