1. Good electrical conductivity: Because there is no insulating layer, the current transmission efficiency is high, the resistance is small, and the power loss can be effectively reduced.
2. The cost is relatively low: compared with insulated wires, the cost of insulating materials is saved, and the price is more economical.
3. Good heat dissipation performance: When the current passes through, the heat can be quickly dispersed to the surrounding environment, which helps to improve the current carrying capacity of the wire.
4. High mechanical strength: can withstand large tension and tension, suitable for long-distance overhead transmission lines.
