NA2XS(F)2Y 1x240/25 12/20kV电缆
安徽飞纯特种电缆有限公司The cable designation NA2XS(F)2Y 1x240/25 12/20kV follows a standardized naming convention for medium voltage power cables. Here's a breakdown of its components:
1. Cable Type: NA2XS(F)2Y
NA: Indicates a single core, unarmored cable.
2X: Cross linked polyethylene (XLPE) insulation.
S: Copper wire screen (concentric neutral).
(F): Longitudinal water barrier (optional, often using swellable tapes or aluminum laminate).
2Y: Polyethylene (PE) outer sheath (resistant to moisture and chemicals).
2. Conductor Size: 1x240/25
1x240: Single core cable with a 240 mm² copper conductor.
/25: The neutral/screen has a 25 mm² cross sectional area (often used for grounding/earthing).
3. Voltage Rating: 12/20 kV
12/20 kV: Rated for 12 kV phase to phase voltage and 20 kV phase to-ground voltage (common in medium voltage distribution).
Key Features:
Insulation: XLPE (excellent thermal and electrical properties).
Shielding: Copper screen for uniform electric field and fault current dissipation.
Sheath: PE for mechanical and environmental protection.
Application: Underground or duct installations in medium voltage networks (e.g., industrial plants, substations).
Comparison with Similar Cables:
NA2XS2Y: No longitudinal water barrier.
NA2XS(F)2Y: Includes water blocking layer (better for wet conditions).
NA2XSY: Different sheath material (e.g., PVC instead of PE).
