PV1-F Cable is a halogen-free, UV-resistant photovoltaic cable designed for DC wiring in solar power systems. This guide covers key specifications, certification standards, and choice criteria from singielectric.
PV1-F Cable is a single-core, halogen-free photovoltaic cable rated for DC volt-levels up to 1.5 kV. It features tinned copper conductors, cross-linked polyethylene (XLPE) insulation, and a UV-stable, flame-retardant sheath. The cable is designed for outdoor installation in solar photovoltaic systems, connecting solar panels to inverters and combiner boxes. It withstands extreme temperatures from -40°C to +90°C (120°C in short circuit) and offers high resistance to ozone, moisture, and mechanical stress.
Solar PV systems operate under constant sunlight and temperature variations. Standard PVC cables degrade under UV exposure, leading to insulation cracking, short circuits, and system failures. PV1-F Cable is engineered to endure harsh outdoor environments for 25+ years, matching the lifespan of solar modules. Its halogen-free composition reduces toxic smoke in case of fire, meeting safety requirements for rooftop installations. Using certified PV1-F Cable ensures compliance with international standards and reduces maintenance costs.
| Property | PV1-F Cable | Standard PVC Cable |
|---|---|---|
| Volt-level Rating | DC 1.5 kV | AC 0.6/1 kV |
| Insulation | XLPE (cross-linked polyethylene) | PVC |
| UV Resistance | Excellent (EN 50618 tested) | Poor (degrades ) |
| Temperature Range | -40°C to +90°C | -15°C to +70°C |
| Halogen-Free | Yes (low smoke, non-toxic) | No (emits toxic HCl when burned) |
| Lifespan | >25 years | <10 years outdoors |
PV1-F Cable is purpose-built for solar applications, while standard cables lack the environmental resistance required for long-term outdoor use.
A reliable PV1-F Cable must comply with:
Products from singielectric carry these certifications, guaranteeing performance and safety.
Note: While PV1-F remains common, newer designs like H1Z2Z2-K (per IEC 62930) offer identical performance. Always verify the cable supports your system volt-level ( DC 1500V).
Consider these factors when choosing PV1-F Cable:
PV1-F is optimized for DC applications. While it can carry AC volt-level, its certification focuses on DC solar systems. Use dedicated AC cables for grid connections.
5 times the outer diameter for fixed installations. Check manufacturer datasheet for exact values.
Standard PV1-F does not have rodent protection. In areas with high rodent activity, use armored versions or conduit.
Properly installed and certified PV1-F cable has a service life exceeding 25 years under normal outdoor conditions.
