understanding of the basic concepts

1. Dead-end pole: Dead end pole is a pole, which itself supports 8 aerial cable or a steel cable stretched displays and ends in a dead-end device

.
2. Wingspan Messenger: Messenger span refers forward to the length of continuous steel cable between two poles impasse

.
3. Between poles: poles are all the intermediate steps between two poles dead end poles

.
Planning

1. Careful planning and preparation are required prior to installation of overhead lines. During the cable route survey, representatives of the parties concerned, including utilities, etc. have to pay road be present. Before the planning even begins, the consent of all parties are caught up in detail. Ample space will be confirmed for the cable along the new right of way must be covered during the survey period range.

2. Existing poles should be used when possible to save costs.

3. When moving on a pole, the antenna fiber cable? Fiber optic cables weigh less than comparable copper cable, and even less of an arrow, fiber optic cable to the highest space communications to occupy on a pole.

4. Adequate working space must be between the fiber optic cables and electrical cables are kept on poles for sharing. You need to consult the National Electrical Safety Code for the appropriate permissions.

5. can evaluate existing pole dead end if they can withstand the stresses during the installation of overhead lines. They must assess whether temporary guying is needed to temporarily relieve the stress during the installation of the cables are unbalanced.

6. Splice sites. Splice sites are generally selected on cable route survey. You have chosen to allow as long continuous cable spans and a minimum number of connections. They shall be easily accessible to a vehicle splicing.

7. Aviation system must not be carried out in wet conditions. And make sure all employees properly trained for the work of the fishing lines.

8. be fiber optic cables (including all dielectric cable) must be properly grounded when installed near high voltage electric cable.

: Installation
Installation of aerial fiber optic cable can happen in two ways

1. By securing a fiber optic cable to a steel rope />
A messenger steel is first installed between the poles. Then a cable reel trailer and truck used to pull the cable along the mail. A guide wire, and ligature wires are wrapped both the messenger and the fiber cable to fiber optic cables attach to the messenger. After ligation, a bucket truck aerial cable is carrying out the necessary adjustments.

At each pole of the fiber optic cable, a loop expansion for the development allow for the messenger. The loop size expansion in length and depth, its length must be greater than twice its depth. The fiber optic cable that is their minimum bend radius at all times.

2. The direct integration of figure 8 self-support fiber optic antenna

Self-supporting cable (Figure-8) fiber simplifies the task by fiber optics on a floor plant. The figure-8 self-support cable includes both a messenger of steel and glass in an envelope of figure-8 section.

The combination of beach and fiber-optic cable allows a single installation in one quick step and results in a more sustainable aviation plant.
