The following 3 types of cables are used in a MedContour
ultrasound head (for beauty salon) in a flexible plastic
conduit with steel wire coil support. The conduit/cables experience
some heat from the ultrasound head as well as constant
movement.
I need to replace the cables as one of them was worn out
and thought of changing all of them as I noticed they are all hardening near the
ultrasound head due to heat / movement and it's too much
work pulling them apart again at a later stage :
Here are the original cables/ some writing on them (as well as I could
decipher it) and below are the alternatives I found as I can't find originals
locally unless I buy bulk)
(1)Baldassari Special CAVI LIYCY 4x2x0,25 A1997 IEC 60332.-3-24 CE2 20-22 ZI

(there's 3 types of LiYCY cable they make but from the color this should be
it)

(3)For the RG174 I found several companies which add the BNC
connectors, so I'll just buy them made to length I need
as I don't need or want to get into buying good crimping tools
as would seldom need them.
Was wondering whether someone with more experience in cables
could comment if there are any better alternatives considering
the ultrasound heating and cable conduit being moved all the time
(outer insulation and shield almost completely broken in the conduit )?
