Thank you, Tony M. When I see an English text from Alibaba, I get an immediate allergic reaction.

@ Asker Aha! Legrand is my local electrical company, just up the road, and I do a lot of work for them. Sadly, they have native FR speakers there who think they know EN better native EN speakers, and I have constant arguments with them over just this sort of thing.
'installed' is correct, really — it is a "fixed installation", i.e. no movement = less strain.
Now we know what the actual context is, 'under load', although certainly not wrong, certainly sits less easily —"under mechanical loading / mechanically-loaded' might be better.

I would not use 'dynamic' here, as these cables, although they might get moved, do not actually have a primary function of moving!!

And I think I can tell you what 'baded' was meant to be: as distinct from 'installed, it means 'used in a (patch) bay' — someone was trying to invent the word 'bayed' (not very common, and certainly to be deprecated, in EN!) but didn't quite know how to form the past participle correctly. Believe me, this is typical of Legrand! Whenever someone cites Legrand as a reference, I always first go and check if it isn't one of my own translations :-)

It is the "baded" in the English version that prompted my question here, in the hope that chargé would be closer to the truth (actually, I am translating into Polish). In the meantime, I received other advice, and the consensus is that the technical term in English would be radius under dynamic load or "dynamic," for short. The first term should have been "static," by contrast. So, neither the French and especially the English terms were correct in the original. We run into this all the time, especially when translating from Chinglish and, in general, from English texts written by non-native speakers. Je vous remercie mes amis et amies.
