Strain Triangle Yoke Plate with different specifications and parameters has different applicable fields. Below we will introduce the mainstream yoke plate parameters. Users can choose according to the usage scenario.
| parameter | Specification | Application scenarios |
| ultimate tensile strength | 40,000-60,000 lb | 110kV-500kV medium and high voltage lines |
| Plate thickness | 19mm(3/4in)-25mm(1in) | Suitable for different tension levels, thick plates correspond to high tension |
| Aperture | 22mm-32mm | Match the connecting bolt specifications of insulators and clamps |
| Material | Hot-dip galvanized steel, ductile iron, aluminum alloy | Steel and ductile iron are used for high pressure and high tension, and aluminum alloy is used for lightweight scenarios. |
| surface treatment | hot dip galvanized | Anti-corrosion, suitable for harsh outdoor environments, optional double anti-corrosion in salt spray areas |
When we select the Strain Triangle Yoke Plate, we must not only match the line tension requirements, but also determine the specifications and application scenario working conditions of the connecting hardware to ensure that the selected yoke plate can safely carry the load and stably connect the components. The selection process is as follows:
Calculate line tension: Tension is the core indicator for determining the yoke plate. It is calculated based on the conductor model, cross-sectional area, unit length weight, etc. In addition, the ice thickness, wind speed level, line spacing, and local meteorological conditions must also be considered. If the maximum calculated tension of the conductor is 20kN and the safety factor is 2.5, the rated strength of the joint plate must be ≥50kN;
Matching strength: Common strength levels are 30kN, 40kN, 60kN, 80kN, 100kN, 120kN, 160kN, 200kN. The strength should not be lower than the calculated demand value, and long-term overloading should be avoided to cause breakage. The margin should not exceed 50% of the demand value. Excessive strength will also increase the cost and installation difficulty;
Specification parameters: Ensure that the connection dimensions are completely matched, including bolt hole diameter, hole spacing and hole location layout, plate thickness and overall dimensions;
Comply with execution standards: For the selection of Strain Triangle Yoke Plate, standards are also very important. The standards of different countries and regions vary greatly. Foreign trade selection must match the execution standards of the customer's region to avoid inconsistency in standards.
The selling points of Strain Triangle Yoke Plate mainly focus on stable structure, strong load, wide adaptability, long life, etc. It is suitable for high voltage, power distribution, wind power and other scenarios. For foreign trade scenarios, we can meet multi-national standards and support customized production. The main advantages are as follows:
Safe load-bearing
The three-point force design can decompose transverse and longitudinal tension. The torsion resistance and eccentric load resistance are significantly better than that of the rectangular yoke plate. It is suitable for high tension conditions such as tensile strength, terminal, and corner. The rated tensile strength is 30-200kN. It can be used in many fields. The aperture tolerance is ±0.5mm, which can improve the efficiency of on-site installation;
Value of use
Carbon steel + hot-dip galvanized material has a moderate cost and can be used in a wide range of applications. If you want a lightweight design, you can choose aluminum alloy material, which can reduce weight by 30%-40%. The anti-corrosion process can reduce corrosion and replacement frequency. The maintenance cost is 40%-60% lower than ordinary yoke plates. It is especially suitable for use in remote areas and cross-sea lines;
Customization ability
In order to make Strain Triangle Yoke Plate meet the needs of different working conditions, customization is also essential. It can be customized according to the customer's insulator, wire clamp hole diameter, and hole spacing. It is suitable for special installation spaces. For extreme application environments, anti-corrosion solutions such as galvanizing + passivation can also be provided, and anti-fatigue strengthening treatment can be added for high vibration scenarios.
