Rise；The other end connection core of core crimping；
One section of the drawing head is connected with drawing head connector.
Preferably, the nut outside diameter is more than the through hole internal diameter.
Preferably, the drawing head is screwed on the drawing head connector by screw thread, and connecting portion is equipped with fluid sealant
Circle.
Preferably, the core aluminium hydraulic pressed connecting pipe is to crimp with core connection mode.
Preferably, the cable steel wire is armature of cable steel wire.
Preferably, the cable drawing head further includes heat-shrinkable T bush, and the heat-shrinkable T bush is wrapped in drawing head, connection
Outside component and cable.
The beneficial effects of the utility model are：The steel wire in the construction of cable is made full use of, considerably increases cable drawing head
Intensity.Compared with traditional drawing head, the utility model drawing head can bear the tractive force of bigger, be avoided that because pulling force is excessive
The problems such as caused rupture, cable water inlet, ensure that the quality and safety of cable laying.In common cable laying project,
Its reliability higher, also more effectively can prevent cable from intaking；And in the engineering of the high requests such as high tower deep-well, its performance also can
Meet the requirements.Its production cost is low, applied widely, safe, with good economic efficiency.
