2-Layer 15kV Tree Wire
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
15kV 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
- ASTM B399
- ASTM B400
ICEA S121-733
