Aerial Bunched Cables, Thcikness : 1.5-2mm, 2.5-3mm

In Aerial Bunched Cables, there are three insulated cores and one insulated neutral core (optional) present around a bare or covered messenger wire, carrying the load of the cable. There can be one additional power core for street lighting.
Power And Neutral Cores : Here, the conductor is composed of h2 or h4 grade aluminum of class 2 grade to is: 8130/84. Popular sizes are 16mm² to 95mm². Again, insulation can be either cross linked polyethylene or polyethylene.
Messenger Conductor : These are made of either galvanized steel or aluminum alloys.
Core identification : Either by number printing or by ridges on insulated cores; in comparison to bare overhead lines, Aerial Bunched Cable has very high degree of safety and reliability due to the conductors being insulated with the best dielectric medium. This, resultantly, ensures good protection against ground and line faults leading to considerable increase in system efficiency as against bare overhead lines. The problem of free-clearance is also minimized. Aerial Bunched Cable system is specially suited in limited space conditions such as densely populated areas where installing underground cables is impossible or extremely expensive.
Benefits :

• High degree of safety and reliability
• Tampering with power-line like hooking also gets eliminated resulting in much more efficient utilization of power
