The BlueStorm BS-DC CABLE-4mm2 is a single-core, halogen-free DC cable built to EN 50618 (H1Z2Z2-K) and IEC 62930 for photovoltaic and DC power connections. It uses a Class 5 stranded tinned-copper conductor with cross-linked polyolefin insulation and sheath, rated 1500 V DC and rated for continuous operation from -40 C to +90 C. The cable is UV- and ozone-resistant for use inside and outside buildings and is supplied in 100 m lengths.
