Ⅰ. Technical Parameters

Ⅱ. Key Features

1. Compact Design for Flexibility

• Ideal for tight spaces in rooftop installations

• 33% smaller cross-section than 4mm² cables

2. High Conductivity

• Low DC resistance (≤7.41Ω/km) minimizes power loss

• Complies with IEC 60228 Class 2 for stranded conductors

3. Weather Resistance

• UV exposure resistance: ≤5% tensile strength loss after 3000 hours

• Hydrolysis resistance: Passes 1000-hour water immersion test

4. Safety Compliant

• Flame retardancy: IEC 60332-1-2 (vertical flame test)

• Halogen-free and low-smoke emission design

Ⅲ. Application Scenarios

Ⅳ. Installation Guidelines

1. Voltage Drop Calculation

• Max recommended run length: 25m for 5kW systems

• Use 4mm² cable for distances >25m

2. Termination

• Compatible with MC4 connectors and ring terminals

• Crimping tool calibration required for optimal connection

3. Environmental Considerations

• Avoid direct contact with sharp edges

• Use conduit in areas prone to physical damage

Ⅴ. Performance Comparison

Ⅵ. Packaging & Availability

• Standard Lengths: 100m, 500m, 1000m reels

• Color Options: Black (negative) / Red (positive)
