Product Overview
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 tree wire space and hardware required for line installation; particularly useful in congested areas such as alleyways or tight corridors.
