12/20 (24)kV NA2XS2Y Cable Feature
- High Operational Reliability: Its core insulation structure consists of a conductor shield, an XLPE insulation layer, and an insulation shield; these three layers are co-extruded and permanently bonded together. This design completely eliminates interlayer air gaps, effectively suppressing partial discharge and thereby achieving extremely high operational reliability.
- Weather Resistance and Water Resistance: The outer sheath is made of MDPE (medium-density polyethylene) and features UV resistance, making it ideal for outdoor, direct burial, or conduit installation. The cable is designed with two longitudinal water-blocking layers, making it suitable for high-humidity environments and even underwater applications.
- High Mechanical Strength: The PE outer sheath can withstand high mechanical stresses during installation. Its minimum bending radius is 15 times the cable’s outer diameter, which must be observed during installation.
