2XS(F)2Y / N2XS(F)2Y / A2XS(F)2Y / NA2XS(F)2Y Feature

• Insulation System: Utilizes a three-layer co-extrusion process (inner semiconductive layer + XLPE main insulation + outer semiconductive layer), dry cross-linking, low partial discharge level (≤5 pC), high electrical strength, and a design life of ≥30 years.
• Metal Shielding Structure: Copper wires are concentrically wound to form the primary shield, with an additional layer of 0.1 mm thick copper tape overlapping and covering the shield. The copper wires carry steady-state induced currents and short-circuit fault currents, while the copper tape serves the dual purpose of securing the copper wires and providing auxiliary short-circuit capacity.
• Longitudinal Water-Barrier Design: Features a dual-layer water-barrier system. The first layer consists of a wrapped semiconductive water-barrier tape; the second layer can be either a water-barrier insulating tape (Type I) or a combination of water-barrier powder and plastic tape (Type II). Upon contact with water, the water-barrier material expands to seal gaps, preventing moisture migration along the cable’s longitudinal axis.
• Outer Sheath Material: A PE (polyethylene) sheath is used, which has an extremely low water vapor permeability (approximately 1/10 that of PVC), is resistant to low temperatures (-40°C), and is resistant to chemical corrosion from acids and alkalis, making it suitable for humid and underground environments.
• Fire Safety Limitations: The PE sheath is not flame-retardant; it will continue to burn and produce dripping when exposed to fire. Direct use is strictly prohibited in locations with fire safety requirements, such as indoor substations and underground passageways with high pedestrian traffic.
