Its square structure provides enhanced stability when connecting two split conductors. Its maximum design load capacity reaches 300kN, far exceeding that of synchronous coupling plates, making it suitable for branching structures in heavy-duty transmission lines. It is manufactured from Q235 carbon steel, hot-forged, and hot-dip galvanized to meet corrosion protection standards across various industries.
Both the LF-3040 yoke plate and L-shaped coupling plates are widely used in the industry. What are the differences between them?
Load Capacity
The L-shaped coupling covers low to medium-high loads and is used for assembling double or multi-strand insulator strings on conventional branch lines. The LF-3040 yoke plate has a load capacity of up to 300kN, which is considered high among couplings.
Applications
The L-shaped coupling is used for general-purpose connections between insulator strings and conductors or guy wires. The LF-3040 yoke plate is specifically designed for high-stress environments, particularly industrially polluted areas.
Applicable Applications of the LF-3040 yoke plate
Heavy-Duty Transmission Trunk Lines
Suitable for high-voltage environments of 110kV-500kV, especially in long-span, high-tension sections.
Coastal Corrosive Environments
Its corrosion resistance is superior to other models, verified by salt spray testing.
High-Load Environments
Heavy-duty connection points between multi-split conductors and insulator strings, capable of withstanding extreme mechanical loads.
While suitable for these extreme environments, maintenance and upkeep are required. The harsher the environment, the more important it is to shorten the maintenance cycle.
As a heavy-duty electrical connection fitting, what precautions should be taken when using the LF-3040 yoke plate?
Load Matching
Whether it's a high-load or low-load connector plate, ensure it matches the intended use environment to avoid overloading.
Environmental Adaptability
Different environments have different requirements for connector plates. For corrosive environments, the zinc coating thickness should be selected based on the environment to ensure long-term use.
Inspection
Before use, inspect the hole position accuracy, weld quality, and connectivity to ensure compliance.
