What else can I help you with?
What might happen if the electrical cables were installed tightly with no slack?
If you don't allow the conductors to sag then, when they contract in cooler weather, they could (a) snap, (b) break their insulators, (c) pull poles over, or (d) pull intermediate poles out of the ground.
What is a Continuity test on Electrical Cables?
Continuity of electrical cables must, because it is the process of inspection to found any discontinuity in the cable
What is meant by pull back effect when pulling in electrical cables in conduit?
what is meant by pull back effect when pulling in electric cables in conduit
What system of high tension cables by which electrical power is distributed throughout region?
Power lines
Electrical equipment PAT?
Portable appliance testing (PAT) is basically a method of testing (using a device and by sight) that any electrical equipment, cables, devices, machinery is safe to use.
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 cables sag?
Cables are made out of metals which has the property of expanding on heat and contracting on cold due to elasticity hence they sag during summer
How do you remove electrical cables without damaging existing cables?
How do you remove electrical cables without damaging existing 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.
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.
What form of energy does electrical cables?
Electric cables carry electrical energy in the form of electricity.
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. Are metals used for making electrical cables?
aluminium is used for making electrical cables as the metal do not melt easily
What is the purpose of a conductor shield in electrical cables?
The purpose of a conductor shield in electrical cables is to protect the conductor from electromagnetic interference and to prevent leakage of electrical signals.
What might happen if the electrical cables were installed tightly with no slack?
If you don't allow the conductors to sag then, when they contract in cooler weather, they could (a) snap, (b) break their insulators, (c) pull poles over, or (d) pull intermediate poles out of the ground.
Why not touch overhead cables with branches?
Touching overhead cables with branches can be extremely dangerous because these cables often carry high voltage electricity. If a branch comes into contact with the wires, it can create a path for electrical current to travel, potentially causing electrocution or fires. Additionally, the added weight of branches can cause the cables to sag, increasing the risk of accidents. It's important to maintain a safe distance from overhead power lines to prevent these hazards.
What is a Continuity test on Electrical Cables?
Continuity of electrical cables must, because it is the process of inspection to found any discontinuity in the cable
