Professional needing conduit for cables, is charged for its fabrication (10)
I believe the answer is:
production
'fabrication' is the definition.
(thesaurus)
'professional needing conduit for cables' is the wordplay.
'professional' becomes 'pro' (abbreviation).
'needing' means one lot of letters go next to another.
'conduit' becomes 'duct' (duct is a kind of conduit).
'for cables' becomes 'ion' (I can't explain this - if you can you should believe this answer much more).
'pro'+'duct'+'ion'='PRODUCTION'
'is charged for its' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for production that I've seen before include "thing manufactured" , "numbers coming off line" , "drama, say" , "... making" .)
