The 6mm2 DC cable is specialized in
PV stations with the maximum ambient temperature of 90 ℃
while operating. According to 2PfG 1169/08. 2007, the cable is suitable for the
maximum allowable DC voltage of 1.8 KV (in non-grounded system, core-to-core).
Application Scope
According to 2PfG 1169/08. 2007, the 6mm2 DC cable is suitable for single-core flexible cables (wires) with a maximum allowable DC voltage of 1.8 KV (core-to-core, non-grounded system) and used on the DC side in photovoltaic systems. This product is suitable for use under Class II safety level. The ambient temperature of cable operation is as high as 90 ℃, and multiple cables can be used in parallel.
