Product Description

Product overview

The 4mm² Solar Cable EN 50618 certified is specifically designed for use in photovoltaic (PV) systems for interconnecting solar panels and electrical components. It ensures long-term durability and optimal electrical performance under harsh outdoor conditions, including UV radiation, ozone, and extreme temperatures. The cable is insulated and sheathed with halogen-free, cross-linked polymer (LSZH), ensuring enhanced fire resistance and minimal toxic fume emission.

Certified under the EN 50618 standard, this cable is suitable for fixed installation both indoors and outdoors, in open air, ducts, conduits, or buried (with protection). It's widely adopted in solar farms, residential and commercial rooftop systems, and off-grid installations.
