I've been asked to investigate the cable life for some power cables in our outdoor installations.
Are UV-resistant cables specially treated in any way different to normal cables?
Are there different ratings of protection?
Is the damage (blistering) caused by UV or over-temperature for cables...
Hi,
can a VVVF drive radiate noise back onto the mains line?
What are the typical frequencies that are emitted?
If not into the mains, where else can this noise be radiated?
Cheers,
