Solar Energy Cable Single Core 4mm² Red XLPE AD7 - 25m Reel

Product Overview

The Solar Cable SOLAR1X4RDR25/AD7 is a 25 m Reel of 4 mm² single-core solar energy cable in red, designed for robust DC wiring in photovoltaic (PV) systems and related fixed electrical installations. This cable uses a flexible tinned copper conductor with cross-linked polyethylene (XLPE) insulation and sheath to deliver trustworthy performance in both internal and external cabling environments. It meets the harmonised H1Z2Z2-K solar standard and complies with BS EN 50618, rendering it suitable for PV array interconnections, junction box wiring and connections to inverters or controllers. The XLPE construction provides excellent resistance to UV, ozone, moisture and temperature variation, helping preserve performance in rooftop and outdoor conditions. Halogen-free and flame-retardant properties improve safety in both residential and commercial solar cabling applications. Rated for 600 V-1000 V AC and up to 1800 V DC, this cable supports dependable energy transmission across a range of solar PV system requirements. The 25 m Reel offers an installer-friendly length for shorter DC cable runs between panels, junctions or equipment in renewable energy installations, lessening the need for additional joins and speeding up on-site work.
