The voltage of overhead insulated cable is 0.6/1KV. It is an insulated overhead wire. The conductor is generally AAC, AAAC stranded wire, and the insulation material is 90℃ cross-linked polyethylene. Rated voltage: 600/1000V，Insulation material: Cross-linked polyethylene
1.Power transmission： The power generated by the power plant is transmitted to the substations in various cities and regions through overhead insulated wires
2.Power distribution： The high-voltage power from the substation is converted into low-voltage power and transmitted to homes, commercial buildings, industrial facilities and other places for human use.
3.Power supply for electrified railways： Overhead insulated wires are often used to supply power to electrified railways such as trams and subways.
1.Conductor： The wire core has a circular cross-section. Bundled conductors with or without supporting cores, auxiliary cores or grounding cores or a combination of the above cores. The outermost stranding direction of the conductor is left. In ABC cables, steel-cored aluminum stranded wires or Aluminum alloy stranded wires make conductors.
2.Insulation： The insulation layer of ABC cables is usually made of cross-linked polyethylene material, which has excellent pressure resistance and insulation properties. The thickness of the insulating layer can be designed and adjusted according to the use environment and electrical requirements
3.Cabling： Multi-core cables (multiple-conductors) should be cabled, the cabled direction is right, and the cabled pitch ratio is 60 times.
1. Low operating cost： The construction cost, operating cost and maintenance cost of overhead insulated cables are lower than those of underground cables because they do not need to be laid, excavated, backfilled, etc. underground, and are easier to repair and replace.
2. Troubleshooting： Convenient Overhead insulated cables are easy to find and locate when they fail, and can be repaired at a relatively fast speed to ensure the reliability of power supply. Once an underground cable fails, it may be more troublesome to find and the repair time will be relatively long.
3. Wide scope of application： Overhead insulated cables are suitable for various harsh environments, such as strong winds, lightning strikes, etc., while underground cables are greatly affected by geological conditions and the environment, and may not be suitable for all regions and application scenarios.
4. Fast construction speed Overhead insulated cables can be directly erected in the sky, without being restricted by terrain and buildings, so the construction speed is faster.
