80% of the South American market uses aluminum cables. In other countries, large operators such as Telefonica, T-Mobile, Malaysia Telecom, O2, BT, etc. have applications and accumulated a large number of application cases.
The aluminum alloy cable with high cost performance and excellent mechanical performance has been used in Europe and the United States for nearly 50 years, and its utilization rate is particularly prominent in hospitals, churches and government agencies. In the cable market analysis center, although the sales volume of overhead cable is far from the power cable, small orders from government and rural infrastructure show a clear upward trend, which represents the most basic cable application of overhead lines.
