The Single Core Overhead Insulated Cable (SAC) is a specialized medium-voltage solution designed for the primary distribution of electricity in overhead networks. Operating at voltage levels from 11kV to 35kV, this cable provides a safe and reliable alternative to traditional bare conductors in medium-voltage applications. The fully insulated design significantly enhances network reliability and safety, making it an ideal choice for areas with high environmental exposure or in urban environments where clearance is a concern. Our SAC cables are engineered to meet the rigorous demands of modern power grids in rapidly developing regions.
Product Construction
The SAC cable features a compacted stranded aluminum conductor, extruded conductor screen, a high-performance XLPE insulation layer, (optional insulation screen, and a metallic screen), the outermost layer is a rugged and UV-resistant PE outer sheath, protecting the cable from environmental factors. This construction ensures the cable can withstand the mechanical and environmental stresses of overhead installation, including UV exposure, temperature extremes, and wind loading.
Typical Applications
Medium-voltage (MV) primary overhead distribution networks
Rural and urban electrification projects
Substation feeder lines and interconnections
Industrial power distribution systems
Areas with high levels of airborne pollution or salt spray
Manufacturing Standards & Voltage
Standards: IEC 60502-2, ICEA S121-733, BS EN 50397, ABNT NBR11873, NTC5909
Voltage Ratings: Available in 10kV, 15kV, 20kV, 25KV and 30kV to suit a wide range of network voltages.
