The CAT5 standard doesn't specify whether it's screened or not.

You will typically find two types available, UTP (Unshielded Twisted Pair)
and STP (Shielded Twisted Pair), the STP having a screen.

STP is a lot less flexible (in the sense of bendability, not application),
and I'd be surprised if it were needed in a domestic environment. I've only
seen it used round HIGH voltage stuff before.

As to whether 40mm is enough - rather depends on the application. If you're
talking about 100Mb/sec computer data / audio / video, it could well be.
The
tolerances for Gigabit ethernet are a lot tighter.

Subject: [ukha_d] Cabling (Cat5 and Power) in trunking


I’m thinking about running the power and a few lengths of Cat5
around my
workshop in trunking (the fat kind you get in offices where the sockets are
mounted into it). I’m running a 32A ring main and also a few runs
for other
machinery. My question relates to running Cat5 and power fairly close
together (something like 40mm separation I guess – but in parallel).
Is this
far enough apart? I guess it must be as this kind of trunking is so common
in offices – but is the Cat5 screened????
