Nowadays, more and more people rely on the electricity, and also pay more attentions to the safety of power supply of the electrical network, especially the town network. Therefore, one of the most effective measures to be taken is to adopt the insulation conductor instead of the bare wire in terms of power supply of town network. Meanwhile, corresponding measures should also be taken for fitting to make it have insulating function, which have two ways one is to use the insulating materials, and to design such kind of fitting which has the insulating function; the other is to design the insulating cover so as to reach the effect of insulation.
Application: NXJ four-core-centralized strain clamp is suitable for the end of aerial wire terminal, it action is fixing or tightening the insulation conductor. The clamp has been designed four core parallel groove, after clamping the four insulation conductor (not remove the insulation layer) tighten up the bolt to have large grip strength.
