You may want to check with a local electrician, preferably one that does
commercial work. They use a lubricant when doing long pulls.

Subject: [TowerTalk] Pulling coax through PVC pipe
Good morning,28 years ago I buried a 1.5 inch schedule 40 PVC pipe in the
ground and ran some low loss coax and a three wire electrical control cable
(14-2 house wiring cable). The 14-2 is used to operate a remotely control
phasing box for my 80 meter four square. The coax feeds either my 160 vertical
or the 80M array.Well it’s time to replace the coax. The PVC pipe is 250 feet
long and in a straight line(thankfully). I suspect I will have to pull both
cables with the new cables tied to the end. I’ve never done this before and
could use a little advice. I googled but most of what I found started with
empty pipe and ran a “string mouse” through with a shopvac. When I installed
the cables initially, I laid them out on the ground and slipped the pipe over
them ten feet at a time. Fortunately, there is a fair amount of room left in
the pipe. The two cables did not fill up the space entirely.My first question
is if there is some sort of lubricant I should use to reduce friction?That’s
also my last question, but I know there must be several things to consider I am
betting that this group has the answers. I have a come-along, a tractor, and a
fair amount of tools. I’m just not sure how to proceed.I am eager to see what
you all have to say.Thanks.Dave,
