2, wire clamp depends on the fastening degree of workmen's bolt to the grip of wire, likely, because human error causes grip of clamp deficiency, leads to electric power accident.
3, can only apply and steel reinforced aluminium conductor, can not apply and insulated wire.
Also there is wedge strain resistance cable clamp, rely on the tension force of wire self, tension wedge pressure tongue, the self-tightening pattern that formation is drawn tighter and tighter automatically simultaneously.Its shortcoming is as follows:
1,, during wire relaxes, self tension force deficiency, cannot form self-tightening, can come off on the contrary.
2, wedge-shaped enclosure belly has opening, and when wire is stressed while having the drift angle of ventrad, that presses tongue to have to come off from opening may.
While 3, using, likely cause insulated hull and the dislocation of aluminium core on insulated wire, produce the phenomenon of " taking out skin lacing wire ", damage wires, and cause the sliding race of wire.
