Foundations are the main cause of any building sinking. As the house moves its structure is under differing stresses and this causes the fabric of the housee o eventually break in areas such was walls, floor/ceilings and door ways and windows start becoming twisted.

Sag produced in the conductor of a transmission line depends on?

-The tension of the cable (the tighter, the less sag, but this can cause other problems if too tight) -The temperature outside (the higher the temperature, the more it will sag) -The amount of current flowing through the cable (the more current, the hotter the conductor will get = more sag) -The type of cable (aluminimum will sag more than copper; ACSR will sag less than straight aluminimum).


When Ontario Hydro workers set up electrical cables during the summer they allow the cables to sag. Suggest a reason for this. In your answer refer to the particle theory?

i know someones going to be on this sooooooooo....... they sag because the hydro workers know, from the heat the cbles will sag during the summer, so they start the sag so they cant sag anymore


How do sag's in power transmission formed?

The plural of sag is sags, not sag's! Sag is caused by the weight of the conductor between its supports, and is (a) unavoidable and (b) necessary to allow for the conductor's expansion and contraction during variations in temperature. When surveyors design a power line, the amount of necessary sag is calculated and built into the design, while ensuring that the clearance between the conductor and the ground remains within safe limits.


What causes gurgling in house pipes?

Probably an air-lock somewhere !


What is Sag Compensating Springs for Pantograph Isolator?

i think sag compensation springs are used in dead end termination of quadra conductor bus where jack bus is passing below bus & required clearence if we are not getting betn two buses their these sag compensation springs are used to bring conductor under tension .
