[TowerTalk] Pulling wire

[K4BEV at aol.com]

Some FB ideas have been presented in the "Pull rope in PVC" thread.

Also, ALWAYS:
Pull AT LEAST 10% spares for control wires and coaxial cables.
Go up AT LEAST one size larger conduit than needed. There are tables 
indicating how much of what will fit in which size of conduit.
Label everything at both ends.
Make a drawing, or (better) take a picture of the run before its covered, if 
buried.
Use stranded THHN or similar (has a slick jacket) for control wires. MTW 
(soft jacket) is great for making bends in a panel, but NO fun to pull through 
anything.
One word -- Wire Lube! I like Ideal Yellow 77 - Works great, lasts a long 
time, won't hurt the insulation.
Pull more out than needed at the end of the run and carefully inspect every 
wire. If ANY are roughed up pull the entire run back out and find the problem. 
This is almost never a problem with plastic pipe, but a burr missed when 
cutting steel conduit can create real problems later.
90 degree fittings are OK for control wire (no more that 360 deg total) , but 
use sweeps if coax is involved.

If you tape your wires together before a pull - Remove ALL tape before it 
enters the conduit.
If you ever need to remove a wire, or use one as a pull, you won't be able to 
if the wires are taped together.

Have fun,
