Women's group about to get cable (4)
I believe the answer is:
'cable' is the definition.
'women's group about to' is the wordplay.
'women's group' becomes 'wi' (Women's Institute).
'about to' becomes 're' (I've seen this in other clues).
'get' acts as a link.
(Other definitions for wire that I've seen before include "Strand of metal" , "Flexible strands of metal" , "Hand signal; breaker" , "Electrical connector" , "Thin strip of metal, may be barbed" .)
