product key technologies
Core Structure
- This H1Z2Z2-K 1×50mm² PV cable adopts a durable single-core double-layer XLPO structure. Each layer features targeted design for power transmission, insulation and outdoor protection, meeting long-term solar system operation needs.
1. Flexible Tinned Copper Conductor
- 50mm² Class 5 flexible tinned copper conductor. Fine-stranded for easy bending and installation. Tinned finish resists oxidation, corrosion and salt spray, ensuring low-loss, stable DC power conduction.
2. Inner XLPO Insulation Layer
- XLPO cross-linked insulation layer provides reliable electrical isolation. It withstands 1500V DC high voltage, prevents electric leakage and breakdown, and features high temperature aging resistance for safe long-term operation.
3. Outer XLPO Protective Sheath
- High-strength XLPO outer sheath acts as the outer protective barrier. It resists UV rays, ozone, rain and extreme temperatures, and withstands installation friction and extrusion. LS0H flame-retardant design improves overall fire safety.
4. Integrated Single-Core Overall Structure
- Compact integrated single-core structure balances large current capacity and flexibility. It fits narrow-space wiring, avoids layer peeling, and enhances overall structural stability and service life.
1.Superior Durability
- 25+ year service life at 90°C operating temperature, matching photovoltaic system lifespan
- Wide temperature range: -40°C to +90°C (short-term up to 120°C) for extreme climate adaptation
- Excellent UV, ozone, and hydrolysis resistance for permanent outdoor exposure
2.Enhanced Safety
- Double-layer XLPO insulation: Provides redundant protection against electrical breakdown
- Low-smoke halogen-free (LS0H): Reduces fire propagation and toxic gas emission during combustion (IEC 60332-1, IEC 61034)
- High test voltage: 6500V AC for 5 minutes, ensuring reliable insulation performance
- RoHS compliant: Free from hazardous substances for eco-friendly installations
3.Optimal Performance
- High current capacity: 130-140A at 90°C, suitable for large-scale PV systems
- Low electrical resistance: 0.386 Ω/km at 20°C for minimal power loss
- Excellent flexibility: Class 5 conductor allows bending radius as low as 10× cable diameter
- Chemical resistance: Withstands oils, acids, alkalis, and salt spray for diverse installation environments
4.Easy Installation & Compatibility
- Compatible with all standard PV connectors (MC4, etc.) for seamless system integration
- Lightweight design reduces installation fatigue and transportation costs
- Black sheath color minimizes heat absorption and provides UV protection
