Our CAI Copper Aerial Distribution Cables are self-supporting, insulated cables designed for urban and rural overhead secondary distribution networks with voltages up to 1000V. Featuring a covered neutral but without integrated public lighting conductors, these cables offer a robust and efficient solution for power delivery in various environments.
Key Features & Benefits
- Self-Supporting Design: Permits longer spans, lower mounting heights, and requires minimum support structures, simplifying installation, especially in areas with trees or congestion.
- Enhanced Safety: Provides maximum personnel safety and protection against power outages due to its insulated construction.
- Durability: Offers excellent resistance to abrasion, flexing, heat, moisture, UV sunlight, and cold, ensuring high dependability and long service life.
- Versatile Core Configuration: Available in 2 to 5 cores to meet various network requirements.
- High-Quality Materials: Utilizes stranded round copper conductors and XLPE insulation for superior electrical performance and longevity.
Applications
CAI Self-Supporting Cables are primarily used for:
- Urban and Rural Overhead Secondary Distribution Networks: Ideal for delivering power to homes and businesses in both city and countryside settings.
- Congested Areas: Their self-supporting nature and compact design make them highly suitable for installation in areas with limited space or obstructions like trees.
Standards Compliance
Our CAI Self-Supporting Cables are manufactured and tested to comply with or exceed the following standards:
- NTP-IEC 60228: Conductors of insulated cables.
- NTP 370.254: Cables for overhead distribution networks self-supporting XLPE insulated of rated voltages up to and including 0.6/1 kV.
- NTP 370.251: Copper cables for overhead (bare or protected) and grounded.
Construction Details
The cable's robust construction ensures reliable and long-lasting performance:
- Phase Conductor: Hard drawn copper conductor, Class 2 stranded, providing excellent conductivity.
- Neutral Messenger Conductor: Hard drawn copper conductor, Class 2 stranded, acting as both a neutral and self-supporting element.
- Insulation: All conductors are insulated with Cross-Linked Polyethylene (XLPE), offering superior electrical insulation and resistance to environmental factors.
