NLL NLD Bolt Type Tension Clamp for Overhead Power Conductor

Bolt type tension clamp is the most widely used strain fitting for distribution power lines. It clamps the conductor steadily by bolt mechanical pressure to fix wires on terminal towers, corner towers and strain sections. Simple structure, uniform clamping force and no damage to conductors. Easy to install and reusable. With excellent anti-corrosion performance, it ensures stable tension locking and prevents slipping or breaking for long-term outdoor power line operation.
