Tension clamp is one of the most commonly used power line fittings. There are two kinds of cable tension clamp and wire tension clamp that are commonly used. Tension clamp is mainly used for corner, joint and terminal connection, is a fixed wire to withstand the tension of the wire and hang the wire on the tension string group or pole on the gold product. Tension clamps are roughly divided into two categories according to their structure and installation conditions:1. The tension clamp can withstand all the tension of the wire or lightning rod, and the clamping force of the wire clamp should be at least 90 times the rated tension of the wire or lightning rod to be installed, but it is not used as a conductor. This type of wire clamp can also be removed after the wire is installed and used for other purposes. This type of wire clamp has a bolt type tension clamp and a wedge type tension clamp, etc.2. In addition to withstanding all the tension of the wire or lightning rod, the tension clamp acts as a conductor. Therefore, this type of wire clamp cannot be removed after installation, so it is also called a wire clamp. Because it is a conductor, the installation of the wire clamp must comply with the provisions of the installation work procedures. The main function of the tension clamp is connection, protection and fixation.

Fuses can be divided into high-voltage fuses and low-voltage fuses according to the voltage used. According to the object of protection, it can be divided into fuses for the protection of transformers and general electrical equipment, fuses for the protection of voltage transformers, fuses for the protection of power capacitors, fuses for the protection of semiconductor components, fuses for the protection of motors and fuses for the protection of household appliances, fuses, etc. According to the structure, they can be divided into open-type fuses, semi-closed type fuses, tubular type fuses and spray type fuses. The open fuse has a simple structure, the melt is fully in contact with the air, and is supported by a porcelain column without support, which is suitable for outdoor use under low voltage. When the current is interrupted, a strong sound and light are generated in the atmosphere. The semi-closed fuse fuse is mounted on a porcelain frame and inserted into a porcelain box with metal sockets at both ends, which is suitable for indoor use with low voltage. When the current is disconnected, the generated sound and light are blocked by the porcelain box. The fuse tube melt is contained in the fuse body. Then connect it to the stand or connect it directly to the circuit for use. The fuse link is a completely sealed insulating tube with metal caps or contact plates at both ends. If the insulating tube of this fuse is filled with quartz sand, it will have the effect of limiting the current when breaking the current, which can greatly improve the breaking capacity, so it is also called a high breaking capacity fuse. If the tube is evacuated, it is called a vacuum fuse. If the tube is filled with SF6 gas, it is called an SF6 fuse, and its purpose is to improve the arc quenching performance. Since quartz sand, vacuum and SF6 gas have good insulating properties, this fuse is suitable not only for low voltage but also for high voltage. Jet fuses contain a melt in an insulating tube made of solid gas-forming material. The solid gas-forming material can be made of electrical anti-white cardboard or plexiglass. When the short-circuit current passes through the melt, the melt immediately melts to form an arc, and the high-temperature arc causes the solid gas-forming material to rapidly decompose to form a large amount of high-pressure gas, so that the ionized gas is ejected from both ends of the arc tube, emitting a strong sound and light. And when the alternating current crosses zero, the arc is extinguished and the current is interrupted. The insulating tube is usually mounted on an insulating bracket to form the entire fuse. Sometimes the upper end of the insulating tube is made movable, and after the current is disconnected, it is disconnected and discarded. This type of jet fuse is commonly known as a drop fuse. Generally suitable for outdoor use where the voltage is higher than 6 kV. In addition, fuses can be divided into general-purpose fuses, backup fuses and full-range fuses according to the breaking current range. The breaking current range of general-purpose fuses refers to the range from the overload current of more than 1.6-2 times the rated current to the maximum breaking current. These fuses are mainly used to protect power transformers and general electrical equipment. The breaking current range of backup fuses refers to the range from the overload current of 4-7 times the rated current to the maximum breaking current. This fuse is often used in series with a contactor. When the overload current is less than 4-7 times the rated current, the contactor is used to realize the breaking protection. It is mainly used to protect the motor.

1)High tensile strength of the clamp, reliable grip. The clamp strength is not less than 95%CUTS (calculated breaking force of twisted wire).2)The wire clamp evenly distributes the load on the stranded wire, does not damage the stranded wire, improves the vibration resistance of the stranded wire, and greatly extends the service life of the wire.3)Simple installation and easy construction. Can greatly reduce the construction time, without any special tools, one person can complete the operation.4)The installation quality of the wire clamp is easy to check, it can be checked with the naked eye without special training.5)Good corrosion resistance, the selection of high-quality materials. The material is completely consistent with the wire, which ensures that the wire clamp has a strong ability to resist electrochemical corrosion.6)The additional anti-theft ring effectively solves the problem of anti-theft.

There are several points to pay attention to when installing UT cable clamps:1. Apply grease to the threads before installation.2. There should be no obvious loose strands in the bent part of the rope. The broken end of the rope should be securely fastened to the main rope. The length of the tail rope protruding at the clamp should be three to five centimeters. After turning back, the tail rope should be securely tied to the main rope.3. The tongue plate of the cable clamp should fit tightly on the tension rope, and there should be no slipping after tensioning. The protruding part of the cable clamp is on the tail line side. Do not damage the wire strands during installation.4. Use 3.2 mm galvanized iron wire to tie the wire. The long end of the tying wire should have fifteen turns and the short end should have five turns. The tail wire of the tying wire should be twisted and tied firmly. Leave the short end of the tie line 25mm away from the line, and the tie line should be level and taut.5. After installing the nut on the UT type wire clamp, the protruding length of the screw thread should be one third of the total thread length. After tightening, the double nuts of the UT type wire clamp are tightened together.6. When using double clamps and connecting plates for the same group of cables, the direction of the ends should be the same.

A suspension clamp is a connecting device commonly used in power transmission lines, also known as a suspension clamp. It is mainly used to connect wires and suspension insulators to ensure the safety and stability of power lines. Suspension clamps are usually made up of a rope and clamps to withstand high tension. Hanger clamps mainly perform the task of connecting wires and suspension insulators by protecting the cables and clamping the clamps.In the transmission line, the tension and suspension of the cable are used to make the connecting line a balanced straight line. The clamp plays the role of fixing the wire to prevent it from swinging and shaking under strong wind and other conditions, thereby ensuring the safety and stability of the wire. Hanger clamps have a wide range of applications in power transmission, and can be used in high-voltage circuits, low-voltage circuits, and communication circuits. Among them, high-voltage circuits are the scenarios where hanger clamps are widely used. Hanger clamps are used to ensure the safety of transmission lines and the effective transmission of power signals. In order to ensure the safety and stability of the suspension clamp structure, it is necessary to pay attention to the following aspects.1. The quality and strength of the materials: Steel cables or steel bars are an important component of the suspension clamp structure, so it is necessary to use high-quality materials that meet certain strength standards.2. Structural design and installation location selection: The design and installation location of the suspension clamp structure should be approved and inspected by professionals to ensure the safety and stability of the structure.3. On-site construction management and supervision: The on-site construction should be carried out in strict accordance with the design plan and relevant standards, and strict quality control and safety management should be implemented.In short, the suspension clamp structure is very often used in modern architecture and plays an important role. As long as the design and construction are carried out in strict accordance with the relevant standards and the key points are mastered, the safety and stability of the structure can be guaranteed.
