Tension Clamp

Bi'an Electric NLL Series Tension Clamps are high-performance power fittings specifically designed for anchoring and tensioning overhead conductors and ground wires in transmission and distribution lines. As a critical component in power grid systems, they effectively bear the tensile force of conductors, fix conductors to tension towers, corners, or terminal poles, and ensure stable and reliable operation of the entire line, even under extreme weather conditions.

Our tension clamps are engineered with precision, adhering to international standards and strict quality control processes, making them suitable for various voltage levels and conductor types, and widely trusted in power construction projects worldwide.
