L.T. AERIAL BUNCHED CABLE

Application:

Aerial Bundled cable are suitable for the following functions:

In power theft prone areas.
As replacement of bare lines in rural areas, in woods, other localities & narrow street where space is limited.
As replacement of bare lines where reliability of supply is of prime importance and where high degree of stability of supply voltage is of importance.
In hilly terrains where cost of erection of overhead lines of under ground cable becomes very high.
In hilly terrains where cost of erection of overhead lines of under ground cable becomes very high.
As reinforcement of existing system without increasing voltage.
For temporary supplies.

Quality:

Production accroding to NFC-33 209

Construction:

Conductor	The phase conductor and neutral/street lighting conductors is of H2 or H4 grade aluminium complying with the requirements of IS 8130:1984 and conforms to flexibility class 2 of IS 8130:1984. The size of the street lighting conductor is16 mm2.
Messenger (Neutral Conductor or Otherwise)	The conductor is heat treated aluminium- magnesium-silicon alloy wire conforming to IS 398 (Part 4):1979.It is either stranded circular or compacted circular type and has minimum 7 strands with smooth surface.
Insulation	The conductor is insulated with crosslinked polyethylene applied by extrusion. The insulation so applied fits closely on the conductor and it is possible to remove without damaging the conductor. The color of insulation is black, offering UV protection
