Five advantages of safety performance of aluminum wire used for power lines
1. Good electrical conductivity.
The conductivity of the new alloy cable treated by a special process is 62% of copper. After a special process, the cross-section of the alloy conductor is increased by 1.28-1.5 times, so that the current-carrying capacity and voltage drop of the cable are equivalent to that of the copper cable, and the purpose of "substituting new alloy materials for copper" is achieved.
2. Excellent anti-corrosion performance.
When aluminum wire used for power lines is in contact with air, a dense oxide layer is formed immediately. This oxide layer is particularly resistant to various forms of corrosion, so it has the characteristics of withstanding harsher environments; in addition, the optimization of the internal material structure of the alloy conductor and silane The application of cross-linked polyethylene insulation material makes the service life of alloy cables longer than copper cables by more than 10 years.
3. Superior mechanical properties.
The rebound performance of aluminum wire used for power lines is 40% lower than that of copper cables, and its flexibility is 25% higher; it has good bending performance, and the laying radius is much smaller than copper cable requirements, making it easier to lay and connect terminals; special formula and heat treatment The process greatly reduces the creep of the conductor under heat and pressure, and makes the electrical connection of the alloy cable as stable as the copper cable.
4. Saving economic performance.
Under the premise of achieving the same electrical performance, the direct purchase cost of aluminum wire used for power lines is 20%-30% lower than that of copper cables; because the weight of alloy cables is only half that of copper cables, and they have good mechanical properties, they are used Alloy cables can reduce transportation and installation costs. General buildings can save installation and construction costs by more than 20%, and large-span buildings can save more than 40%.
