What is N2XSEFGbY-3 core CU XLPE PVC with SWA Armor?

N2XSEFGbY is a type of power cable that comprises 3 copper cores insulated with XLPE (cross-linked polyethylene) and PVC (polyvinyl chloride) sheathing for protection against environmental factors. Furthermore, the cable is armored with a layer of steel wire armor (SWA) to offer even greater protection. The "SE" in N2XSEFGbY stands for "single extended", which means that the cable has a further extended temperature range of -40°C to +90°C. The "F" stands for fire resistant. "Gb" stands for "Bedding", and "Y" signifies it has a PVC outer sheath. This type of cable is suitable for use in electrical power distribution networks, typically buried underground, as it provides excellent mechanical protection and electrical insulation, as well as resistance to moisture, heat, and corrosion.
