The utility model discloses a guaranteeing enough that the wire reduces the iron tower when being safe distance to the ground distance and exhales the title high, boring the around boring tower more on wire jumper who has built the circuit more, it belongs to transmission line and designs the field. This around boring tower more on wire jumper including body of the tower, wire cross arm, is provided with two ground wire supports on the wire cross arm, two ground wire supports distribute about the vertical center line symmetry of wire cross arm on the wire cross arm, the top of two ground wire supports is provided with the ground wire and hangs the point, be provided with three termination of group on the wire cross arm, wherein a set of termination lies in the intermediate position of wire cross arm, and remaining two sets of termination lie in the both ends of wire cross arm respectively, every termination of group is including setting up at the vertical post insulators who upwards extends of wire cross arm upper surface to and the insulator is connected to the wire that articulates on wire cross arm two sides. Adopt this around boring tower more on wire jumper, can reduce bore tower more exhale the title high, reduce construction cost, be convenient for bore selecing more simultaneously.
