Electrical yoke plate are primarily used to ensure the stability of core components such as insulator strings, conductors, towers, and clamps in overhead transmission lines, substations, and new energy power plants. They can be considered a bridge to ensure safe, stable, and efficient power transmission. Under the harsh operating conditions of the power industry, they can be adapted to 110kV-1000kV and above high-voltage, ultra-high-voltage, and extra-high-voltage transmission lines. During the production process, they have passed multiple authoritative certifications in the global power industry, meet mainstream international technical standards, and are exported to many countries and regions in Europe, America, Southeast Asia, the Middle East, and Africa.
In the production process, hot-dip galvanized carbon steel, namely Q235B and Q345B, is usually preferred for electrical yoke plates. These materials have excellent mechanical properties, ensuring a yield strength of ≥345MPa and a tensile strength of ≥510MPa. In addition, carbon steel has a lower cost, which can improve the cost performance of the product. It is the most widely used base material in the world.
From the image, we can see that the electrical yoke plate has an isosceles triangular structure. This shape accounts for more than 60% of the global market usage. The holes are arranged symmetrically to distribute the loads of the conductor's own weight, icing, wind force, etc., and can ensure safety redundancy under extreme working conditions.
Electrical yoke plates can be applied to power construction scenarios worldwide, especially in high-voltage, ultra-high-voltage, and extra-high-voltage overhead transmission lines, where they have been widely used. For example, cross-border transmission lines in Southeast Asia and the construction of extra-high-voltage power grids in Africa all use this type of yoke plate. It is used to fix conductors at conductor branches or, in conjunction with terminal clamps at the end of the line, to anchor the conductors to the towers, bear the tension at the end of the line, and prevent loosening and falling off.
Transmission lines in coastal areas or offshore wind power platforms are made of stainless steel that has been heated and galvanized to resist seawater salt spray corrosion, thus extending their service life. For transmission lines in high-altitude or cold regions, low-temperature forged steel can be selected to avoid low-temperature brittleness.
With its advantages of high strength, long-lasting corrosion resistance, and adaptability to various scenarios, coupled with flexible customization services, electrical yoke plates have become a core product for global power infrastructure. In the entire export process, we also have the following advantages:
Competitive advantages
Compared with some European and American brands, the price is 20%-30% lower for the same performance and quality, and it also supports customized services, providing complete solution design and quotation to meet the needs of overseas markets;
Trade adaptability
We use export-specific packaging that is moisture-proof, corrosion-proof, and collision-proof, with corrugated cardboard boxes and pearl cotton lining to ensure that the products are transported without damage. We offer multiple transportation options, including sea freight, air freight, and express delivery, to ensure fast delivery to users.
Service Support
Our company has a multilingual sales team that provides one-on-one dedicated support to resolve obstacles in cross-border communication. We provide user manuals, technical parameter sheets, installation guides, and customs codes in local languages to facilitate customs clearance, sales, and use for our customers.
The customized service for electrical yoke plates aims to precisely match the personalized needs of different voltage levels, installation scenarios, and extreme environments. From demand communication to final delivery, we ensure the adaptability, safety, and delivery efficiency of customized products.
Requirements submission
Key information must be clearly provided, including the required voltage level, applicable scenarios, connection objects, stress requirements, shape selection, hole parameters, main body dimensions, and installation compatibility. For the selection of substrate, surface treatment, and special processes, it should meet the actual working conditions. Order quantity and delivery cycle should also be communicated.
01
Solution Confirmation
Based on the user's needs, the hole layout, plate thickness design, and reinforcing rib layout are designed to ensure balanced force and no stress concentration. A 3D model and 2D engineering drawings are created to clarify details such as installation positioning marks and rated loads. Surface treatment process parameters are also specified to ensure that the corrosion resistance meets the standards.
02
Sample production
The samples are formed by CNC forging and stamping equipment, and the holes are machined by CNC boring machine. The dimensional tolerances are strictly controlled. The samples are galvanized and sprayed using the specified process to ensure that there are no defects such as missed plating, bulging, or peeling. The edges are rounded, the hole walls are smoothed, and the markings are engraved to ensure that the samples are consistent with the mass production standards.
03
Finished product inspection
Use a coordinate measuring machine to check key dimensions such as hole diameter, hole spacing, and plate thickness to ensure compliance with drawing requirements. Conduct tensile strength tests, impact tests, and salt spray tests. Check the uniformity of the galvanized layer, surface smoothness, absence of burrs, and clear markings. Provide a complete inspection report. For foreign trade clients, an English inspection report will also be provided.
