Medium Voltage Power Cable
High-performance Medium Voltage (MV) Power Cables engineered for safe, high-capacity energy transmission in primary distribution networks. Rated from 3.6/6 kV up to 18/30 kV, featuring triple-extruded XLPE insulation, metallic screening, and robust SWA/STA/AWA armouring to ensure ultimate reliability in harsh environments.
Farwalk’s Medium Voltage (MV) Power Cables are the critical arteries of modern power grids and heavy industrial facilities. Manufactured using an advanced dry-cured catenary continuous vulcanization (CCV) process, our MV cables guarantee zero partial discharge and exceptional dielectric strength. Whether for underground direct burial, substation integration, or renewable energy collection networks, these cables provide decades of uninterrupted service.
• Utility & Power Grids: Primary underground distribution networks and substation step-down connections.
• Heavy Industry: Main feeders for oil & gas refineries, mining operations, and steel mills.
• Renewable Energy: MV collection circuits for solar PV farms and onshore/offshore wind turbines.
• Infrastructure: Power supply for railway electrification systems, large data centers, and tunnel networks.
• International: IEC 60502-2, IEC 60228, IEC 60332-1-2
• British Standards: BS 6622 (PVC), BS 7835 (LSZH)
• National Standards: GB/T 12706.2 (YJV22, YJV32)
• German/European: VDE 0276-620
*Note: Custom compliance for AS/NZS or IEEE available upon project request.*
1. Conductor: Class 2 stranded plain Copper (Cu) or Aluminum (Al).
2. Conductor Screen: Extruded semi-conductive compound.
3. Insulation: High-purity XLPE (Cross-linked Polyethylene), rated for 90°C.
4. Insulation Screen: Extruded semi-conductive compound, firmly bonded to the insulation.
5. Metallic Screen: Copper tape (CTS) or Copper wire screen (CWS) to handle earth fault currents.
6. Inner Covering: Extruded PVC or LSZH.
7. Armour:
– Single Core: AWA (Aluminum Wire Armour) to prevent magnetic induction heating.
– Three Core: SWA (Galvanized Steel Wire) or STA (Galvanized Steel Tape).
8. Outer Sheath: Heavy-duty PVC, UV-resistant PE, or fire-retardant LSZH.
• Exceptional Dielectric Integrity: Triple-extrusion technology minimizes electrical stress and prevents water treeing.
• High Fault Tolerance: Sustains short-circuit temperatures up to 250°C for 5 seconds.
• Superior Mechanical Defense: Heavy armouring protects against extreme crush loads, tensile stress, and rodent damage.
• Custom Earth Fault Capacity: Copper screen cross-sections can be customized to match specific network short-circuit requirements.
• Ultra-Clean Material Handling: We use fully enclosed material feeding systems to ensure XLPE purity, critical for MV cable lifespan.
• 100% Partial Discharge Testing: Every single drum undergoes rigorous PD and high-voltage testing in our Faraday cage laboratory before dispatch.
• Full-Matrix Specifications: We cover the entire MV spectrum (6kV, 11kV, 15kV, 22kV, 33kV) with customized armour and sheath solutions.
• Engineering Support: We provide complete technical datasheets, dimension drawings, and installation radius calculations within 24 hours.
Comparison Logic
| Armour Type | Cable Structure | Magnetic Induction | Primary Application Scenario |
| AWA (Aluminum Wire) | Single Core (1C) | Non-magnetic (Prevents overheating) | High power capacity, easy termination routing |
| SWA (Steel Wire) | Three Core (3C) | Magnetic (Canceled by 3-phase field) | Direct burial, high tensile strength (pulling) |
| STA (Steel Tape) | Three Core (3C) | Magnetic (Canceled by 3-phase field) | Direct burial, excellent crush resistance |
