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

Product Overview

The Solar Cable SOLAR1X4BKR25/AD7 is a 25-metre reel of high-quality single-core 4 mm² cable designed for solar photovoltaic (PV) installations needing robust DC cabling. Manufactured with a flexible, tinned copper conductor and XLPE (cross-linked polyethylene) insulation and sheath, this cable is suitable for both internal and external fixed wiring in solar panel arrays or related equipment. It complies with BS EN 50618 and carries the harmonised H1Z2Z2-K standard for solar energy cables, ensuring dependable performance in PV systems. The cable’s construction provides halogen-free properties, flame retardancy, and resistance to ozone plus UV exposure, making it suitable for use in varying weather conditions on rooftops, in conduits, or on cable trays. Rated for high DC voltages up to 1800 V DC and AC voltages from 600 V to 1000 V, this cable supports reliable energy transmission from solar panels to inverters and controllers. This 25m reel length is ideal for shorter runs within solar PV arrays, battery connections, or DC cabling from modules to junction boxes. The cable's compact, flexible nature supports straightforward installation and routing in tight spaces.
