The wedge-type tension clamps of types NK-120, NK-160, and NK-210 are designed for securing non-insulated conductors to insulating suspensions of anchor, anchor-angle, and terminal supports. The strength of the conductor fixation in the clamp is 95% of the conductor's breaking force. Manufactured according to TU 3449-001-52819896-2010.
