RZ1-K 0.6/1kV Cable is a type of photovoltaic solar cable, a flexible, low-smoke, halogen-free, low-voltage power cable. It is specifically designed for fixed installations and operates at 0.6/1kV. Manufactured in accordance with Spanish standard UNE 21123-4, this cable is widely used in buildings, public facilities, and industrial power distribution systems with high fire-resistance requirements. RZ1-K cable uses a Class 5 flexible copper conductor and an LSZH insulation sheath, exhibiting excellent flame retardancy, low smoke emissions, and ease of installation in confined spaces.
