What's the environment? Is there airflow from the right?

Some form of dendrites. Can be a metallic process or biological.

Those are definitely crystals and not mold.
I am pretty sure the only way to get crystals like that is to have them 'grow' out of a liquid.
The liquid could be draining down the conductors or could be condensing. Whatever the liquid is, it has a bunch of dissolved minerals in it.

You are correct about the dendrites. I was a metallurgical technician for a couple years. I would bet heavily against anything biological creating such perfect crystals.

If it was cold, I would say ice.

Looks a bit like tin whiskers.

Yes, it sure looks like frost to me.If it was cold, I would say ice.

Is there a water seepage problem above those wires?
Looks a lot like concrete efflorescence where water carries minerals out of the cement and they crystalize as the seepage evaporates. See it a lot in hydroelectric dams.

what is the temp ??
what is the temp ??
what is the normal ambient temp??
I have read an article about TIN crystallizing at freezing temps.

Tin doesn't look like that, though.

For the first 0.5 seconds I saw the picture I thought tin whiskers but quickly discounted it. It's not tin whiskers. It is some kind of dendrites.
Until OP tells us where this is we're limited on identifying it. Is this some kind of lab? Shop area? Data center?

Obviously those conductors feed a refrigeration system and are, therefore, cold, causing snow to form on them:lol::dunce:

I think it is some type of reaction from the current flowing in the wires.
1. Look at the base of the wires with the black ferrules it has allot of oxidation there.
2. All wire marked have the same number on them, black ferrules don't, may be different voltages.
3. Wire on left has crystals growing out of right direction, wires on left have it growing out of left direction.
So my guess is there is a magnetic attraction causing it or helping it.
