　　Characteristics of overhead insulated conductors;

　　The application area of overhead insulated conductors is suitable for areas with multiple trees. The installation and maintenance of bare wire lines in areas with many trees often have a significant impact on greening and forestry. The use of overhead insulated wires can reduce tree felling (during the initial installation and operation maintenance stages), solve many problems, reduce conflicts with departments such as greening and forestry, protect the ecological environment, beautify the city, and reduce line grounding faults.

　　Used in areas with frequent flying metal dust and pollution. In the old industrial area, due to inadequate environmental protection standards, metal processing enterprises often have flying metal dust in the wind. Causing short circuits and grounding faults in overhead distribution lines in polluted areas of thermal power plants and chemical plants. The use of overhead insulated conductors is a better way to prevent short-circuit grounding of 10 kV distribution lines.

　　Suitable for 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, causing short-circuit grounding accidents and shortening the service life of the line. The use of overhead insulated wires can effectively prevent salt spray corrosion. Because of the insulation layer protection, it can reduce the corrosion of conductors by salt spray, delay the aging of the circuit, and extend the service life of the circuit.

　　Suitable for areas with frequent lightning strikes. Due to a layer of insulation protection, overhead insulated conductors can reduce lightning strikes on the line, and even if there is lightning, the impact will be much smaller. In the minefield, the insulation of the lines erected with bare wires generally decreases rapidly, and there are often ground burst accidents. After replacing with overhead insulated wires, the power outage time for grounding faults can be reduced.

　　Suitable for the renovation of old urban areas. Due to the fact that overhead insulated wires can withstand a voltage of 15kV, the small vertical distance between insulated wires and buildings is 1m, and the horizontal distance is 0.75m. Therefore, replacing the low-voltage main line with 10kV overhead insulated wires and directly sending them to the load center to shorten the radius of the low-voltage power grid is an effective distribution method for urban renewal.

　　Beneficial for preventing typhoons. 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.

　　Transportation precautions;

　　It is strictly prohibited to throw cables or cable reels containing cables from a height during transportation, especially at lower temperatures (usually around 5 ℃ or below). Throwing or dropping cables may cause insulation and sheath cracking. Try to avoid storing cables in an exposed manner outdoors as much as possible, and cable reels are not allowed to be laid flat. When lifting the packaging of the JKLYJ overhead line model, it is strictly prohibited to lift several reels at the same time. On vehicles, ships, and other transportation vehicles, cable reels should be secured using appropriate methods to prevent collisions or tipping over, in order to prevent mechanical damage to the cables. Cables must not come into contact with acids, alkalis, and mineral oils, and must be stored separately from these corrosive substances There shall be no harmful gases that damage insulation or corrode metals in the warehouse where cables are stored. During the storage period, the cable should be rolled regularly (once every 3 months in summer, and may be extended at discretion in other seasons). When rolling, roll the storage tray upside down to prevent the bottom from getting damp and rotting. When storing, it is important to regularly pay attention to whether the cable head is intact and undamaged.
