What Are The Performance Characteristics Of The Z-0780 Clevis?
Structural Features
Long-stem bolts form a front-to-back rotation axis, supporting dual shear loads. The slotted connection structure provides a left-to-right rotation axis, with the two axes at right angles to each other, enhancing flexibility.
Connection Stability
The bolt's dual shear surface design resists wind vibration and icing loads.
Suitability
It connects tension clamps to insulator strings and serves as a guying fixture to anchor pole towers, enhancing the structure's anti-overturning capacity.
Here's the installation process for the Z-0780 Clevis. First-time users are encouraged to take notes:
Pre-installation Preparation
Use a torque wrench, laser level, lock washers, and matching bolts to check the integrity of the Z-0780 Clevis zinc coating and ensure the hole walls are free of wear.
01
Positioning and Securing
Use a long-shank bolt to penetrate the upper hole of the bracket. Align the double shear surface with the crossarm connection surface. Align the lower notch of the bracket with the insulator ball head. Insert the pin and tighten, ensuring the left and right rotational axis is flexible.
02
Freedom Adjustment
Manually test the front and rear rotational axis and the left and right rotational axis to confirm that there is no binding during 90° rotation. Adjust the bolt tension to accommodate ±3mm deviation in the rigid busbar installation.
03
Strength Protection
Use a torque wrench to apply pressure in stages up to 100 N·m. Install lock washers to prevent loosening due to wind vibration.
04
Load Testing
Apply a static tensile force of 70 kN to check that the connection points are free of displacement and deformation.
05
The Z-0780 Clevis is a right-angle connector. Its two plates are perpendicular to each other, allowing for flexible changes in transmission line direction during operation. It is typically manufactured from Q235 or forged cast iron, formed by stamping and then hot-dip galvanized to meet C4 corrosion protection, meaning the zinc layer thickness must be ≥85μm. It measures approximately 70mm and weighs approximately 0.6kg, suitable for applications with a rated breaking load of 70kN.

The Z-0780 Clevis has become a mainstream choice for medium and low voltage transmission lines due to its standardized design, cost-effectiveness, and environmental adaptability. Especially suitable for 10kV to 110kV lines, the two lugs intersect perpendicularly and are compatible with ball-head hanging rings or bowl-head hanging plates, achieving a rigid connection between the insulator string and the tower. Users can choose a standard model based on their specific working conditions. For special models, our company supports custom orders based on sample requirements. Our priority is always the user.
