PV Cable

As the core power transmission carrier for solar power systems, PV Cables are custom-developed for harsh outdoor conditions (high radiation, wide temperature fluctuations, corrosive media). They enable safe DC power transmission, resisting UV rays, ozone and humidity. Compliant with international standard TUV 2 PfG 1169/08.2007, they ensure reliable interconnection and stable operation of photovoltaic plants.

I. Core Structural Design: Triple Protection System Adapted to Harsh Outdoor Environments

Layered structural design creates a comprehensive protection system for long-term outdoor reliability. Key features of each layer are as follows:

1. Conductor Layer: Low-Resistance & Flexible for Efficient Transmission & Easy Installation

• Specifications: Class 6 oxygen-free tinned copper (1.5mm²-35mm²), tin plating ≥3μm to prevent copper oxidation and resistance increase.

• Advantages: Multi-strand stranding for flexibility (bending radius ≥4×OD), adapting to PV panel displacement and reducing installation/damage risks.

2. Insulation Layer: Wide-Temperature & Weather-Resistant for Extreme Environments

• Material: Cross-linked polyolefin (XLPO), operating temperature -40℃ to 120℃ (instant 150℃), suitable for extreme temperature fluctuations.

• UV Resistance: ≥3% UV additives, passing 1000-hour UV aging test (strength retention >90%) for long-term outdoor use.

3. Sheath Layer: Double-Layer Co-Extrusion for Protection & Buffering

Double-layer co-extrusion: Inner layer for water blocking & buffering; outer layer for weather resistance & tear resistance, enhancing mechanical and environmental protection.

II. Key Technical Features: Adapted to Long-Term PV System Operation

1. Long Service Life: Matching System Full Life Cycle

Optimized material and structure for long-term outdoor use: Sheath anti-aging agents resist UV, ozone and temperature changes; 25-year service life matching PV modules, reducing replacement and maintenance costs.

2. Stable Transmission: Optimizing System Energy Efficiency

Enhanced electrical performance for DC systems: Stable current-carrying capacity at high temperatures; low-loss design reduces long-distance transmission energy loss; IEC 62930 certified for reliable long-term compatibility with PV connectors.

III. Mainstream Models & Applications: Matching Diverse PV System Needs

• PV1-F: Standard TUV-certified, 1.8kV DC, for distributed rooftop plants, PV greenhouses.

• H1Z2Z2-K: Torsion-resistant (-40℃), designed for tracking PV bracket systems.

• PVY: Armored (galvanized steel strip), rodent/穿刺-proof, for desert/mountain direct burial projects.

• PV-WIRE: Ultra-flexible micro cable (100V DC), for household BIPV concealed installation.
