Solar DC Cables
SanFlex cables are designed for connecting photovoltaic power supply systems. They are dedicated to the photovoltaic system direct current (D.C.) side with a nominal D.C. voltage of a 1.5kV. These cables can be used indoor & outdoor for flexible and fixed installations with high mechanical strength in extreme weather conditions. cables are designed to withstand the demanding environmental conditions that arise in any fixed, mobile, roof or architecturally integrated photovoltaic installation.
