 cabling cat5 in pipe in ground
Is there a cat5 cable that is strong enough to be pulled into a pipe that is already in the ground , the problem are the moisture in the ground
 Answer by Dmitri Abaimov posted 30 Jun 2000
Dear Bard,

The industry-standard CAT5 cable should withstand 11 kilogramms pulling force with no degradation of its electrical/mechanical properties.

Usually, it is advised not to pull CAT5 cable through a pipe, which is more than 30 meters long and/or has more than two 90 degrees bends.


Regular CAT5 (CAT5E, CAT6) cables are made of PVC plastic, which is not intended to withstand any kind of moisture for long. So it's water, not a pulling force that will destroy the cable sooner or later.

I would recommend to use special outdoor CAT5 cable. See our FAQ section for the document on this.

With best regards,
Dmitri Abaimov, RCDD
