Solar Cables

A category wioth increasing demand, the solar cables from Polysure are getting more and more attention everyday owing to the fact that this is the most promising environment friendly industry and is expected to have a significant role in resolving the world’s energy crisis. With diminishing production costs, users view this current transmission medium of solar energy power generation as cheap, clean and reliable.

 

Polysure PV Solar 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.

Applications

These cables are suitable for permanent outdoor long-term use, under variable and harsh climate conditions. They are designed and tested to operate at a normal maximum conductor temperature of 90°C and for 20,000 hours up to 120°C. Therefore, the expected period use is 30 years under normal usage conditions.
