Send An EmailTree Wire is overhead insulated cable, used for primary and secondary overhead distribution with limited space or rights-of-way, such as alleyways or tight-corridors. It can be installed the same as bare overhead conductors. It’s effective in avoiding direct shorts and instantaneous flash overs with other objects.
Tree Wire
when used in a tree wire power system, it is installed in a flat configuration, in a similar manner and spacing on insulators as with bare or covered overhead conductors. Self-supporting conductors, such as ACSR, are typical in this type of installation.
Spacer Cable
when used in a spacer cable power system, it is installed with a uniform spacing in a diamond configuration maintained by spacer hardware. The spacer and cable assembly are supported by a bare messenger, such as bare aluminum clad steel, ACSR, OPGW, or galvanized steel wire. Spacer cable assemblies occupy minimal space, requiring the narrowest of right of way or corridor.
