Figure 27. Cable Tie Installation
When the transducer cable is routed from the fence to pass around a fence post or standard and
return again to the fence, be sure to leave a slightly loose, but not drooping, loop. Otherwise, when the
fence is stressed, the cable can chafe, wearing through the cable jacket.
Example: You should be able to just push a pencil between the fence post and transducer cable.
See Figure 28. If the fence post or standard has a rough or sharp surface, additional insulation must be
installed on the transducer cable to prevent damage from long term abrasion. A damaged jacket will
permit moisture penetration and allow undesirable interference into the pre-amp. Installation of a
spiral wrapped flexible protective material, such as the Panduit 1/8 T12F-0, or similar, is recommended.
The protective material must be black weather resistant polyethylene.
Cable ties must not be tightened so tight that the conductor insulation is damaged. To prevent this
from occurring, do not use tie wrap Installation tools. Use your hands to draw each tie up until snug.
Care must be taken when installing cable ties to assure the transducer cable is not tied to the fence
where sharp metal and/or excess galvanizing material may protrude and damage the cable.
To allow for future transducer cable repair, it is advisable to provide service loops (one foot offsets)
approximately every 40 to 50 feet at the fence posts. See Figure 29.
