First I replace all the isolators that have sold, then I raise the tape and only then connect the tape, I verify the passage of current: if I find the dispersions or problems of breakage, I cut the tape, take the damaged part and replace it using the buckles Rif. 24, Rif. 22 o Rif. 39.
You ran the cable Ref. 28 or even the tape in contact with other cables that carry signals: avoid it to avoid malfunctions to these last devices.
You have a dispersion on the ground, you have to localize it and eliminate it. Test the brown cable Ref. 28 ; remove it from being connected to the fence and turn on the electrifier: if you get the same situation, the dispersion is in the cable that you have stretched in the pose (if you use non-insulated cables you will surely have the problem); if, on the other hand, with the cable that is not connected, everything is done again, the problem is on the fence.
