Leaky cables

[jaime ricardo]

Can leaky coaxial cables be installed in Class 1 Division 1 classified areas?

Leaky, as you probably know, is a brand name and not descriptive of if it will allow passage or migration of gases.There are some coax cables rated for hazardous area atmospheres but I have never had occasion to use them..Check you cable spec it show usage compliance.

1. in conduit, with XP installation
2. Other wiring methods are available of the circuit qualifies as IS.

In the RF world, a leaky coax cable is used to radiate an RF signal where there is poor reception.

Right on Tom ,I should have said style rather than brand my bad once again.That does bring up the question can these leaky cables function within a conduit in radiating RF?

In non-metallic conduit yes. In metal conduit no, just serves as another shield replacing the purposely leaky one in the cable.

Good work Tom. I was wondering if someone was going to get that! :thumbsup:

Are there any part numbers, examples or references to leaky co-ax cables?

Radiax is one example:

Now that's some serious co-ax cable, up to 1-5/8 inch diameter and up to 300kW. I have no idea of how it would be used or why big power would be required.

We use to tell apprentices to put a bucket under it so the RF doesnt leak onto the floor. Some were dumb enough to do it. ( They didnt last long):lol:
