YJLV22 26/35kV Medium Voltage Aluminum Alloy Armored Power Cable
- Conductor: High-strength aluminum alloy, round, tightly stranded conductor
- 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 provides strong mechanical protection.
- Outer sheath: Polyvinyl chloride (PVC), polyethylene (PE), or halogen-free low-smoke polyolefin (WD)
Application
This YJLV22 26/35kV aluminum alloy medium-voltage armored power cable is an economical solution for building medium-voltage power distribution networks and achieving efficient power transmission. The aluminum alloy conductor ensures reliable conductivity while significantly reducing cable weight (approximately 30%-40% lighter than copper cables of the same specification), substantially reducing transportation, installation, and support costs. It is particularly suitable for long-distance power transmission and fixed installation of large-section trunk lines.
Cable armored structures offer superior protection against pressure and impact, making them suitable for harsh environments requiring high mechanical strength, such as direct burial, cable trenches, tunnels, pipe corridors, and bridges. They are primarily used in main power distribution in industrial parks, urban power grid upgrades, voltage boosting for new energy power plants, and high-voltage power supply for large commercial complexes.
