Fiber Cable Manufacturer
First determine the tower number passed by each cable, especially the tower number of the starter tower and the end tower, and put the traction rope and pulley on each tower, then place the tractor at the starting tower, and place the optical cable disk and tension machine at the end of the tower. At the drape point in the middle of the span, the pulley diameter must not be less than 12 inches, and the pulley should not be less than 20 inches or 40 times times the cable diameter if the circuit condition changes significantly (such as the horizontal or vertical angle of 25 degrees or greater), and the pulleys used at the beginning and end of the line. Elastic rubber should be used as cushioning material in the pulley groove to reduce the wear of the outer sheath of the cable. The turn angle and the angle of the optical cable should be less than 30 °, the tension of the cable should be less than 1 tons, the speed of the cable should be 3-8 km/h, and the cable and the traction rope should be connected by the rotary compensation buckle to prevent the fiber optic cable from being cut to the stress due to distortion in the cloth release process. After the cable is towed to the end tower, the tension and sag of each tensile section are adjusted paragraph by Segment (the adjustment of tension and SAG should begin at one end of the whole line until the end of the other side of the line, the direction of adjustment should be the opposite of the direction of the installation of the optical cable to ensure the maximum use of the optical cable) and install the lead fixture, and finally the remaining cable plate to wait for the continuation.
In the process of putting the cable, it is important to note: The fiber optic cable must not be scratched with the tower body, if found that the optical cable skin has been scratched, should immediately stop construction, until the problem is resolved before continuing.
