0.6/1KV overhead insulated cable is an overhead conductor with an insulating layer. The conductor is generally AAC, AAAC, ACSR stranded wire, and the insulation material is 90℃ cross-linked polyethylene. This Peruvian technical standard specifies the requirements that copper or aluminum conductors insulated with cross-linked polyethylene (XLPE) wound on supporting cables must meet.
Overhead insulated cables are often used in urban and rural power grid transformation, road lighting and other lines.
1.Power transmission:Overhead insulated wires can transmit electricity from power plants to substations in various cities and regions
2.Power distribution:Overhead insulated cables convert high-voltage electricity from substations into low-voltage electricity and transmit it to homes, commercial buildings, industrial facilities and other places for people to use.
3.Electrified railway power supply:Overhead insulated wires can provide power for electrified railways such as trams and subways..
1.Conductor:The core of the conductor is a circular cross-section, the outermost layer of the conductor is stranded on the left, and the conductor material used is steel-cored aluminum stranded wire or aluminum alloy stranded wire
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:Compared to underground cables, overhead insulated cables have lower construction and operation and maintenance costs because they are easier to repair and replace, and do not require underground laying, excavation, backfilling, etc.
2.Troubleshooting:Convenient The fault location of underground cables is more troublesome and the repair time will be longer, while the fault of overhead insulated cables is easy to find and locate, and can be repaired faster to ensure the reliability of power supply.
3.Scope of application:Wide Overhead insulated cables have stronger environmental adaptability and can be used in 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.Construction speed:Fast The construction speed of overhead insulated cables is faster because they are not restricted by terrain and buildings, and the construction speed is faster, and they can be directly erected in the air.
