Conducting The Energy - Xinfeng Cable

25kV Spacer Cable Tree Wire

15-35kV Medium voltage Spacer Cable Tree Wire

Applications

This cable can be used for primary or secondary overhead transmission lines and is commonly used in wooded areas. 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.
