 Conduit
Im looking to run CAT5 outdoor cable to a new office 30 metres away. It is set to run underground in a trench the Electric Company is about to lay.
Should the CAT5 also have a shield or trunking cable around it? If so what kind?
Also sorry about this one but what is conduit? I keep reading it mentioned on various web sites but am not 100% what it is.

Hi, Joe!

I wouldn't recommend using copper cable in your case. Use fiber optic cable instead with media converters at the ends.

This way you will avoid possible problems with EMI from the electrical cables.

Use dielectric optical cable and place it into a rigid PVC conduit. By the way, "conduit" is a raceway of circular cross-section, through which cables can be pulled.

For separation from electrical cables, see this link:
