How to choose the right PS Clevis?
Consider the following factors:
Load Requirements
The appropriate model should be selected based on the mechanical requirements of the application, especially for medium and low voltage applications and heavy-load lines.
01
Space Constraints
The size should be selected based on the depth and width of the installation location, making it suitable for compact spaces.
02
Connection Method
For right-angle connections, a closed-pin design is preferred to minimize the risk of loosening.
03
Material Standards
Hot-dip galvanized steel is suitable for general outdoor environments and offers basic corrosion resistance. Stainless steel closing pins are suitable for areas with high humidity and salt spray corrosion.
04
After selecting the appropriate PS Clevis, ensure proper installation to ensure proper operation.
Preparation
Confirm the cladding model and ensure it matches the nominal breaking load to project requirements. Check the integrity of the hot-dip galvanizing layer and the rust-proofing of the blind pins. Verify the specifications of bolts, screws, and other accessories. Stainless steel connectors are preferred for increased durability.
Positioning and Connection
Use a spirit level to calibrate the cladding mounting surface to ensure a vertical deviation of ≤2mm/㎡ to avoid uneven load distribution due to tilting. Secure the cladding vertically to the supporting structure with M12-M20 bolts. Use blind pins to lock the connection ends to prevent loosening due to electrical vibration.
Connector Assembly
When connecting single panels, align the combined relief grooves and rotate the opening and closing handle to lock the snaps together, forming a straight extension. Connecting single and double panels requires cascading, with welded mating sockets to enhance joint rigidity.
PS Clevis are key components for line connection and protection. They are used for assembling insulator strings and securing equipment on transmission lines. They can connect single brackets or double brackets. The right-angle design offers flexibility and adapts to various installation requirements.

They can connect single brackets or double brackets. The right-angle design offers flexibility and adapts to various installation requirements. They are commonly used in assembling suspension clamps and insulator strings. PS Clevis are manufactured from hot-dip galvanized steel with stainless steel closing pins to ensure corrosion resistance and structural strength. The specific size range varies depending on the model, making them suitable for various applications.
After installation, the PS Clevis should be inspected by applying a static load of 30% of the nominal load for 10 minutes. Observe for deformation of ≤1.5mm and check for abnormal noise at the connection points. After inspection, it can be used.
PS Clevis are used for hanging insulator strings, connecting guy wires, and extending tower structures in overhead transmission lines. They meet the right-angle connection requirements of components such as suspension clamps. Their enhanced welded structural design allows for expansion into the construction sector, primarily for securely securing components in non-power applications such as exterior wall brackets. They can also be used in the following areas:
Transmission Line Connections
Connecting suspension or tension insulators in series, compensating for installation length errors, replacing UB brackets, and connecting tension clamps to tower mounting points;
Substations
Adjusting the length of heavy busbar duct supports and distributing mechanical stress;
Industrial Expansion
As lightweight guy wire connectors.
