Single-core photovoltaic cable Helukabel SOLARHELU 1x6 mm² 1500 V DC red H1Z2Z2-K (MPN 18048772)

Helukabel SOLARHELU single-core photovoltaic cable 1x6 mm² is a red, H1Z2Z2-K constructed DC cable rated for 1500 V DC. It is designed for string connections and rooftop solar installations where reliable DC power transmission and resistance to outdoor conditions are required. The cable combines a 6 mm² conductor cross-section with insulation and outer sheath materials formulated for UV exposure and long-term outdoor use.

Advantages

The SOLARHELU cable provides a balance of electrical capacity and mechanical flexibility suitable for PV system interconnections. Its H1Z2Z2-K construction ensures enhanced resistance to UV radiation and ozone, and the cable is suitable for fixed installation in open air and on rooftops. The red color enables straightforward polarity identification during installation and maintenance, reducing wiring errors. The 1500 V DC rating allows use in modern high-voltage PV arrays.

Suitable for

• Module-to-module string connections in photovoltaic arrays
• DC cabling from PV strings to combiner boxes or inverters
• Rooftop and ground-mounted PV installations requiring UV-resistant cabling
• Outdoor fixed installations exposed to sunlight and weathering

Key specifications

• Conductor cross-section: 6 mm²
• Number of cores: single-core (1x)
• Rated voltage: 1500 V DC
• Insulation and sheath type: H1Z2Z2-K (UV and ozone resistant formulation)
• Color: red
• Application environment: outdoor, rooftop, open air

How to use

Use the cable for DC power connections within photovoltaic systems, connecting solar modules, strings, combiner boxes and inverters as required by the system design. Ensure correct polarity by following the red conductor marking and verify that the cable routing avoids sharp edges, excessive bending, and mechanical strain. Installations should observe local electrical codes and safety standards for PV systems; use appropriate glands, connectors and strain relief to maintain the cable's protection against weather and mechanical damage.

Usage recommendations

For long service life, route the cable to minimize exposure to mechanical abrasion and avoid contact with hot surfaces. Use connectors and junction boxes rated for 1500 V DC and compatible with H1Z2Z2-K cables. Perform visual inspections periodically to check for sheath damage and secure fixing points, and follow manufacturer and local regulations for PV installation and earthing.
