The advantage of the overhead line is that the simple structure, the convenient installation, the smaller investment, the large transmission capacity, the heat dissipation condition is good, and the maintenance is convenient. Good mechanical and electrical properties of overhead line cables. At present, overhead lines account for a large proportion of national infrastructure. Such as AAC, AAAC, ACSR, and aluminum abc cable.
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. In the field, it has been widely recognized, which means that the future of the overhead line is promising.
