4 PRE-INSTALLATION
4.3 Factory Terminated Cables
Prior to installation of long runs of cable, attach a short
length of PVC conduit to the factory terminated ends to
provide protection for the sealing pot and flexible tails
(Figure 6). Use 1 in (25 mm) minimum PVC pipe, or larger
if a 1 in or 1-1/4 in (25 mm or 32 mm) gland connector is
supplied. This will prevent damage to the sealing pot and
tails during installation.

4.4 Installation Equipment
Pulling Equipment
It is recommended that all sizes of cables be hand pulled
into position, one at a time, using pulling ropes securely
attached to the cable end. When pulling cables around
corners, hand feed cables using large sweeping bends.
Mechanical pulling equipment, such as tuggers, is not
recommended.
Sheaves
Use sheaves or pulleys of the proper diameter, where
required, to avoid damage to the cable.
Pulling Rope
Use non-stretch pulling rope with a capacity large enough
to handle the force required to pull the cable.
It is recommended that the pulling rope be attached to the
cable sheath using a series of six half-hitch knots, and the
knots and rope be securely taped to the sheath to prevent
movement during the pull.
When pulling cables from a factory terminated end, ensure
that the end is protected with a short length of PVC pipe
(see Figure 6, page 12) and securely attach the pulling
rope to the cable sheath to avoid damage to the
termination.
Install cable grips, swivels, and pulling eyes, if used,
according to manufacturer's instructions.
