Width of sensor cable trenches
o Using a cable plow, the cutting blade should be at a minimum, twice the width of the
outer diameter of the sensor cable.
▪
Cable diameter: 16.39 mm (.65 in)
▪
Plow blade diameter width (minimum): 32.8 mm (1.3 in)
▪
Observe a minimum cable installation bend radius of 15 cm (6 in)
o Use a trenching machine for sites or areas where the cable plow will not work. The
trench width is determined by the width of the cutting teeth. Most are 10 to 15.2 cm (4 to
6 in) wide, which is more than required.
▪
All installs utilizing a trench should have cable marker/caution tape installed 9 cm
(3.5 in) above the TDSC.
