Photovoltaic Cable
Key words:
Photovoltaic Cable (PV Cable) is a special cable designed for solar photovoltaic (PV) power generation system, used to connect PV modules, inverters, convergence boxes and power distribution systems. Its core features are ultraviolet (UV), high temperature, acid and alkali corrosion resistance, as well as excellent electrical performance and long-term outdoor durability, suitable for all types of photovoltaic power plants (centralized, distributed, rooftop photovoltaic, etc.).
1. Product structure
| Structural Layer | Material/Characteristics |
|---|---|
| Conductor | -Tin-plated copper: high electrical conductivity, oxidation-resistant (e.g. H1Z2Z2-K). -Copper alloy: used in some high specification models. |
| Insulation | -Cross-linked polyethylene (XLPE) or cross-linked polyolefin (XLPO): high temperature (120°C) and UV-resistant. |
| Sheath | -Non-halogen, low-smoke flame retardant material (LSZH): fire safe, low smoke and non-toxic when burning. -Special weather resistant formula: ozone resistant, acid and alkali resistant. |
| Shielding layer (optional) | Some high voltage models contain copper wire braided shielding, anti-electromagnetic interference (e.g. DC side high current lines). |
2. Product Features
✅Extremely weather resistant
Passed UV aging test (e.g. IEC 62930), can be exposed to outdoor sunlight for more than 25 years without embrittlement.
Adapt to extreme temperature (-40℃~120℃), can be used in high cold or desert area.
✅Excellent electrical performance
DC voltage rating up to 1.5kV (e.g. PV1-F 1.5mm²), reducing transmission loss.
Low insulation resistance (≥1000MΩ-km), resistant to high voltage breakdown.
✅Safe and environmentally friendly
Halogen-free, does not release toxic gases when burning (in accordance with IEC 60754).
Flame retardant grade (IEC 60332), retarding the spread of fire.
✅Mechanical durability
Resistant to twisting and abrasion, suitable for frequent movement of tracking PV mounts.
Flexible, easy to lay and thread pipes.
✅Wide compatibility
Comply with TÜV, UL, CE and other international certifications, suitable for global mainstream PV equipment.
3. Main models and specifications
| Model | Standard | Voltage Rating | Applicable Scenario |
|---|---|---|---|
| PV1-F | TÜV 2PfG 1169 | DC 1.8kV | Series connection between modules, DC side connection |
| H1Z2Z2-K | IEC 62930 | DC 1.5kV | Mainstream models for the European market |
| PV-Wire | UL 4703 | DC 1kV/2kV | North American market, high temperature resistance 125°C |
| PV-CY | Shielded | DC 1kV | Power stations with high anti-interference requirements |
Commonly used cross-sectional area:
DC side: 2.5 mm², 4 mm², 6 mm², 10 mm²
AC side: 16mm², 25mm² (inverter output)
4. Technical parameters
Rated voltage: DC 0.6/1kV, 1.5kV, 1.8kV (some models support 2kV).
Operating temperature: -40℃~+120℃ (short time withstand 150℃).
Conductor resistance: Conforms to IEC 60228 Class 5 (tinned copper).
Withstand voltage test: AC 6.5kV/5min (1.8kV cable).
Bending radius: ≥4 times the outer diameter of the cable.
5. Field of application
Connection between PV modules: DC output of series/parallel modules.
DC convergence box to inverter: high current transmission.
Inverter to grid: AC side output (need to cooperate with AC cable).
Building Integrated Photovoltaic (BIPV): Roof and curtain wall hidden wiring.
Floating photovoltaic power station: moisture-resistant and hydrolysis-resistant design.
6. Laying and installation
Outdoor direct laying: no need to penetrate the pipe, UV-resistant sheath can be directly exposed.
Pipe-through/bridge: protection is recommended in areas with high risk of mechanical damage.
Fixing method: Use PV-specific wire clips to avoid metal scratches.
Precautions:
Avoid contact with sharp edges.
DC positive and negative cables need to be laid separately to prevent short circuits.
