Application

Aerial Cable (tree wire and spacer cable) is intended for use in overhead primary and secondary distribution systems rated 25 kV (nominal) typically to prevent faults due to contact or where space is limited.
The track resistant 3-layer system prevents short-circuits and flashovers in the case of contact with trees or wildlife. When installed correctly, this system is effective at preventing system outages, damage, or fires as a result of falling trees or branches.

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.

Construction

Conductors are concentrically stranded, AAC (1350-H19), either compressed or full compact depending on conductor size, AAAC or ACSR. Available with high-density track-resistant polyethylene (HDTRPE) or Track-Resistant Crosslinked Polyethylene (XLPE) covering. Strand shield option available as shown in illustration.
