application:
nll series of bolt type al-alloy extension wire-clamp is applied to power-transmission line for fastening the overhead insulation al-lead or exposed al lead onto insulator of corner or terminal extension pole so as to fix or tighten the overhead lead.
stucture feature:
the wire-clamp's casing adopts special al alloy with properties of high-strength, anti-oxidization to be die-casting for forming.
adopts advanced design idea and prohuction technology that makes casing, lead, u-shape screw, pressure-article compact and have good contact in addition to big gripping-power after being assembled.
the installation and use is simple, wire-clamp's strength is high, without any magnetic hysteresis loss, the energy-conservation effect is well.
