Hi, We are working on a Solar installation in the UK and have been asked to replace the string cable terminations, 6mm² yellow insulated ring terminals that are bolted to a common busbar. The reason stated is that the insulated terminals are not rated for the string voltages, 1000Vdc STC. Having searched the internet I have found that Cembre insulated terminals have a Maximum Voltage Rating – 0.6kV | 600 Volts | LV Low Voltage.
It is assumed that the LV Low Voltage is the AC voltage and would it be correct to assume that the DC rating would be 1.5x the LV Low Voltage rating i.e. 1.5x600=900Vdc?
See attached image, sorry for the quality of the image.
Any help regarding this would be appreciated.
