5kV Teck 90 Cable in Rigid Steel Conduit
5kV Teck 90 Cable in Rigid Steel Conduit
(OP)
Hi there,
We are planning to install a 5kV TECK 90 Cable buried in a cable trench. One of the client requirements is that any cables buried in a cable trench in a vehicular area needs to be installed in a rigid steel conduit.
Now, my question is whether a 5kV TECK 90 cable can be installed in a rigid steel conduit underground. Is this a common practise among industrial clients?
I was told that the 5kV TECK 90 cable can be damaged during cable pulling if installed in a conduit.
Comments anyone?
Thanks in advance.

I would not say it is common, but it is sometimes done. Just mind the bending radius.

Teck cable is generally installed in conduit to provide extra mechanical protection.
Consider bell ends on the conduit instead of bushings. Beware of dirt and stones entering the conduit with the Teck cable.

It is a 5kV TECK 90 3C-500MCM Non-Shielded cable. This cable has a total diameter of 2.78 inches (including the outer jacket). My concern is the cable bending of that cable in a rigid steel conduit underground (i.e. buried trench).

If you want more guidance on design on the conduit system, I'd contact your local Okonite office. They like to find ways for people to use more C-L-X so are generally helpful. (No affiliation.)

I do not have my book with me. Maybe someone can verify this.

Since "Teck Cable" is a CSA spec, I'm assuming this work is in Canada.
