Calculating Tension in Overhead Conductor with added Wind pressure

AI Thread Summary
To calculate the tension in a 'Dog' overhead conductor over a 100m span with a wind pressure of 900Pa, one must consider the conductor's properties, including its diameter, weight, area, and breaking load (CBL). The initial tension is set at 10% of the CBL, and the calculation assumes no temperature changes. The term "Dog" refers to a specific type of conductor, while wind pressure in pascals can be converted from wind speed for accurate calculations. The modulus of elasticity is expressed in GPa, which is crucial for understanding material behavior under tension. Overall, the discussion emphasizes the need for basic catenary calculations when wind effects are considered.

Hi was wondering if anyone knows how to calculate the tension in a overhead conductor say 'Dog' conductor over a 100m Span with a wind of 900Pa given its properties are as below

'Dog' Conductor properties

Diameter = 14.15mm
Weight = 0.3965kg/m
Area = 118.8mm^2
CBL = 32.7kN
Expansion Co = 0.0000139
Mod of elasticity = 139

This is with an initial tension of 10% CBL.
And no change in temperature.

If we take away the wind, I would presume that this is a basic catenary calculation; do you agree? What does the term "Dog" denote? What does a wind load in Pa mean? We normally specify wind loading by giving wind speed, so what is this? What is CBL? What are the units on your modulus of elasticity?
 
Dog is the name of the type of conductor which is used. wind load is wind pressure which you can convert to from wind speed. CBL is calculated breaking load of the conductor and the units on the modulus of elasticity is GPa. Pa is pascals.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
