ᐅ Installing Satellite and Underground Cables into the House

Hello everyone,

The next topic in our house construction is the electrical work. I want to run three underground cables to the outside and four satellite cables into the house. Is it sufficient to just use a conduit and then fill it with expanding foam, or is that waterproof? Or do I need to use special sealing glands?

Thanks for your help

Then PVC pipes will be sufficient for you as well.

Theoretically, I would use a pipe like this, drill it at a downward angle, and then fill the pipe around the cables with well water-resistant foam (filling a bit inside and outside).

Edit: Oh, and of course, keep electrical and data cables separate.

Then you better use Kabuflex pipes. They are suitable for underground installation.

Ok, are these harder than the ones I also use as conduit?

My pipe is labeled "highspeed VDE" and is relatively stiff and durable.

That does not necessarily mean that they are suitable for underground installation.

I assume you already know that installations on electrical systems are reserved for licensed electricians according to NAV § 13?
Is it enough to just use an empty conduit and then seal it afterward with expanding foam for wells? Is that waterproof, or do you have to use special cable glands?

Certainly not with pressurized water.

If you have to rely on forum experience for details like this, it raises the question about the safety of the power and satellite cables.

By the way: conventionally directly grounded rooftop antennas rank significantly higher in safety compared to garden or outdoor antennas. Grounding and equipotential bonding are integral parts of the electrical system.
