1. The purpose of the tension clamp: The tension clamp is suitable for the ADSS optical cable tension rod and tower of the overhead line. The appropriate type of tension clamp is selected according to the ultimate tensile strength, running span and outer diameter of the ADSS optical cable. In order to ensure the integrity and reliability of the ADSS strain clamp function, in principle, the pre-twisted wire clamp can only be used for safe use once, and is generally not allowed to be used repeatedly. Unless it is only used as a “towing fixture” to tow the optical cable. In order to ensure good performance and personal safety, it is necessary to clarify whether the model and specifications of the fittings are consistent with the requirements of the optical cable before use.
2. Steps of installation method for strain clamp:
1. Align the outer wire installation mark with the optical cable to make the installation mark.
2. Align the installation mark of the inner wire end of the ** group with the optical cable and wind the ADSS optical cable.
3. The other groups of inner wire are operated in the same way as the ** group.
4. Install all the inner wires.
5. Align the outer wire installation mark with the inner wire installation mark.
6 Wrap one leg first, then wrap the other leg, wind the end of the outer wire, and the tension clamp is installed.

Tension clamps for carbon fiber wires, and today’s insulators are used in power, electrical communication cabinets, new energy vehicles, battery packs, lightning protection, wind energy machinery, frequency conversion equipment, and other related equipment. Each has its own requirements, but the installation method is the same. , It is also a special component required by the surrounding application environment of these industries. It mainly plays the role of fixed support connection and insulation, also called insulating spacer column.
In order to prevent the metal rod of the screwdriver from touching the skin or touching adjacent charged objects, an insulating tube should be put on the metal rod. When using a screwdriver to tighten or remove a live screw, do not touch the metal rod of the screwdriver with your hands to avoid electric shock accidents. Electricians are not allowed to use screwdrivers with metal rods running through the whole body, otherwise it is easy to cause electric shock accidents when using them. What safety knowledge should be possessed when using a screwdriver.
Mastering the method of distinguishing whether there is voltage is the key to electrical inspection. You can refer to the following methods for judgment. There is electricity due to the strong electric field of the working voltage, and the electroscope is close to the conductor-a certain distance, it will emit light (or alarm, indicating that the device has electricity. The closer the electroscope is to the charged object, the stronger the brightness (or sound). The operator carefully observes and grasps This is very important for judging whether the equipment is live. The equipment clamp introduces how to correctly distinguish whether there is voltage and what method to use to judge.
There should be enough bolts to withstand the pre-tightening force of the tension clamp. If considering the stress of the connecting plate and the hanging basket, the bolts on the connecting plate should be arranged vertically. But in such a package, the height of the basket must be higher. Especially when the cap beam load is large, more bolts are needed, and the height of the holding box will be larger, which will increase the hanging basket, and the excessively high hanging basket will also bring inconvenience to the construction. As long as the connecting plate of sufficient thickness is used and the necessary reinforcement plate is provided, the bolts on the connecting plate are generally arranged in two rows vertically. It is technically feasible and successful in practice. The economic benefits of the construction of cover beam 1 without support. When there is no foundation reinforcement, full support construction should be adopted, and the bottom seal beam foundation should be treated. When the load-bearing method is adopted, the installation of scaffolding only requires proper foundation treatment and does not require foundation reinforcement.
