PVC Cables (Aerial Bunched Cables):
Superlink Polyfeb Ltd., which has been manufacturing ACSR Conductors
since 2003, can now suppy the full range of Low Voltage Aerial Bunched Cables.-
Aerial bunched cables are a better alternative to bare overhead wires
in distribution networks, particularly in rural and suburban areas.
Since, the cores are insulated, they are intrinsically safe and reliable,
-
Experience has shown that, even though the initial cost of an aerial
bunched cable line is slightly higher than that of a bare overhead wire
line, the ultimate cost of this type of cables systems is less, if the
following points are taken into consideration.
-
The inductance in aerial cables is much less than the wire systems, because
of the proximity of the phase conductors, making the voltage drop lower
per unit of length
-
Trees require less trimming where lines run through wooded areas. Costs
for repair and maintenance are less since, there is no risk of damage
due to fallen trees or accidental contact between conductors in high
winds
-
The poles can be used for additional power or telephone lines. Several feeders can be installed on the same pole. Aerial cables can be attached to any kind of pole or wall and can safely be installed in narrow streets.
-
Aerial cables are very versatile as they can be re-used in conjunction with temporary services, camps, construction sites, etc.
-
Additional branch connections can be easily and safely made by linesmen
using insulation piercing connectors and insulated tools.
