Question

Which of the following is NOT necessary to be checked while maintaining stay wire?
1. Creeper on the stay wire
2. Guy wire tightness
3. Inclined length of stay wire
4. Corrosion of guy rod and stay wire

Answer 1

Correct Answer - Option 3 : Inclined length of stay wire

Stay Wire:

• Stay wire is used in the electrical distribution pole for balancing the mechanical load on the electric pole.
• When the electrical line is straight, the load on the pole is vertically downward.
• However, at the junction point, or if there is a turn in the electric line, there is also a horizontal component of load on the pole.
• In the long run, due to this continuous load, a pole may bend or the line may bend.
• Stay is provided to balance the horizontal component of the load on the pole mainly.
   

Necessary condition while maintaining Stay Wire:

• It should be tight to balance the mechanical load.
• Any biological species contains water, the same is the thing for creepers and weeds at the end base of the pole.
• Should be free from corrosion.
• The strain insulator is inserted between stay wire to isolate the lower portion from electricity. It may also be used where a wire attaches to a pole or tower, to transmit the pull of the wire to the support while insulating it electrically
