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.

DTL series copper-aluminum terminal blocks are suitable for transitional connection between aluminum-core cables of power distribution devices and copper ends of electrical equipment.
The use of copper-aluminum transition terminals is because of the characteristics of the material, the connection between copper wires and aluminum wires is easy to produce an oxide layer and generate resistance, causing high temperature to burn or power off the joints, so in order to eliminate the situation of manual connection, the copper-aluminum transition terminal terminals to avoid.
Compared with other cold-pressed terminals, DTL copper-aluminum transition terminals will be lower in price due to different materials, and the cost performance is still very good. If the requirements for conductivity are not high, copper-aluminum transition terminals can be used to save costs.
The copper-aluminum transition wire nose is made of L3 aluminum and T2 copper material. It is made of friction welding process and has high weld strength. The main application range is various circular and semi-circular fan-shaped aluminum The transitional connection between the cable and the copper end of the electrical equipment. It has the characteristics of good electrical performance, resistance to galvanic corrosion and long service life.
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.
We have passed the above steps, the production of electric power fittings will be completed. In the above process, there is a certain dependence between the various steps, and each step has its own process details and operational points, which need to be carefully controlled and managed. Only in this way can we ensure the production of high-quality, high-performance power fittings products.
Wire widely used iron or aluminum metal accessories, collectively referred to as goldware. There are many kinds of hardware, different uses, for example, various wire clips for installing wires, various hanging rings for making up insulator strings, various pressure tubes for connecting wires, repair pipes, various types of spacers on split wires, etc., in addition to various types of wire pulling hardware for poles and towers, and used to protect the size of wires, which must be coordinated with each other.
Most of the hardware needs to withstand a large tensile force in operation, and some also need to ensure good electrical contact, which is related to the safety of the wire or tower, even if one is damaged, it may cause line failure. Therefore, the quality, correct use and installation of the hardware have a certain impact on the safe transmission of the line.
