What preparations are needed before using the Z-1080 Clevis?
Quality Inspection
Check that the material is forged Q235B carbon steel and that the surface is completely galvanized, with a zinc coating thickness of ≥86μm. Observe for surface defects such as missing plating, peeling, and burrs.
01
Surface Verification
Measure the flatness of the tower's hanging plate installation site. The tolerance should be ≤3mm/2m. Exceeding tolerances require shimming or rework.
02
Lifting Equipment
Components weighing over 100kg must be lifted using lifting equipment. Manual lifting is strictly prohibited. The hook and hanging plate must be double-locked using connectors.
03
Supplementary Materials
Spare anti-loosening bolts, spacers, and neutral, environmentally friendly sealant for joint filling. Corrosive materials such as marble glue are prohibited.
04
The Z-1080 Clevis is suitable for transmission lines with voltage levels ranging from 10kV to 330kV. Different bracket types are selected for different voltage levels, so we must thoroughly understand the bracket's insulation performance and mechanical strength to ensure stable operation within the voltage range. To meet environmental requirements, the Z-1080 Clevis is forged from high-quality hot-dip galvanized carbon steel for corrosion resistance.

To meet environmental requirements, the Z-1080 Clevis is forged from high-quality hot-dip galvanized carbon steel for corrosion resistance. It is available in three- and four-leg configurations. Its slotted interface accommodates various hardware combinations, including suspension clamps and tension clamps. Insulators can be connected in series to form tension and suspension strings, ensuring even load distribution and ensuring optimal mechanical strength.
The Z-1080 Clevis is a connection fixture primarily used in power systems, specifically in the following areas:
Overhead transmission lines
Suspending insulator strings from tower crossarms or connecting insulators to tension clamps ensures stable overhead transmission of conductors and power.
Substations
Connecting busbars, jumpers, and insulators or other hardware, changing the direction of connections and securing them.
High-voltage transmission towers
Connecting directly to tower crossarms, they can also be used to connect other hardware, such as tension strings or jumper strings, creating a stable connection structure on the tower, ensuring the tower can reliably support conductors, insulators, and other components in various weather conditions.
Maintenance and Care for the Z-1080 Clevis
Appearance Inspection
Depending on the operating environment, inspect the hanging plate every six months to one year, checking for cracks, deformation, wear, and other mechanical damage. Cracks, which may lead to breakage, should be promptly replaced.
Connection Inspection
Verify the Z-1080 Clevis secure connection to adjacent hardware, check for loose, missing, or rusted bolts, and verify that the nut tightening torque meets design requirements.
Rust Removal
Clean surface contaminants such as dust, oil, and bird droppings. If rust is evident, remove impurities from damaged areas and repair any damaged areas.
Bolt Maintenance
Regularly inspect the connection bolts. Replace bolts of the same specification and strength if rust, thread stripping, or breakage is detected.
