3×70mm² Power Cores: These Aluminum Conductors are the workhorses, responsible for delivering 210A of total current—enough to power 50+ households in a residential complex or a medium-sized industrial facility with machinery and lighting. Each 70mm² core carries 70A, with 61% IACS conductivity ensuring minimal power loss (≤2% over 100 meters). The aluminum’s lightweight properties (40% lighter than copper) reduce stress on poles and simplify handling during installation.
1×54.6mm² Torsade Messenger: This steel-reinforced aluminum strand serves as both structural support and a neutral conductor. With 10kN tensile strength, it eliminates sagging over 80-meter spans, reducing the need for intermediate poles by 50% in new installations. The messenger’s aluminum outer layer adds conductivity, acting as a neutral in unbalanced three-phase systems to stabilize voltage.
2×16mm² Control/Lighting Cores: These Dual Cores enable two-way communication for smart grid integration. One core handles street light dimming signals (cutting 30% off-peak energy use), while the other transmits data from sensors (e.g., power consumption, fault alerts) to central management systems. Their 16mm² cross-section supports 40A current, sufficient for powering auxiliary devices like CCTV cameras or pedestrian crossing lights.
Electrical Properties: With a dielectric strength of 25kV/mm, Vultylene exceeds the 0.6/1kV operating voltage by a factor of 40, providing a robust buffer against voltage spikes from lightning or transformer switching. Its low dielectric loss (<0.002 at 50Hz) minimizes energy waste, a critical factor in long distribution lines.
Thermal Range: The insulation remains flexible from -30°C (subzero winters) to 80°C (summer heatwaves), avoiding the brittleness of PVC in cold or the melting risk of rubber in heat. This ensures consistent performance in regions like northern Europe, the Middle East, and high-altitude areas with extreme temperature swings.
Environmental Resistance: UV stabilizers (3% by weight) prevent degradation from sunlight, a common issue in Overhead Cables that can lead to insulation cracking. Vultylene is also hydrophobic, repelling rain and dew to prevent water ingress—vital for maintaining signal integrity in the 16mm² control cores. In salt spray tests (ASTM B117), it retains 90% of tensile strength after 1,000 hours, outperforming standard EPDM by 20%.
EMI Reduction: The twisted layout causes magnetic fields from the 70mm² power cores to cancel each other out, reducing electromagnetic interference (EMI) by 35%. This is crucial for the 16mm² control cores, which transmit low-voltage signals vulnerable to noise. In field tests, this design reduced signal loss in control lines from 12% (parallel cables) to less than 2%.
Mechanical Stability: Twisting binds the cores into a unified bundle, preventing separation during high winds or installation. This stability minimizes abrasion between cores, extending insulation lifespan by 10+ years compared to unbundled alternatives.
Installation Efficiency: Pre-twisting eliminates the need to twist cores on-site, cutting installation time by 40%. A 3-person crew can deploy 500 meters of cable in a day, versus 300 meters with loose cables. The bundle’s streamlined shape also reduces wind resistance by 25%, lowering stress on utility poles during storms.
Aesthetic Appeal: The neat, twisted bundle reduces visual clutter compared to multiple parallel cables, a key consideration in residential areas or historic districts with strict aesthetic guidelines.
Structural Support: The messenger’s steel-reinforced design (7-strand galvanized steel core wrapped in aluminum) provides 10kN tensile strength, enabling 80-meter spans between poles. This is particularly valuable in rural areas or wide industrial yards, where adding intermediate poles would increase costs by 30%.
Neutral Conductor: The aluminum outer layer conducts electricity, serving as a neutral in three-phase systems. This eliminates the need for a separate neutral core, simplifying the cable’s design and reducing material costs.
Corrosion Resistance: The aluminum cladding protects the steel core from rust, with a 50-year lifespan in coastal environments. In comparison, unprotected steel messengers require replacement every 15-20 years.
Grounding Capability: In emergency situations, the messenger can be used as a grounding conductor, providing a safe path for fault currents to dissipate.
Residential Complexes: The 3×70mm² cores power 50+ homes, while the 16mm² cores control community lighting and security systems. The messenger’s 80-meter spans reduce pole requirements in sprawling developments.
Industrial Parks: Withstands vibration from machinery and chemical exposure, delivering reliable power to factories while using control cores to monitor equipment loads.
Street Lighting Networks: The dual 16mm² cores enable individual lamp dimming and remote fault detection, reducing maintenance patrols by 50%. The messenger supports spans over wide boulevards without sagging.
Smart Grid Pilot Projects: Integrates with IoT sensors to transmit real-time data on power quality and energy use, facilitating demand-response programs that cut peak energy consumption by 15%.
IEC 60502-1: Validates performance in low-voltage Power Cables, including insulation thickness, conductor resistance, and flame retardancy (self-extinguishing per EN 60332-1-2).
ASTM B230: Certifies the aluminum conductors’ conductivity and tensile strength, ensuring consistent current-carrying capacity.
EN 50525-2-21: Specifies requirements for cables in street lighting systems, confirming UV resistance and compatibility with lighting fixtures.
CE Marking: Indicates compliance with EU directives, allowing use in European markets without additional testing.
Visual Inspections: Annual checks for insulation damage (e.g., bird pecks, rodent bites) or loose connections are sufficient for most environments. The smooth Vultylene surface resists debris buildup, reducing cleaning requirements.
Thermal Monitoring: Every 5 years, infrared scans detect hot spots at termination points—an early warning of loose lugs that could cause overheating.
Lifespan: With proper installation, the cable lasts 20+ years, aligning with the typical 25-year lifespan of low-voltage infrastructure. This reduces lifecycle costs, as replacement is needed only once every two decades.
Material Efficiency: Aluminum’s lower embodied energy (5% of copper’s production energy) reduces the carbon footprint by 60% compared to Copper Cables.
Reduced Infrastructure: 80-meter spans cut pole requirements by 50%, preserving green spaces and reducing concrete use.
Energy Savings: Low dielectric loss and smart control capabilities reduce energy waste by 10-15% annually in connected networks.
Lower Installation Costs: Pre-twisting and lightweight design cut labor costs by 40% compared to installing separate power, control, and messenger cables.
