Question 1

When line distribution line mans are planning for the job. There are several factors involved to be considered to prevent accidents. name all of them.

Answer 1

1. what area in the job needs to be protected with cone and sign.
2. can the equipment and the line be deenergized?
3. who is responsible for switching?
4. are there any grounding that needs to be applied?
5. what kinds of rubber gears are needed?

Question 2

Name the 3 common types of secondary wire.

Answer 2

1. Open Wire secondary
2. Parallel aerial cable
3. Triplex or quadruplex

Question 3

Explain open wire secondary.

Answer 3

Open wire secondary has two or more single conductors were the wires are distanced from each other.

Question 4

Explain Parallel arial cable or pre-assembled secondary.

Answer 4

This type of cable are ran parallel close to each other as shown In the photo.

Question 5

What does ACSR Mean?

Answer 5

Aluminum conductor still reinforced

Question 6

Explain Triplex or Quadruplex secondary cable.

Answer 6

Triplex is consist of two or more conductors and neutral messenger.

Question 7

What does paralleling service conductors mean?

Answer 7

It means that the new wire is connected to service while the other one is still connected and energized.

Question 8

When installing a parallel service what is the correct order of installing cables?

Answer 8

The correct order is to install the neutral wire first.

Question 9

When paralleling the secondary line how do you make sure that the two conductors that are going to be bound together are from the same leg feed of the transformer?

Answer 9

We will use the volt meter, if the voltage is zero between two legs of conductors it means that they are in the same leg and if the result was 240 it means that they are not.

Question 10

What is the insulated platform ?

Answer 10

The insulated platform is a device that attaches to the pole and allows the line man to step on it and work on it while its providing the insulation from energized line.

Question 11

Name all the reasons to use the Dead-End insulator.

Answer 11

1. To make an open loop
2. To redistribute a load
3. to separate circuits
4. Isolate sections

Question 12
