• Polycore uses only electrolytic grade conductor which is
99.9% pure, and hence resistance and heat generation
within the cable is minimum. |

Low grade wires and cables have lower cost but have
higher power losses and hence prove to be costlier in the
longer run. Made from poor impure grade of copper,
such cables have high resistance (ability to resist flow of
current) which increases power loss.
Electrical Power Loss is measured in units of KWH (kilo
watt hour)
Given by equation:
2 I RT
P = 1000
Here I = current ( in amperes) which is passed
through wire.
R = resistance(in ohms)
T = Time (in hours) for which current is passed
If resistance of cable is higher by just 1 ohm, then for a 5
amperes current, 18 units of more electricity will be
consumed. For an average cost of 4 Rs/ Unit, 18 units will
cost Rs. 72/ month.
This cost can be minimized by using cable with lower
resistance. Lower resistance not only saves power but also decreases voltage drop and ensure safety of your costly
equipments and gadgets. |
