I have taken delivery of samples of TUV solar cables 6mm2. 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. 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) un marked plain black with inner white sheath 83 x 0.22mm dia core = 3.193mm2
Clearly a very important discrepancy
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.
BTW Ive already been reprimanded for over thinking a topic on this board. Is my concern here justified?
