How to control the speed of self made construction optical cable pay off

Adopt guide pulley, that is, the hanging wire is put into the pre-installed hanging wire groove along the end of a terminal, and a large pulley is installed at the other end of the pole part, and the hanging wire is tightened by using the take-up machine or the hoist after changing the direction.

When laying the optical cable, one small guide pulley should be installed every 20 30 meters, and the rope should be drawn through the pulley in order until the end of the optical cable is reached. In construction, the fiber optic cable is generally towed several times.

After the cable traction is completed, the optical cable is hung on the hanging line with a hook at one end or several ends at the same time, which is usually used (the engineer takes the scooter to operate faster and better). Other methods can also be employed. When hanging the line, if it is a long-distance trunk line, due to the consideration of its certain distance, leave an appropriate residual coil tied and hung on the pole road, so that under special circumstances, the line is easier to recover.

Safety technical measures:

1. The walkie-talkie should be checked before use to ensure that the communication is clear and smooth during construction, and a special person is responsible for timely charging.

2. After the tow rope is off the ground, the traction should be stopped, and after checking along the line, it is confirmed that there is no one on the line, no attachments are hanging, and no obstacles are hooked, etc., and then continue to pull and lift off, and when the tow rope is unfurled, it is strictly forbidden to pass under the live line.

3. In order to ensure the safety and feasibility of the connection of the braided sleeve, after the optical cable is inserted, a special person must be responsible for the binding.

4. When the optical cable is unfolded, the pay-off tension should be adjusted according to the regulations.

5. When hanging and unloading the wire lifting tools and disassembling the pay-off pulley, strictly prevent the fiber optic cable from being bruised. The pay-off pulley shall not be directly relaxed by people, but shall be relaxed by anchor piles or towers, and the binding shall be firm when lifting the tool materials, and no one shall be under the line.

6. When the accessories are installed, the appliance should be prevented from abrasion of the wire, and the working range and the lifting point of the optical cable should be protected by an open hose.

7. When installing the tension clamp and the clamping chuck, the optical cable must be forbidden to be folded at the point.

8. When the optical cable is unfolded, it is forbidden to drag the optical cable on the ground, and the end of the optical cable is forbidden to fall to the ground to prevent moisture.

9. It is necessary to strengthen the monitoring of the anti-twisting hammer along the line, and the traction speed of the anti-twisting hammer must be slow when passing the pulley, and at the same time, it is necessary to prevent the anti-twisting hammer from hooking the crossing frame, trees, etc.

10. Grounding measures must be taken before the installation of OPGW accessories for optical cables (including the operation of optical cables during construction). Workers must install security grounding wires before they can carry out construction work.

Depending on how your frame is made, it is generally a single caretaker who uses wood as a brake.

If you have done the wiring of ** lines before, it will be easy, almost.

Pull the steel wire between the poles first, hang the fiber optic cable on the steel wire, and hang a hook to the steel wire every half meter to one meter. When it comes to the pole, the radius of the bending of the optical cable is too small, generally more than 60 cm, so wind more and set aside. When pulling up the cable, pay attention to the bending radius should not be too small, otherwise the cable will be damaged.
