Bolt Type Tension Clamp Nll Series

Bolt type tension clamp is a kind of tension clamp

The strain clamp refers to the hardware used to fix the wire to withstand the tension of the wire and hang the wire to the strain string or the tower.

Used for corners, splices, and terminal connections. Spiral aluminum clad steel wire has extremely strong tensile strength,no concentrated stress,

and protects the optical cable and assists in damping vibration. The complete set of optical cable tensile hardware includes: tensile pre-twisted wire

and matching connecting hardware. The grip strength of the clamp is not less than 95% of the rated tensile strength of the optical cable, which is

convenient and quick to install, which reduces the construction cost. It is suitable for ADSS optical cable line with span ≤100m and line turning angle <25°.

NLL series bolt type tension clamp is mainly used in standing electric power line or substation, stationary conduction line and lightning conductor and

also be used in jointing the strain insulators by joining hardware or jointing the lightning conductor with the perch.

It is designed for aerial lines up to 30kV.

1) Be suitable for fixing insulated aluminum conductor or naked aluminum conductor on the rotate angle or insulator of terminal strain pole, to fix

and tighten the aerial conductor.

2) Material: body, keeper – aluminum alloy, split pin – stainless steel, others – hot-dip galvanized steel.

3) Grip strength of the clamp is more than 95% break strength of the conductor.

4) Insulation cover and strain clamp used together for insulation protection
