ABC cable (Aerial Bundle Cable) is a power cable used in overhead transmission and distribution systems. It consists of wires, insulation and outer sheathing and is typically used in outdoor environments. ABC cables usually consist of the following parts:
1. **Conductor**: The conductor of ABC cable is usually composed of aluminum alloy or copper conductor, which has good electrical conductivity. Aluminum alloy conductors are commonly used in medium and low voltage transmission lines, while copper conductors are used in high voltage transmission lines.
2. **Insulation layer**: The outside of the wire is covered with an insulation layer, usually made of materials such as polyethylene (PE) or cross-linked polyethylene (XLPE). The purpose of the insulation layer is to prevent current leakage and protect the wires from the external environment.
3. **Outer Sheath**: The insulation layer is covered with an outer sheath, usually made of a material with good weather resistance, such as polyvinyl chloride (PVC). The outer sheath protects the cable from UV rays, rain and other external factors, extending the cable's service life.
The advantages of ABC cable include easy installation, low maintenance cost, strong ability to withstand harsh weather conditions such as wind and rain, and is suitable for various environments. It is widely used in power systems in cities, rural areas, industrial and mining enterprises, buildings and other places to provide reliable power transmission solutions for power supply, transmission and distribution.
Overall, ABC cable is a high-performance power cable that plays an important role in overhead power transmission and distribution systems.
