12/20kV Aluminium Conductor XLPE Insulation Steel-free Twisted Cable for Overhead Lines

Application

The 12/20kV Aluminium Conductor XLPE Insulated Steel-Free Twisted Cable is designed for medium voltage overhead power distribution systems, offering a lightweight and reliable solution for modern electrical networks.

This cable is widely used in overhead transmission and distribution lines, particularly in urban, suburban, and rural electrification projects where reduced weight and ease of installation are important. The steel-free twisted design eliminates the need for steel reinforcement, making the cable lighter, easier to handle, and more suitable for long-span installations.

With XLPE insulation, the cable provides excellent electrical performance and thermal stability, allowing for higher current carrying capacity and reliable operation under varying load conditions. It is especially suitable for areas where corrosion resistance is required, such as coastal regions or chemically aggressive environments.

Typical applications include:

• Medium voltage overhead distribution networks
• Rural and remote area electrification
• Power supply for residential and commercial zones
• Industrial power distribution systems

The twisted configuration improves flexibility and reduces wind load, making it ideal for installation in areas exposed to strong winds or challenging terrain. It is also suitable for upgrading existing overhead lines to improve safety and reduce maintenance requirements.
