While measuring tension of lines

it’s not convenient to install tension sensor directly. In order to solve this problem

a tension measuring device is designed. The device adopts friction clamping

and it can be installed on transmission lines easily without power off. The tension of transmission lines can be measured by tension sensor. Experimental study and analysis prove that the device can sustain tension of high voltage transmission lines without mechanical sliding

without damage to lines in operation process and without influences to running state of lines.
