According to the main performance and use of the hardware, the hardware can be roughly divided into the following categories
1), suspension hardware, also known as support hardware or suspension clamp. This kind of hardware is mainly used to hang the wire insulation substring (mostly used for linear poles) and hang the jumper on the insulator string.
2), anchoring fixtures, also known as fastening fixtures or wire clamp. This kind of hardware is mainly used to tighten the terminal of the wire, so that it is fixed on the wire insulator string, and is also used for the fixing of the lightning rod terminal and the anchoring of the cable. Anchor fixtures bear all the tension of wires and lightning arresters, and some anchor fixtures become electrical conductors
3), connecting hardware, also known as hanging parts. This kind of fittings is used for connecting insulator strings and fittings to fittings. It bears mechanical loads.
4), continuation of gold tools. This kind of hardware is specially used for connecting various bare wires and lightning arrester wires. The connection bears the same electrical load as the wire, and most of the connection fittings bear all the tension of the wire or lightning rod.
5), protective equipment. This kind of equipment is used to protect wire, insulator, etc., such as the pressure balancing ring for protecting insulator, the heavy hammer for preventing the pulling of insulator string, and the anti-vibration hammer and wire protection bar for preventing the vibration of wire
6), contact with hardware. This kind of hardware is used for hard bus, soft bus and electrical equipment to be connected to the wire terminal, the T connection of the wire and the parallel connection of the non-bearing wire, etc. These connections are electrical contacts. Therefore, high electrical conductivity and contact stability of contact fixtures are required.
7), fixed fixtures, also known as power plant fixtures or high current bus fixtures. This kind of fixture is used for fixing and connecting various hard or soft busbars and pillar insulators in power distribution devices. Most of the fixed fixture is not used as a conductor, but only plays the role of fixing, supporting and suspending. However, since these fittings are used for high current, all components should have no hysteresis loss.
Yoke plate is a type of string hardware used for coupling the electrical clevis and the insulators or the socket tongue on the transmission line. During the yoke plate installation process, the insulators that are connected to the cross arm will be on one side and the conductor termination is on the other side.
Yoke plates can be made of carbon steel, ductile iron, forged steel and aluminum alloy. When it comes to the construction, a yoke plate is usually made high-grade steel carbon. This material is relatively thick enough to give it enough strength. The tensile strength of the material shields it from breaking of undergoing structural damage. The powerline fitting is designed to have a high rated breaking strength(RBS).
Still, in terms of the construction, the material for the yoke plate is hot dip galvanized. This coating protects against corrosion and rust. Water and chemicals that come into direct contact with the yoke plate won't cause any degradation. The surface of the yoke plate is smooth and does not have lumps.
For the design, the most common shape of the yoke plate is the triangular yoke plate. This shape is considered universal as it can easily fit into a wide range of applications.
However, there are other shapes for this overhead line accessory. You can find a rectangular yoke plate and even an irregularly-shaped yoke plate. So, when buying a yoke plate, you should specify the design or shape that you want. Of course, the choice of the shape will depend on your area of application.
Yoke plates have grooves or holes through which connections are made. The diameters of these holes tend to vary. This means that you need to be more specific with the size of the holes that you want.

L-shaped joint plate assembly Matters needing attention:
1. Pay attention to the direction hole, and coordinate with the cross-arm member of the tower.
2. The compensation length (L=b·sinθ/2) should be considered for the two hanging points.
3. Pay attention to vertical, horizontal and longitudinal loads when selecting U-bolts.
4. It is not advisable to use upper-rod suspension clamps for going up and down hills and crossing crossings.
5. The chemical influence should be considered for the joints of two different metals, and steel-aluminum joints are generally used.
Sixth, the strength should match the large use stress of the wire, especially the first fitting.
7. Pay attention to the cooperation between the ball and the ball socket.
8. When choosing fittings, the damage strength should be considered in the suspension clamp, and the grip strength should be considered in the tensile and splicing fittings.
First, Material selection and screening.
1. According to the functional requirements and use conditions of power fittings, select high-quality metal materials that meet the standards, such as carbon steel plate, stainless steel plate, copper plate, etc.
2. Strict screening and inspection of the selected metal raw materials to exclude unqualified materials and ensure reliable quality.
Second, processing and forming.
1. Develop the processing plan and process flow of the hardware, select the appropriate machine and equipment for cutting, stamping, bending and other processing operations, and accurately control the size, Angle, pressure and other parameters.
2. According to the requirements of different types of goldware products, the corresponding molding process is used, including rolling, casting, forging, welding, etc., to ensure that the product structure is tight and not easy to deformation.
Third, surface treatment.
1. Surface treatment of the formed fittings, including rust removal, grinding and other processes, to achieve the requirements of finish and anti-corrosion effect.
2. Select appropriate surface treatment methods, such as galvanizing, spraying, electrophoresis, etc., to enhance the corrosion resistance and beauty of the surface of the hardware.
Fourth. Assembly and inspection
1. According to the product design requirements and process flow, the assembly and combination of fittings are carried out, and the connection and functional performance of each part are strictly checked to ensure that the fittings have a reliable working state.
2. Inspect the finished products, including appearance inspection, pressure performance test, mechanical performance test, etc., to ensure that the products meet the requirements, and make the unqualified products be recycled, repaired or eliminated.
