Overview
Mechanical Bimetal Lug
The DTLL series mechanical bimetal lug is designed for the transition connection of aluminum or aluminum alloy cables to copper equipment terminals in medium voltage applications. These lugs feature friction-welded construction and are prefilled with jointing compound to ensure optimal conductivity and corrosion resistance. Engineered for efficiency, they utilize torque-controlled shear head bolts, eliminating the need for specialized crimping tools during installation.
