Enter the conductor span (mm) and sag (mm) into the Calculator. The calculator will evaluate the Conductor Length.

## Conductor Length Formula

CL = Sp + ((8*Sa^2)/(3*Sp))

Variables:

- CL is the Conductor Length (mm)
- Sp is the conductor span (mm)
- Sa is the conductor sag (mm)

## How to Calculate Conductor Length?

The following steps outline how to calculate the Conductor Length.

- First, determine the conductor span (mm).
- Next, determine the conductor sag (mm).
- Next, gather the formula from above = CL = Sp + ((8*Sa^2)/(3*Sp)).
- Finally, calculate the Conductor Length.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

conductor span (mm) = 30

conductor sag (mm) = 4.5
