SEU Service Entrance Cable (Aluminum Alloy AA-8000, 600V)
Farwalk’s SEU (Service Entrance Unarmored) cables are the specialized solution for primary residential power entries. Featuring a flat, space-saving oval profile and a concentric neutral conductor, these cables are engineered with high-conductivity AA-8000 series aluminum to deliver safe, cost-effective power from the utility drop to the meter base.
Manufactured in strict accordance with UL Standard 854. The core features phase conductors insulated with heat and moisture-resistant XLPE (Type XHHW-2). A neutral conductor is applied concentrically (helically) over the phase conductors, followed by a binder tape and a sunlight-resistant, lead-free PVC outer jacket. All conductors are premium AA-8000 series aluminum alloy.
Primarily used as a service entrance conductor from the overhead utility power line to the residential or commercial meter base. Its unique flat shape makes it ideal for running along exterior walls where a low profile is aesthetically preferred. Rated for 600 volts and approved for use in both dry and wet locations per the NEC.
• Voltage Rating: 600V
• Conductor: AA-8000 Series Aluminum Alloy
• Insulation: XLPE (XHHW-2 rated)
• Configuration: Flat/Oval with Concentric Neutral
• Outer Jacket: Sunlight-Resistant PVC
• Standard: UL 854
1. Phase Conductors: Class B stranded aluminum alloy (AA-8000 series) or copper.
2. Concentric Neutral: Multiple bare strands of aluminum alloy applied helically over the phase conductors.
3. Insulation: Heat and moisture resistant Cross-linked Polyethylene (XLPE), Type XHHW-2.
4. Reinforcement: A clear or polyester binder tape is applied over the insulated cores.
5. Outer Sheath: Sunlight-resistant, moisture-resistant, and lead-free PVC, typically grey or black.
• Space-Efficient Design: The flat (oval) configuration is specifically designed for thin-profile installations between wall studs and overhead service drops.
• Concentric Neutral Advantage: The neutral conductor is wrapped helically around the phase cores, providing a balanced electrical field and inherent mechanical protection.
• High Environmental Resistance: The XLPE insulation and PVC jacket are optimized for high-UV exposure and wet locations, maintaining a 90°C thermal rating.
• Precise Helical Stranding: We utilize high-speed planetary stranders to ensure the concentric neutral is perfectly uniform, preventing hotspots and ensuring reliable termination.
• UL-Listed Quality: Manufactured to the strict requirements of UL 854, ensuring your project passes all North American and Caribbean residential code inspections.
• Advanced AA-8000 Alloy: Our proprietary aluminum alloy formulation ensures minimal thermal expansion and superior conductivity per pound.
