Z-12100 Clevis

The main body of the product is made of high-quality Q235 carbon steel plate, stamped and formed with an integral bending structure. There are no splicing welds in the stress area, effectively eliminating the risk of stress cracking under high-altitude tension. Standard dimensional parameters are stable and uniform; plate width 24mm, matching bolt specification M22, total height 100mm, and single piece weight approximately 1.16kg. The mass production process precisely controls plate thickness, hole concentricity, and plate surface flatness, ensuring excellent interchangeability within the same batch. The unique Z-shaped bending structure allows for 90-degree right-angle rotation during assembly, adapting to the connection requirements of different angles between tower crossarms and insulator strings. It allows for slight free rotation during installation, accommodating on-site misalignment adjustments and significantly reducing assembly difficulty.

In engineering applications, the Z-12100 is a typical plate-to-plate connection hardware, primarily using high-strength bolts or pins to achieve rigid connections with other hardware. It is widely used in 10kV to 500kV overhead transmission lines, its main function being to scientifically combine insulators, suspension clamps, tension clamps, and various protective hardware to construct a complete line stress system. Its unique Z-shaped right-angle structure design ensures reasonable stress distribution and avoids stress concentration while also balancing compact installation space and ease of construction.

Power fitting connection methods are mainly divided into three types: ball-and-socket connections, ring-and-chain connections, and plate-to-plate connections. The plate-to-plate connection method represented by Z-12100, with its extremely high structural stability and tensile strength, has become the preferred choice for tension strings and important load-bearing nodes. In actual construction, relevant power construction specifications must be strictly followed to ensure tight connections and flexible rotation between hardware components, avoiding unnecessary bending moments on bolts due to improper installation.

Given the importance of hardware in power grid operation, quality control of this product should be implemented throughout the entire process of procurement, transportation, and installation.

Procurement and Acceptance: Before warehousing; the product quality certificate should be verified, and the appearance should be checked for defects such as cracks, sand holes, and zinc coating peeling. Key dimensional tolerances should also be verified.

Installation: During installation, it is essential to ensure accurate alignment of the connection holes and that the bolt tightening torque meets design requirements. The matching cotter pins must be installed in place and the tail split open to prevent them from falling off due to vibration. The use of wire or other substitutes to replace the dedicated cotter pins is strictly prohibited.

Maintenance and Repair: During regular inspections, special attention should be paid to checking the connecting rings for deformation, electrical burns, and corrosion, especially the wear condition of the connection points. Any problems found should be addressed immediately by replacing the affected parts.

Our factory maintains a year-round stock of Z-12100 standard connecting rings and also undertakes custom processing of various non-standard steering plates. We can adjust the plate thickness, opening size, bending angle, and galvanized layer thickness according to customer construction drawings. Our products are packaged with rust-proof paper, moisture-proof bags, and hard cardboard boxes for layered protection. We cater to both domestic bulk deliveries for engineering projects and long-distance sea freight for international trade. Each shipment includes a material certificate, mechanical tensile test report, and factory certificate of conformity, meeting all requirements for domestic project acceptance and overseas customs clearance. We welcome domestic and international power engineering companies and hardware export buyers to consult and discuss business opportunities with us, bringing drawings or physical samples.
