Coupling
To install ConQuest ® toneable conduit, employ standard HDPE conduit installation
procedures. When conduit needs to be coupled, be certain to over pull the two
ends by a minimum of two feet so the tone wire can be spliced at the coupled joint.
To couple the conduit and splice the tone wire to maintain electrical continuity, these
procedures are recommended:
The tone wire should be separated from the conduit end for a minimum length
of 12 inches + 2.5x the length of the coupler. For example, if the coupler being
used is five inches long, it should be separated from the conduit end for a
minimum of 24.5 inches: 12 inches + (5 inches x 2.5). This is shown in Figure 2.
Separate the tone wire jacket from the conduit using a utility knife, as shown in Figure 3. Make the cut as close to the
conduit wall as possible, to not leave a ridge on the conduit when coupling the conduit. This is best accomplished by
scoring the jacket at the conduit several times. Generally, on the third or fourth pass of the knife, the wire jacket will
completely separate. Attempting to separate the tone wire jacket from the conduit in one pass will usually result in the
knife cutting the jacket up into the tone wire, which could result in future corrosion.
If a ridge remains after separating the tone wire from the conduit,
shave any remaining HDPE with the knife until smooth. Shave the
conduit for a length of 10 inches, which should be enough for
the coupler length requirements. Should the coupler be longer
than this, continue shaving the ridge until it matches half the
length of the coupler.
In order to splice the tone wire, begin by cutting the conduits
perpendicular with conduit cutters 12 inches from the end, as
shown in Figure 4, so there is a clean face for coupling the
conduit. The ends of each conduit should now overlap slightly to
allow coupling of the conduits.
