Why are electrical cables set to sag?
because of heat cables expand
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
Why are the main support cables of the suspension cables designed to sag?
They can't be designed not to. Large cables and ropes are extremely different to stretch straight, because of their high weight-to-length ratio.
Why overhead electric cables sag on hot sunny days?
There's little choice. Conductors (not 'cables') sag, because of their weight. However, there's also a practical reason for deliberately allowing conductors to sag; if they were too 'tight', then they would not be able to contract during cold weather without pulling the poles over.
Why does over heated electricity cables sag in during day time?
Electricity cables sag in during the day because they expand and elongate as they heat up. The increased temperature weakens the cable's structural integrity, causing it to sag under its own weight. This is a natural response to thermal changes and is managed by engineers to ensure safety and reliability.
What is the definition for suspension?
Suspension structures are those with horizontal planes (road decks, roofs, and even floors) supported by cables (hangers) hung from the parabolic sag of large, high-strength steel cables.

Why do they hang hydro cables a little instead of being stretched?
Hydro cables are hung with a slight sag instead of being tightly stretched to accommodate thermal expansion and contraction due to temperature changes. This sag helps prevent excessive tension that could lead to cable breakage or damage due to wind, ice, or other environmental factors. Additionally, the slack allows for movement and flexibility, reducing stress on the support structures. Proper sag also helps maintain the cable's electrical properties and safety standards.
What is to hang or sink downward?
sag
What is sag in eee?
Sag in electrical engineering, particularly in the context of overhead transmission lines, refers to the vertical displacement of the line due to its own weight and the tension in the cables. It is influenced by factors such as the span length between supports, the weight of the conductor, and the tension applied. Proper sag management is essential for ensuring safety, maintaining electrical clearances, and optimizing the performance of the transmission system. Engineers calculate sag to prevent excessive drooping that could lead to contact with vegetation, structures, or other hazards.
What is a three letter word which means to hang or sink downward?
