ADSS (All-Dielectric Self-Supporting) optical cable is an optical communication cable used to transmit optical signals. It can be used for communication transmission of transmission towers, transmission lines, etc. From the perspective of installation and construction acceptance, the installation steps, precautions and acceptance criteria of ADSS optical cable are as follows:
Planning and design: First of all, it is necessary to plan and design the optical cable according to the situation of the power line, and determine the installation position, installation height, tension and other parameters of the optical cable.
Material preparation: According to the planning and design results, prepare the required optical cable materials and installation accessories, such as optical cables, optical cable joints, tension towers, jumpers, etc.
Install the optical cable: Use a crane to pull the optical cable to the installation position, fix and fix it according to the design requirements
Tension adjustment to ensure that the installation tension of the optical cable is within the allowable range.
Make a jumper: Install a jumper to fix the connection point between the optical cable and the cable.
Install the connector: install and debug the optical cable connector at the position where the optical cable connector needs to be installed.
Test: After the installation is completed, it is necessary to use a professional optical cable tester to test the performance of the optical cable to ensure that the transmission performance of the optical cable meets the standard requirements.
Installation steps：
(1) Determine the installation path and length of the cable, calculate the tension of the cable and the installation location of the tension auxiliary facilities.
(2) Install hanging wires at the beginning and end of the cable line to bear the weight and tension of the cable.
(3) Set tensioning auxiliary facilities on the cable line as required, such as tensioning rings, protective sleeves, etc.
(4) Pull the cable from the fixed point of the suspension wire at the starting point to the fixed point of the suspension wire at the end point, and fix it on each tensioning auxiliary facility.
(5) Set a protective sleeve and tensile auxiliary facilities at the elbow of the optical cable to protect the tensile strength and optical characteristics of the optical cable.
(6) Suspend and adjust the tension of the steel cable to ensure that the tension is evenly distributed.
(7) Insulate and ground the cable to ensure its safety and reliability during use.
Precautions
(1) During the installation of the optical cable, care should be taken to avoid twisting and damaging the optical cable, thereby reducing its optical characteristics.
(2) During the suspension process of the cable, attention should be paid to the even distribution of the cable tension to avoid excessive or insufficient tension.
(3) In the setting of the cable protection sleeve, attention should be paid to the selection and installation position of the protection sleeve to ensure the safety and reliability of the cable during use.
(4) In the insulation and grounding treatment of cables, attention should be paid to the selection and installation position of insulating materials and grounding facilities to ensure the safety and reliability of cables during use.
ADSS optical fiber cable is a common high-voltage power line optical cable, and the following problems may be encountered during installation and construction:
Installation height issue: ADSS optical cables are usually installed above the center line of high-voltage power lines, and attention should be paid to the accuracy of the installation height, otherwise the performance and safety of the optical cable will be affected.
The problem of too close distance: ADSS optical cable needs to keep a certain safe distance from the high-voltage power line to avoid the performance degradation of the optical cable due to the electromagnetic field interference of the high-voltage power line.
Installation tension problem: The installation tension of ADSS optical cable needs to be controlled within a certain range, too high or too low will affect the performance and life of the optical cable.
Anti-corrosion of optical cables: ADSS optical cables installed in humid or corrosive environments need to have high anti-corrosion performance, otherwise the life of the optical cables will be shortened.
Acceptance Criteria：
In order to solve these problems, we need to carry out reasonable planning and design, select the appropriate optical cable model and installation scheme, and ensure the safety and stability of the optical cable. At the same time, it is also necessary to carry out professional on-site construction and testing, follow relevant safety regulations and operating procedures, and ensure the safe construction and acceptance of optical cables.
After receiving the ADSS fiber optic cable goods, we need to carry out the following acceptance criteria:
1. Appearance inspection: Check whether the appearance of the optical cable is intact, whether the packaging is tight, and whether the moisture-proof performance is good.
2. Check the length of the optical cable: Check whether the length of the optical cable meets the requirements of the order, and whether it is too short or too long.
3. Optical cable material inspection: Check whether the optical cable material meets the specification requirements, such as optical fiber, protective layer, casing, etc.
4. Optical cable performance inspection: Conduct performance tests on optical cables through optical cable testers and other equipment to check whether the transmission performance and loss of optical cables meet the standard requirements.
5. Packaging label inspection: Check whether the label on the optical cable package is clear and complete, and whether it meets the order requirements.
In a word, during the installation and acceptance process of ADSS optical fiber cable, careful inspection and standardized operation are required to ensure the performance and safety of the optical cable.
