Common models of photovoltaic DC cables mainly include PV1-F and H1Z2Z2-K. These two types are currently the most widely used dedicated DC cables in global photovoltaic systems.
1. PV1-F Model
Applicable Standards: Complies with international certification standards such as TÜV 2PfG 1169/08.2007.
Voltage Rating: Suitable for DC 1.8kV and below systems, commonly used in distributed rooftop and commercial/industrial photovoltaic projects.
Conductor Material: Uses tin-plated copper wire to improve oxidation resistance and conductivity stability.
Insulation and Sheath: Uses irradiated cross-linked polyolefin (XLPO), possessing excellent weather resistance, high and low temperature resistance (-40℃~+125℃), UV resistance, and flame retardant properties.
Example: PV1-F 1×4mm² is a mainstream specification, widely used for module series connection and combiner box connection.
2. Model H1Z2Z2-K
Applicable Standards: Designed according to European standard EN50618-2014, optimized for high-voltage systems.
Voltage Rating: Supports DC 1500V systems, suitable for large ground-mounted substations or high-voltage grid-connected projects.
Conductor Structure: Uses IEC60228 standard Category 5 tin-plated copper conductors, flexible and easy to bend.
Sheath Colors: Black (negative) and red (positive) for easy polarity identification and reduced wiring errors.
Mechanical Properties: High tensile strength and abrasion resistance, suitable for long-distance laying and harsh environments.
