IS 14255 India Standard Aerial Bundled Cable with AAAC Neutral and Street Light
APPLICATION
The Areial Bundled Cable are designed for overhead distribution lines have an insulated neutral messenger made of AAAC, which the insulated aluminum phase conductors are helically wound over it. Street light wire are available according to requirement.
The main advantage of aerial bundled cables included
1.Easy of erection and stringing.
2.Practically no tree-trimming required
3.Less maintenance.
