　　Advantages of overhead insulated conductors;

　　Overhead insulated wire

　　Chinese name: Overhead Insulated Line

　　English name: Aerial insulation line

　　Definition: A wire with a single or multiple layers of aluminum stranded wire and extruded insulation layer on top

　　The so-called overhead line is relative to the cable, which refers to the transmission of electrical energy through the installation of wires at a certain height by towers. For high-voltage transmission and distribution network overhead lines, ground insulation is generally achieved through air. Previous distribution lines (except for 380V below 10kV) also used bare wires. However, due to the complex distribution environment in urban areas, short-circuit grounding and lightning strikes often occur on the lines, resulting in reduced power supply reliability. Therefore, currently, insulated wires (i.e. insulation layer wrapped around the outer layer of the wire) are generally used for overhead lines below 10kV, which is called insulated overhead lines

　　There are two types of overhead lines: low voltage and high voltage. Generally, there are many types of overhead lines, such as streetlight overhead lines, JKLYJ*10KVA*50*100， This explains the voltage, model, material, core cross-sectional area, and length of the overhead line.

　　Overhead insulated lines are mainly used in salt spray areas. Salt spray causes severe corrosion to bare wires, greatly reducing their tensile strength. When exposed to wind and rain, it can lead to wire breakage, which can easily cause short-circuit grounding accidents. The use of overhead insulated wires can effectively prevent salt spray corrosion. Delay the aging of the line and extend its service life.

　　Areas with frequent lightning strikes. Due to the insulation protection layer, overhead insulated wires can reduce lightning strikes and minimize power outages caused by grounding faults.

　　Renovation of old urban areas. Due to the fact that overhead insulated conductors can withstand a voltage of 15kV, the small vertical distance between insulated conductors and buildings is 1m, and the horizontal distance is 0.75m. Therefore, replacing low-voltage main lines with 10kV overhead insulated conductors and directly sending them to the load center can reduce the occupied space of distribution lines.

　　Typhoon areas. Due to the poor typhoon resistance of overhead bare wire lines, the line trips one after another when a typhoon arrives. After using overhead insulated wires, the instantaneous collision of wires will not cause short circuits, reducing faults and greatly improving the typhoon resistance of the line. Salt spray areas. Salt spray causes severe corrosion to bare wires, greatly reducing their tensile strength. When exposed to wind and rain, it can lead to wire breakage, which can easily cause short-circuit grounding accidents. The use of overhead insulated wires can effectively prevent salt spray corrosion. Delay the aging of the line and extend its service life.

　　Areas with frequent lightning strikes. Due to the insulation protection layer, overhead insulated wires can reduce lightning strikes and minimize power outages caused by grounding faults.
