The triangular yoke plates we've discussed all present a triangular structure in appearance. However, different models vary significantly in their hole layout, stress structure, installation method, and functional application. Therefore, yoke plates are not interchangeable or universally applicable in many scenarios. The main difference in the triangular structure lies in the presence of one main hole at the apex, two symmetrical holes at the base, and an overall isosceles triangular distribution. The advantage of this structure is its symmetrical and unbiased stress distribution, providing excellent resistance to torque and wind vibration during use, making it suitable for use in global power projects.
Triangular yoke plates are core components in high-voltage transmission lines, effectively ensuring the stability and safety of the transmission system. They play a crucial role in global power projects, particularly overhead high-voltage transmission lines, and have received unanimous recognition from users.
During the production of triangular yoke plates, we prioritize product quality, ensuring durability and reliability. Therefore, we preferentially use ductile iron, which not only possesses excellent mechanical properties but also high tensile strength and toughness. Its performance is unaffected by long-term tensile stress and vibration in power lines, further ensuring the precision of the overall structure. For high-load applications, forged steel can also be selected. Through precision forging and heat treatment, it features a precise internal structure free of porosity and cracks, with a rated breaking load of up to 600kN, meeting the requirements of heavy-load transmission.
The finished triangular yoke plates undergo rigorous anti-corrosion treatment, allowing them to be used even in rain, snow, and humid environments. The main anti-corrosion process is hot-dip galvanizing, which conforms to international standards such as ASTM A153 and GB/T 13912. The zinc layer thickness is ≥85μm, ensuring that the zinc layer has sufficient adhesion to isolate the yoke plate from the external environment, thereby preventing corrosion.
The triangular yoke plate is a core component in industrial connectors, playing a vital role in fields such as machinery manufacturing, power equipment, and construction. Through precise hole spacing and diameter design, the bolts and pins are matched, achieving both strength and durability.
Hole spacing design
For mechanical assembly scenarios requiring precision positioning, a small hole spacing, typically around 10mm or 15mm, can be selected to ensure a tight fit between the connecting parts, thereby reducing vibration and displacement. For applications requiring large structural components, a large hole spacing, typically 30mm or 50mm, is required to improve work efficiency.
Aperture Design
For M6 bolts, we can design a 6.5mm hole diameter, and for M8 bolts, we can choose an 8.5mm hole diameter. This can be matched with different fasteners. During the production process, high-precision drilling machines and grinding machines are used to ensure that the roundness and perpendicularity of the hole diameter reach the best state.
