Overhead insulated Cable /MV covered Aerial Cable(Space cable Or Tree Wire) 15kV /25kv/35kv Tree Wire
(Alternative and Robust Design to Bare ACSR Conductors to Harden the Electrical Grids)
- Used for primary and secondary overhead distribution where limited space is available or desired for rights-of-way.
- • Tree Wire – Used for spans where trees crowd the right-of-way, such as in wooded residential areas.
- • Covered Aerial MV Cable – Installed with other Covered Aerial MV cables and a supporting messenger through a series of space- maintaining devices (spacers).
- • Covering Rated 90°C Normal and 130°C Emergency Operation
