Cable XLPE Overhead Aluminum SIP-3, SIP-4 12/20 Kv Self-Supporting Protected Insulated Single-Core High-Voltage Wire Sax-W 70 mm​ The Cable XLPE Overhead Aluminum SIP-3, SIP-4 12/20 Kv stands as a high-performance solution for high-voltage power transmission, designed to meet the demands of robust electrical networks. This self-supporting, protected insulated single-core wire, with a 70 mm² conductor cross-section and Sax-W specification, integrates advanced materials and engineering to ensure reliable operation in overhead applications.​ At its core is a 70 mm² aluminum conductor, chosen for its optimal balance of conductivity and lightweight properties. Aluminum’s inherent corrosion resistance, enhanced by a protective coating, ensures durability in outdoor environments, even when exposed to moisture, UV radiation, and industrial pollutants. The conductor is insulated with cross-linked polyethylene (XLPE), a material renowned for its exceptional dielectric strength and thermal stability, enabling safe operation at 12/20 Kv. XLPE insulation resists temperature fluctuations (-40°C to 90°C) and minimizes electrical losses, ensuring efficient power transmission.​ The self-supporting design eliminates the need for additional support structures, featuring a reinforced messenger wire integrated into the cable assembly. This design simplifies installation, reduces clutter on utility poles, and enhances mechanical stability against wind, ice, and vibration. The protected insulation layer adds an extra barrier against physical damage, such as impact from debris or rodents, extending service life in harsh conditions.​ SIP-3 and SIP-4 variants cater to varying load requirements, with the 70 mm² conductor providing ample current-carrying capacity for high-voltage distribution in urban, rural, and industrial settings. Compliant with industry standards for high-voltage cables, this wire is ideal for connecting substations, industrial facilities, and large commercial complexes to the main power grid.​ In summary, the Cable XLPE Overhead Aluminum SIP-3, SIP-4 12/20 Kv combines high-voltage performance, durability, and ease of installation, making it a trusted choice for reliable high-voltage overhead power transmission.
