Product Identification

Note: The technically correct material abbreviation is XLPO (cross-linked polyolefin), not “XPLO.”

Product Title

JOCA 4mm² H1Z2Z2-K XLPO Solar DC Cable

Short Description

JOCA 4mm² single-core photovoltaic cable is designed for 1500V DC solar installations. It uses a flexible Class 5 tinned-copper conductor with halogen-free, electron-beam cross-linked XLPO insulation and outer sheath. The cable is available in red and black and is specified for rooftop, ground-mounted and floating PV applications.

Long Description

The JOCA 4mm² solar cable is a purpose-built photovoltaic conductor for dependable DC connections between solar modules, string equipment and inverters. Its 1 × 4.0mm² Class 5 tinned-copper conductor combines flexibility with corrosion resistance, while the double XLPO construction provides robust electrical insulation and environmental protection.

JOCA specifies this cable for up to 1500V DC and lists compliance with IEC 62930 and EN 50618. The manufacturer also publishes resistance to UV, ozone and hydrolysis, a working-temperature range of -40°C to +90°C, and an expected service life of at least 25 years. Red and black sheath options support clear DC polarity identification during professional solar installation.

Final cable sizing, ampacity, connector compatibility, routing and derating must be confirmed by a qualified solar installer according to the project design and applicable electrical codes.
