Application
Used for primary and secondary overhead distribution where limited space is available or desirable for rights of way. Installed as an uninsulated conductor, however, covering is effective in preventing direct shorts and instantaneous flashovers should tree limbs or other objects contact conductors in such close proximity. The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation; particularly useful in congested areas such as alleyways or tight corridors.
Standard
Tree wire is manufactured to ICEA S-121-733 and should meet the following relevant standards:
ASTM B230
ASTM B231
ASTM B232
ASTM B398
ASTM B399
ASTM B400
Construction
Conductors are concentrically stranded, AAC (1350-H19), AAAC or ACSR. Available with high-density polyethylene (HDPE) or cross-linked polyethylene (XLPE) covering .
AAC- compressed stranding, 1350-H19 aluminum made to ASTM B231
AAAC- concentric stranding, 6201-T81 aluminum alloy made to ASTM B399
ACSR- concentric stranding, 1350-H19 aluminum with GA2 steel core made to ASTM B232
Coverings
High-density polyethylene (HDPE)
Cross-linked polyethylene (XLPE)
VOLTAGE
15kV, 25kV, 35kV, 46kV
