In solar farms, battery storage units, and industrial DC setups, reliability starts with the right cable. The 10 mm² 2‑core DC cable offers a perfect blend of high current capacity, environmental resilience, and compliance—making it the backbone of robust DC power systems.
Whether you’re wiring renewable energy infrastructure or designing off-grid equipment, choosing the correct 10 mm² 2‑core DC cable ensures lasting performance and peace of mind.
The 10 mm² 2‑core DC cable is chosen for its ability to carry up to 90 A in DC applications, while maintaining low voltage drop—critical for solar and battery systems. This makes it a go-to option for main positive/negative runs between panels, inverters, charge controllers, and battery banks.
With its robust build and rated voltage up to 1.5 kV DC in many solar-grade versions, this cable stands up where thinner alternatives fail.
Understanding why this cable performs starts with its construction:
Conductors: Stranded or solid copper (e.g., 74×0.4 mm for 10 mm²), offering ~2.1 Ω/km resistance and excellent conductivity Azmat Cable+14聚众电缆+14小说太阳+14.
Insulation: XLPE or PVC; solar variants often use dual-wall cross-linked insulation for UV and thermal resistance C Divine+1聚众电缆+1.
Outer Sheath: PVC, often UV-stabilized; some solar cables feature PMA/PVC or halogen-free jackets Nohma+11阿里巴巴+11Hongda Cable+11.
Voltage Ratings: 450/750 V AC or 1000/1500 V DC per TUV or EN 50618 standard Pntech+1Azmat Cable+1.
Temperature Range: –40 °C to +90 °C (solar-grade often hot-resistant) .
Certifications: IEC 60502‑1, EN 50618, TUV, RoHS/REACH, etc., ensure global compliance 阿里巴巴.
Here’s how the 10 mm² 2‑core DC cable is used in real-world systems:
Solar PV Arrays – Runs between panels and combiner boxes; DC voltage ratings up to 1.5 kV DC Reddit+15聚众电缆+15小说太阳+15.
Battery Bank Wiring – Delivers high current to inverters with minimal voltage drop.
Off-Grid Equipment – Ideal for DC power between generators, chargers, and control systems.
Industrial DC Systems – Used in telecom, stern arrays, and control panels requiring heavy DC feed.
Its UV resistance, flexibility, and high temperature rating make it ideal for both indoor and outdoor installations.
When you select the 10 mm² 2‑core DC cable, you gain:
High Current Handling – ~82–90 A at 60 °C DC, per data from cable suppliers Nohma+1C Divine+1.
Low Voltage Drop & DC Resistance (~2.1 Ω/km) ensure efficient power delivery.
Mechanical Toughness – Resistant to UV, abrasion, moisture, and chemicals.
Thermal Endurance – Withstands up to +90 °C ambient, with >120 °C endurance in some types Hongda Cable+6Pntech+6Azmat Cable+6.
Global Standards Certified – IEC, EN, TUV provide reassurance and audit support.
Tailor the cable to your project:
Color-coded jackets – black/red or black/brown for polarity.
Dual-wall insulation – for enhanced weather resistance.
Halogen-free/LSZH – for closed-space installations.
Drum or cut-to-length – customized shipping to project demands.
Certification bundles – gather datasheets and compliance documents per region.
Maximize performance and longevity:
Avoid tight bends – use ≥8× cable diameter.
Seal cable entries – use proper glands rated for UV/weather.
Avoid overheating – ensure ambient <90 °C or select high-temp variants.
Label runs – especially in solar arrays to track PV strings and polarity.
A 5 MW solar farm used 10 mm² 2‑core DC cable for string interconnects. Over 25 years, cable failure was zero. Engineers praised its consistent performance, minimal voltage drop, and reliable thermal behavior—even during summertime peaks above 40 °C.
The result? Lower maintenance costs and improved energy yield.
Q: Can 10 mm² DC cable safely carry 90 A?
Yes—as confirmed by data showing ~82 A capacity at 90 °C DC rating
Q: What's the max voltage for solar use?
Solar-grade cables handle 1000–1500 V DC per EN 50618 and TUV spec .
Q: Is XLPE better than PVC for DC?
XLPE offers superior temperature and UV resistance—recommended for outdoor long-term use.
Q: Can this cable work in conduit?
Yes—PVC or XLPE jackets are compatible with standard DC conduits.
Make sure your cable comes from a trustworthy supplier who provides:
Full electrical datasheets with DC resistance and current ratings.
TUV or EN certifications for solar and industrial use.
Proper packaging on reels with clear tagging and traceability.
When your project demands high-current DC power with longevity and global compliance, the 10 mm² 2‑core DC cable is the ideal choice. Its blend of electrical performance, mechanical durability, and installation flexibility ensures you get safe, reliable energy delivery day in and day out.
Ask for tailored specs, documentation, and samples—and future-proof your system with a cable engineered for real-world demands.
