The LT Aerial Bunched Cables consist of insulated phase consuctors ( with additioanal street lighting conductor if provided ) are twisted around teh abre / insulated aluminium alloy messenger conductor, which atkes all the mechanical stress & also serve as the earth cum neutral conductor.

The phase conductor & street lighting conductor are insulated with Black weather resistant polyethylene or cross linked polyethylene.
