1. Good insulation performance: can effectively prevent leakage and short circuit, improve the safety and reliability of power supply.
2. Resistance to external environmental interference: It has good weather resistance and corrosion resistance, and can operate stably in outdoor harsh environment for a long time to reduce maintenance costs.
3. Increase transmission capacity: Compared with traditional bare overhead wires, its insulation performance allows for a more compact line arrangement, thereby improving the transmission capacity of the line.
4. Reduce line loss: Due to the existence of the insulation layer, it reduces the reactance and reduces the loss of electrical energy on the line.
5. Easy to lay and install: relatively light weight, construction is more convenient.
