The base material of the Rectangular Yoke Plates is entirely made of Q235 carbon structural steel, integrally formed by stamping, with no welded joints throughout the process. This structural design avoids the risk of fatigue cracking of welds under long-term alternating tension. Our standard models have a nominal breaking load range of 30kN to 200kN, corresponding to most line operating conditions from 10kV to 220kV. We have standard molds for mainstream specifications and also maintain a stock of in-stock items, eliminating the need for customers to wait for mold development for standard models. Replenishment orders and urgent orders can be produced and shipped quickly.
We consistently adhere to high standards in dimensional control. Hole diameter tolerances strictly follow H13 grade, and hole center deviations are controlled within 0.2mm. Every finished product undergoes a full-dimensional inspection before leaving the factory. Those who have worked on overseas projects know that many remote construction sites lack complete processing tools. If the hole positions don't match, it not only delays the project but also incurs high costs for temporary tool modifications. Our strict tolerance control ensures that the goods can be directly installed on-site with standard bolts and pins, eliminating the hassle of secondary processing. Plate thickness and hole spacing are manufactured according to general power fitting standards, ensuring high compatibility with mainstream international insulators and hanging ring accessories, eliminating the need for customers to adjust design drawings.
The lifespan of outdoor overhead fittings largely depends on the anti-corrosion process. These Rectangular Yoke Plates undergo a uniform hot-dip galvanizing surface treatment, strictly adhering to ISO 1461 standards. Each batch undergoes zinc layer thickness and adhesion testing, and each piece is inspected after plating; any missed plating, zinc nodules, or burrs are thoroughly cleaned. They can provide long-term stable service in typical inland outdoor environments. For highly corrosive environments such as coastal areas with high salt spray and industrial areas with acid rain, we also offer customized solutions with thicker galvanizing. Corresponding salt spray test reports are provided with the goods to meet the acceptance standards of different regions.
For special dimensions, hole positions, or material requirements, customers can provide drawings or detailed parameters for sample confirmation. Small-batch trial orders are also accepted without excessively high minimum order requirements. Tensile strength testing is conducted on each batch of goods before shipment. Material certificates and galvanizing test reports are sent with the goods. If customers require on-site inspection by third-party organizations such as SGS or BV, we can provide full cooperation, as all relevant qualifications and testing procedures are readily available.
Packaging is configured according to long-haul sea freight standards, with individual pieces separated by moisture-proof paper, reinforced with steel straps in fumigation-free wooden crates or pallets, and cushioned corners. Stacking weight is strictly controlled to prevent workpieces from being crushed or deformed.
For container loading, the model and quantity are checked item by item. All necessary documents for customs clearance, including invoices, packing lists, and certificates of origin, are prepared in advance and provided to the customer simultaneously with the shipment, ensuring timely customs clearance at the port.
For any questions regarding model selection, please provide the line voltage, rated tension, and specifications of the matching hardware. We can assist in matching the appropriate model. We can also provide quotations for matching hanging rings, U-shaped hanging plates, and adjusting plates, saving you the effort of dealing with multiple suppliers.
