How to install the ADSS fiber optic cable tension clamp? 5

1.Attach the U-shaped attachment ring to the extension rod.

2.Insert one end of the tensile pre-twisted wire into the U-shaped connecting ring.

3.Make the two ends of the tensile pre-twisted wire parallel to the optical cable, and mark the optical cable with tape according to the color code position on the tensile pre-twisted wire. The markings are used as a reference for the installation of the guard wire, the pre-twisted wire, and the pre-twisted wire.

4.Wrap the guard pre-twist pre-twist from the center of the sub-bundle, but leave the end of the guard pre-twist loose at the end.

5.Repeat the operation of the previous step to confirm that all the pre-twisted wires of the guard wire are installed smoothly and naturally without overlapping.

6.All guard pre-twisted wire installations (e.g. 5.)As described), wrap the ends around them with their bare hands. (Do not use any tools to avoid damaging or scratching the cable.) ）

7.Align the color scale of the tensile pre-twisted wire with the end color scale of the guard pre-twisted wire and the pre-twisted wire.

8.Starting with the identification of the color code, the other end of the tensile pre-twisted wire is also wound one or two times.

9.At the same time, the two ends of the tensile pre-twisted wire are wound until it is completed, and in this process, it is necessary to ensure that its end is bent outward along the radial direction of the optical cable, so as not to squeeze the pre-twisted wire of the guard wire. Be sure not to wrap one end in one go!

10.For ease of installation, it is also possible to divide the end of the tensile pre-twisted wire into several smaller sub-bundles. (Do not use any tools to avoid damaging or scratching the cable.) Make sure that all pre-twisted wires are wound smoothly and evenly and naturally.

11.Fix the U-ring on the corresponding tower fastening fixture. The tension clamp is installed.

Hello, ADSS tension clamp is a fixed fitting, a section fixed on the tower, or a rod, with a special link iron. The other end is the optical cable, which is generally operated by a special construction team to avoid subsequent troubles.

In the process of ADSS optical cable erection, attention must be paid to safety issues, in which the safety of personnel is the most important, and various safety rules and regulations must be complied with during construction.

About fittings. The fittings required for the installation of ADSS fiber optic cables include tensile fittings for tension towers, suspension fittings for suspension, anti-vibration whips, grounding wires and down-lead clamps. After the optical cable is connected, the whole process index test is carried out. The test instrument is generally OTDR, or the light source and optical power meter are used.

The test parameters are: Overall attenuation: should meet the design requirements, and should generally be less than for 1310 nm fibers. Contact attenuation: It should meet the design requirements, and generally should be less than.

ADSS optical cable is also known as all-dielectric self-supporting optical cable, that is, the material used in the optical cable is an all-dielectric (non-metallic) material, and the self-supporting means that the reinforcing components of the optical cable itself can bear its own weight and external load, and there is no need to erect steel strands. Since it is used on the power tower, it is necessary to have matching fittings to fix the optical cable on the tower.

ADSS Fiber Optic Cable Supporting Fittings]:

Tensile fittings: used in connection with terminal towers, tensile towers, towers with an angle greater than 25 ° and splice towers;

Hanging fittings: pre-twisted hanging wire clamps are connecting fittings that hang optical cables on transmission line towers;

Fasteners: realize the connection and installation of tension clamps and overhang clamps and towers;

Spiral anti-vibration device: interference-type anti-vibration device, which consumes the energy of the vibration of the optical cable and suppresses the vibration of the optical cable;

Splice box: It is the place where the end of the ADSS optical cable is connected;

Residual cable frame: used for placing surplus optical cables when the optical cable is connected;

Lead-down fixture: Fasten the ADSS optical cable from the tower or the optical cable on the tower so that it cannot shake to avoid the wear and tear of the optical cable.
