Construction
The tree wire is designed with concentrically stranded conductors - AAC (1350-H19) which are either compressed or compact depending on conductor size, available with AAAC or ACSR. The conductors can be covered with high-density track-resistant Polyethylene (HDTRPE) or track-resistant crosslinked Polyethylene (XLPE) insulation to meet different applications.

Application
The tree wire is used for primary and secondary overhead distribution where limited space is available or desired for rights-of-way. Installed the same as bare conductors, however, covering is effective in preventing direct shorts and instantaneous flashovers with other objects.
The close-proximity configuration minimizes the amount of space and hardware required for line installation, making it particularly useful in congested areas such as alleyways or tight corridors.

Specifications
35kV covered multi-layer tree wire meets or exceeds all applicable ICEA specifications and the following ASTM specifications:

  • ASTM B230
  • ASTM B231
  • ASTM B232
  • ASTM B398
