What is the formula for calculating cable size?
Let’s select 3.5 core 70 Sq.mm cable for single run.
- Current capacity of 70 Sq.mm cable is: 170 Amp, Resistance = 0.57 Ω/Km and.
- Total derating current of 70 Sq.mm cable = 170 · 0.93 = 159 Amp.
- Voltage Drop of Cable = (1.732 · Current · (RcosǾ + jsinǾ) · Cable length · 100) / (Line voltage · No of run · 1000) =
What factors affect cable tension?
Factors affecting the sag
- Conductor weight – Sag of the conductor is directly proportional to its weight.
- Span – Sag is directly proportional to the square of the span length.
- Tension -The sag is inversely proportional to the tension in the conductor.
- Wind – It increases sag in the inclined direction.
Does cable length affect tension?
The lengths of the strings do not affect the tension. Question about tension in strings with different lengths and angles.
Are cables always in tension?
RE: Is cable always tension only object? Nope, not like a derailleur; no springs. Fat cable, push and pull.
Can cables be under compression?
Errors in cables can occur from the most innocent actions, even binding a group of wires too tightly. This type of error is called a compression failure and is caused when insulation narrows from its normal thickness.
Are cables in tension or compression?
Our arms are in tension, since they are being stretched from the weight of each other. This relates to question 6 because the cables are also in tension, like our hands and arms.

What is it called when a string is pulled tight?
In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements.
