2XS2Y / N2XS2Y / A2XS2Y / NA2XS2Y Cable Construction

2XS2Y / N2XS2Y / A2XS2Y / NA2XS2Y Cable Application

• 2XS2Y
• Vertical installation in indoor cable trenches or cable shafts.
• Feeder circuits for motors in large factories (especially high-voltage motors).
• A2XS2Y
• Transition sections where overhead lines transition to underground lines (i.e., “overhead-to-underground transition”). In this case, the cable serves only a transmission function, and ground fault currents return via other paths in the system.
• Fixed installation within a factory premises in cable trays or protective conduits, where the system employs high-resistance grounding (fault currents are limited to very low levels).
• N2XS2Y
• Connections between outgoing bays within a substation (from switchgear to transformers).
• Installation in underground utility tunnels or cable trenches in urban core areas (where space is limited and cross-sectional area cannot be increased).
• Locations with extremely high requirements for power supply reliability (e.g., feeder cables for hospitals, data centers, and large shopping malls).
• NA2XS2Y
• Urban ring network power supply (trunk lines from substations to switching stations or prefabricated transformer stations).
• Direct burial beneath sidewalks or green belts.
• TN or IT grounding systems that must withstand large single-phase ground fault currents.

2XS2Y / N2XS2Y / A2XS2Y / NA2XS2Y Cable Standard

• IEC 60502-2 / DIN VDE 0276-620

2XS2Y / N2XS2Y / A2XS2Y / NA2XS2Y Cable Technical Data

2XS2Y / N2XS2Y / A2XS2Y / NA2XS2Y Cable Feature

• Insulation Properties: XLPE (cross-linked polyethylene) insulation with a high temperature rating: long-term operating temperature of 90°C, and up to 250°C during a short circuit (for up to 5 seconds). This significantly outperforms PVC (70°C).
• Water and Moisture Resistance: Features a longitudinal water-blocking structure (semiconductor layer + dense cross-linked XLPE), and the outer sheath is made of PE (polyethylene), resulting in an extremely low water permeability rate, making it suitable for humid environments and direct burial.
• Electric Field Uniformity: The “three-layer co-extrusion” design—inner semiconductive layer + insulation + outer semiconductive layer—eliminates air gaps, effectively uniforming the electric field. Partial discharge is ≤10 pC (as required by IEC 60502), and the service life can exceed 30 years.
• Mechanical Protection: All models feature a lead sleeve or copper tape shielding layer as a radial waterproof barrier; however, they lack steel tape armoring and have only moderate resistance to external mechanical impact (they cannot withstand heavy pressure or direct impact from excavation).
