Hot dip galvanized yoke plates are a very common type of yoke plate product, mainly used to connect insulator strings, clamps, and tower supports to ensure the electrical safety and mechanical stability of power lines. What are the advantages of the hot-dip galvanizing production process? Compared with other surface treatment processes, the main advantages are as follows:
Corrosion resistance life: ≥20 years for inland use, and over 15 years for coastal use;
Cost: Hot Dip Galvanized Yoke Plates are relatively inexpensive, typically in the medium range, and considering their lifespan, they offer excellent value for money;
Tensile strength: Q355B ≥550MPa;
Process maturity: Globally standardized;
Maintenance cost: Low;
Mainstream structures: L-shaped, single-hole + double-hole, thickness 12–16mm, suitable for 110–220kV applications; rectangular yoke plate, multi-hole layout, thickness 16-20mm, suitable for 330kV double-string insulators; triangular yoke plate, as the name suggests, presents a triangular layout, thickness 20–25mm, suitable for tension section terminals.
When customizing hot dip galvanized yoke plates, please provide detailed drawings first. Based on the information contained in the drawings, the customized yoke plates will have higher precision. We require the following:
Drawing Requirements: The drawings must include the dimensions of the yoke plate, hole layout, material specifications, hot-dip galvanizing standards, and can indicate rated failure load, hole spacing, and thickness tolerances to ensure compliance with standards;
Delivery Method: We will send an electronic version via email or provide an online link for download;
Customization Requirements: If special dimensions or shapes are required, please communicate with the manufacturer in advance. Our company can also help you further refine the drawings to ensure the yoke plate specifications meet the requirements.
In which fields are Hot Dip Galvanized Yoke Plates used? When selecting them, we need to consider their advantages of high cost-effectiveness, high load-bearing capacity, and long-lasting corrosion protection, making them the first choice for corrosive environments. The main application areas are concentrated in the following aspects.
Industrial light corrosion scenario
Coastal power transmission lines more than 5km from the coastline adopt thickened zinc layer + passivation treatment, which can meet the service life of more than 15 years. Compared with 316 stainless steel, the cost is reduced by about 40%, and no additional coating treatment is required, making maintenance simpler. In the long term, the service life can be extended by applying zinc paint.
Wind power lines
such as the outlet line connection of wind turbine towers and the high-voltage side line of photovoltaic booster stations, these areas are exposed to wind, sand and rain and snow erosion. The galvanized layer can resist sand and dust abrasion and moisture corrosion, has strong adhesion and is not easy to fall off. Hot Dip Galvanized Yoke Plates are lighter than cast iron and stronger than aluminum alloys, and can withstand 10⁷ alternating load cycles without breaking.
Rural power grid renovation projects
With limited budgets, Hot Dip Galvanized Yoke Plates offer high cost-effectiveness. Compared to stainless steel and aluminum alloy materials, they can reduce procurement costs by 30%–50%. Rural power grid lines have relatively small loads, with a maximum load of ≤200kN, which can be fully met by hot-dip galvanized carbon steel. In addition, they are safe and convenient, which can improve work efficiency.
