What is a characteristic of tree wire?

Tree wire is specifically designed to provide protection from branch-related faults, which is its defining characteristic. This type of wire typically features a coating that helps resist damage caused by contact with tree branches and other vegetation, minimizing the risk of outages and enhancing safety. The protective coating is crucial for outdoor overhead applications where such contacts are more likely to occur.

The other choices reflect common misunderstandings about tree wire. While the option mentioning insulation implies careful handling, tree wire is often bare and does not require special handling in the same way that insulated wire does. The statement about exclusive underground use is inaccurate since tree wire is primarily used in overhead applications. Lastly, while conductivity is important in electrical wiring, tree wire does not necessarily have a higher conductivity than regular wire types; conductivity would depend more on the material and gauge of the wire rather than its classification as tree wire.
