Commonly Used Cable Types and Their Applications in Distribution Network Engineering:
Aerial Bundled Cable (ABC):
Application: Widely used in low-voltage distribution lines, urban and rural grid renovation projects. It has excellent lightning protection, short-circuit prevention, and anti-theft performance, making it ideal for densely populated and complex environments.
Features: The wire is typically wrapped in insulating materials to effectively prevent short circuits caused by contact with branches, buildings, etc.
Bare Conductor:
Application: Mainly used in overhead high-voltage transmission lines and low-voltage distribution lines, suitable for areas that are far apart and have better conditions.
Features: The wire is not insulated, making it suitable for open environments with minimal interference and risk, offering good electrical conductivity.
Steel Core Aluminum Reinforced Cable (ACSR):
Application: Widely used in high-voltage and medium-voltage transmission lines, especially for long-distance, high-capacity power transmission.
Features: Composed of a steel core and aluminum wire, the steel core provides mechanical strength, while the aluminum wire ensures good conductivity. It can withstand large loads and resist harsh weather conditions like wind and snow.
Aluminum Alloy Conductor (AAC):
Application: Suitable for medium and low-voltage power systems, commonly found in urban power distribution networks and light transmission systems.
Features: Compared to regular aluminum conductors, aluminum alloy conductors offer higher strength, lighter weight, and better corrosion resistance, making them ideal for use in complex environments.
Polyethylene Insulated Cable (PE Insulated Cable):
Application: Commonly used in indoor or underground low-voltage distribution systems, particularly in urban distribution networks and residential areas.
Features: Provides strong insulation performance, is suitable for low-voltage environments, and can remain stable even under harsh weather conditions.
Cross-Linked Polyethylene Insulated Cable (XLPE Insulated Cable):
Application: Widely used in low-voltage and medium-voltage cable lines within distribution networks, especially in industrial and commercial areas with dense power consumption.
Features: Cross-linked polyethylene offers excellent heat resistance, voltage endurance, and corrosion resistance, making it a common choice for high-voltage and medium-voltage distribution systems.
Rubber Insulated Cable:
Application: Primarily used for low-voltage equipment distribution lines, especially suitable for mobile devices or environments with complex conditions, such as electric tools or welding machines.
Features: Offers high abrasion resistance, flexibility, and low-temperature endurance, but is mainly limited to low-voltage environments.
