Tension & Dead-End Clamps · Drawing-confirmed project supply
KOVYEL supplies NLL bolt-type aluminium-alloy tension clamps for anchoring overhead aluminium conductors at terminal and angle structures. NLL-1 to NLL-4 cover conductor diameters of 8–24 mm including aluminium wrapping tape, with rated breaking loads of 40–90 kN. For insulated conductor applications up to 10 kV, confirm the conductor preparation and matching insulating cover with the project requirements.
