Some cheap CAT 5 cable was removed from site after multiple failed connections..

The first sign of poor quality was the copper not being bonded to the aluminium core and coming off in flakes..

Examination and analysis of the metals shows how bad the cable is.

Both metals had a lot of impurity, as high as 15% in some sample of the copper.
Probably reclaimed by incineration of scrap cable without any purification of the recovered metal

The insulation produced un-acceptable emissions when burnt ( toxic fumes ? )

Unsurprisingly the company that supplied and installed the cable ceased trading last year. The owner of that ceased company when challenged
I bought it in good faith but no longer have the receipts so cannot say where I bought it

surely the first sign should have been the two metals in the cable? cat5 should be copper, not copper clad aluminium or copper clad steel.
