8.7/15kV 3×240mm² Aluminum Alloy Medium-Voltage Armored Power Cable
- Conductor: High-strength aluminum alloy, round tightly stranded conductor, 240mm² × 3 cores
- Conductor shielding (inner shielding layer): Extruded cross-linked semi-conductive material (standard structural layer for medium-voltage cables)
- Main insulation layer: Cross-linked polyethylene (XLPE), the core of the cable's electrical insulation.
- Insulation shielding (outer shielding layer): Extruded cross-linked semiconductive material
- Metallic shielding layer: Copper or aluminum alloy strip shielding
- Filler layer: Non-hygroscopic material (such as polypropylene rope)
- Wrapping layer: Non-moisture-absorbing tape
- Inner sheath (isolation sleeve): Polyethylene (PE) or Polyvinyl chloride (PVC)
- Armor layer: Galvanized steel strip armor (steel strip can be used for three-core structures), providing mechanical protection.
- Outer sheath: Polyvinyl chloride (PVC), polyethylene (PE), or halogen-free low-smoke polyolefin (WD)
Application
This 8.7/15kV 3×240mm² aluminum alloy medium-voltage armored power cable is suitable for 8.7/15kV voltage level transmission and distribution circuits in urban power distribution networks, industrial parks, commercial centers, and new energy power generation projects. The aluminum alloy conductor ensures conductivity while significantly reducing cable weight (approximately 50% of that of a copper cable of the same specification), substantially reducing transportation and installation costs, making it particularly suitable for long-distance, large-span fixed installations.
The cable armor structure enhances its resistance to pressure and impact, making it suitable for various laying environments such as direct burial, cable trenches, tunnels, and pipelines, and meeting stringent mechanical protection requirements.
