I have taken delivery of samples of TUV solar cables 6mm2 from EB. I was curious to know if these conformed to the specs. Correct me if I am wrong but we should have tinned Cu wire 0.3mm dia x 84 strands annealed. This gives 5.94mm2 thats ok for 70A. The samples I got
a) looked genuine printed on the outside "6 sqmm DUCAB C BICC PV cable 1.5kV" but it had 84 x 0.25 dia core = 4.124mm2
b) unmarked plain black pvc with inner white sheath 83 x 0.22mm dia core = 3.193mm2
Grossly under rated 40-50% - fire risk, insurance issue? the strands seemed springy - not annealed - fragile at crimp joints if flapping around in the wind. Is it proper UV resistant sheath or will it crack up in the direct sun (like cheap domestic cable does)
Clearly some very important discrepancies - fertile ground for the Cheap Charlie to profit?
Before I go Nuclear with the suppliers, has anyone else noticed this issue as I took one look at the cable construction and immediately thought that its an obvious area for cheating.
