Covered Aerial MV Cable – Installed with other Covered Aerial MV cables and a supporting messenger through a series of space-maintaining devices (spacers). The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation, which is particularly useful in congested areas.
Tree Wire – Used for spans where trees crowd the right-of-way, such as in wooded residential areas, when a minimum of interference with the environment is desired. Covering minimizes power outages due to conductor contact with tree limbs, reducing the need for frequent or severe trimming.
Spacer Cable – Installed with other spacer cables and a supporting messenger through a series of space-maintaining devices (spacers). The resulting close proximity configuration minimizes the amount of space and hardware required for line installation; particularly useful in congested areas.

- Rural Electrification: In rural areas with relatively scattered loads, it can transmit power over long distances with less loss and supply electricity to rural households and small industrial and commercial users.
- Overhead Distribution Lines: It is often used in overhead power distribution systems in cities and suburbs to distribute power from substations to various load points.
- Areas Prone to Tree Contact: As its name implies, it is suitable for areas where there are many trees. It can reduce the occurrence of faults caused by tree branches contacting the lines and improve the reliability of the power supply.
- Conductor: Usually made of high-conductivity copper or aluminum, available in stranded or compacted forms like AAAC.
- Insulation: Commonly uses materials like cross-linked polyethylene (XLPE), low-density polyethylene (LDPE), or high-density polyethylene (HDPE).
- Optional Layers: May include a conductor shield.
