In the European and American renewable energy markets, 50kW photovoltaic power stations are becoming a popular choice for commercial buildings and small to medium-sized farms. While these projects are moderate in scale and offer stable investment returns, their successful operation relies on a key component—the cable system. As the "energy blood vessels" of PV power stations, cable selection directly impacts the system's power generation efficiency, safety performance, and service life.
Lianke Company has years of experience in the European and American photovoltaic markets, with a deep understanding of stringent safety certifications, environmental standards, and grid regulations. Our cable solutions strictly comply with EU EN standards and U.S. UL specifications, providing customers with one-stop cable selection services that balance compliance with efficient and safe operation.
Lianke DC photovoltaic cables strictly pass UL4703 (North America) or EN50618 (EU) certifications, perfectly adapting to 1500VDC high-voltage system architectures. We recommend using 1×4mm² (12AWG) or 1×6mm² (10AWG) copper-core cables, with H1Z2Z2-K double-jacketed models prioritized for the EU market.
Unique advantages of Lianke cables:
Temperature resistance rating up to 125°C, capable of withstanding extreme temperature differences from -40°C to 150°C
Passes stringent UV aging and salt spray corrosion tests
Complies with EU RoHS and REACH environmental directives
Lianke provides customized AC cable solutions for different grid standards in Europe and America:
European market: YJV22-0.6/1kV 4×25mm²+1×16mm² copper-core cables, perfectly matching 400V three-phase grids
North American market: RHW-2 type 25mm² copper cables or AA8000 series alloy aluminum cables, adapted to 480V three-phase grids
Our engineering team precisely calculates voltage drop to ensure strict standards of ≤2% on the DC side and ≤3% on the AC side, guaranteeing power generation efficiency.
Based on a deep understanding of European and American markets, Lianke offers differentiated cable selection recommendations:
Copper cables: Use Class 2 conductors compliant with UL44 or EN 60228 standards, especially suitable for high-reliability projects in Europe and coastal areas of North America, leveraging their advantages of high conductivity and strong corrosion resistance.
Aluminum cables: Strictly select AA8000 series alloy conductors certified to ASTM B801, providing cost-effective solutions for inland projects in North America and budget-sensitive projects, with costs 30% lower than copper cables and lighter weight for easier long-distance installation.
Lianke professional recommendation: Prioritize copper cables in the European market; aluminum cables can be used on the AC side in North America after strict voltage drop verification, but should be avoided in coastal salt spray environments.
The selection of insulation materials reflects Lianke's technical expertise:
DC side: Uses cross-linked polyethylene (XLPE) or EP rubber insulation, combined with halogen-free low-smoke flame-retardant jackets
AC side: Flexibly provides XLPE insulation (heat-resistant, suitable for underground installation) or PVC insulation (cost-optimized, suitable for dry environments) based on application scenarios
All Lianke cables pass the most stringent certification tests:
North American market: Passes VW-1 vertical flame test, with flame resistance rating reaching UL94 V-0 level
EU market: Fully marked with CE certification and usage temperature range
Lianke not only provides high-quality cable products but also offers complete installation solutions:
Installation guidance: Advocates for underground installation methods, providing professional cable trench or protective conduit installation solutions, ensuring DC and AC cables are installed separately with a spacing of ≥30cm
Protection design: Provides specialized protection for different environments
Outdoor installation: Added rodent-proof protective jackets
European Alpine regions: Special anti-freezing crack designs
North American hurricane zones: Enhanced tensile strength structures
Grounding system: Strictly complies with IEC 60364-7-712 (EU) or NEC grounding requirements, provides ≥4mm² yellow-green dual-color copper cables for component frame and bracket grounding, ensuring grounding resistance ≤0.1Ω
Choosing Lianke cables provides you with:
Certification assurance: Full range of products pass necessary certifications such as UL, TÜV, and CE, ensuring smooth grid connection approval
Precise specifications: Accurate matching of 4-6mm² certified photovoltaic cables for the DC side, and 25-35mm² copper or 35mm² aluminum cables for the AC side
Detail control: Full-process professional support from insulation material selection to installation and grounding guidance
Lianke Company deeply understands that in the European and American photovoltaic markets, cables are not just simple connection components but critical elements related to system safety, efficiency, and compliance. Let us use our professional technology and extensive experience to provide the most reliable "energy blood vessel" solutions for your 50kW photovoltaic power station.
