Bolt Type Tension Clamp NLL Series

Product Detail

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
