Insulation & Sheath
Cross-linked materials (e.g., XLPO, XLPE)
Low smoke, zero halogen (LSZH) for fire safety
UV and weather resistance for outdoor use34
Electrical Ratings
Nominal DC voltage: 1.5 kV (conductor-to-ground)
Operating temperature
90°C continuous (20,000 hours)
120°C short-term (emergency conditions)12
Mechanical & Environmental Performance
Flexibility for installation in PV arrays
Resistance to abrasion, ozone, and chemicals
25-year minimum service life under normal conditions
Applications
PV system DC side wiring (between solar panels, inverters, and batteries)
Ground-mounted and rooftop solar installations
Harsh environments (high UV exposure, temperature fluctuations)
