Analysis Of The Suspension Wire Clamp Boat-shaped Channel Structure: The Core Logic Of Wire Clamp Hull And Channel Design
The standard product of harga suspension clamp retains the U-bolt style, usually called a boat-shaped wire clamp, which is composed of three parts: the bracket U-bolt, the wire clamp hull and the pressure plate. The boat-shaped groove has a tapering, arc-shaped profile, with the groove bottom curvature matched to the conductor's outer diameter. This ensures that when the conductor falls into the groove, the contact surface forms a uniform arc-shaped fit, rather than localized point contact. This curved surface distribution disperses the clamping force along the conductor's axial direction, reducing the radial pressure exerted by the clamp on the outer strands of the conductor.
Structural Relationship between Hull Rotation Axis and Channel Type
messenger suspension clamp Based on the different positions of the rotatable points, they are divided into three types: center-rotating, pendant, and overhead. The rotation axis of the center-rotating cable clamp hull is located on the center line of the overhead line; the rotation axis of the bag-type (pendant) cable clamp hull is located above the center line of the overhead line; and the rotation axis of the overhead-type cable clamp hull is located below the center line of the overhead line. Its rotation often exceeds the deflection of the overhead line, and it has an unstable tendency, so it is only used in special occasions.
The position of the rotation axis and the orientation of the hull-shaped channel are geometrically coupled:
-
Center-rotation type: The center axis of the channel coincides with the rotation axis, and the hull rotates synchronously when the conductor deflects;
-
Dangling type: The center of gravity of the channel is lower than the rotation axis, the deflection response is delayed, and the structure is relatively simple to manufacture;
-
Top-mounted type: The rotation axis is lower than the bottom of the channel, the dynamic stability is weak, and the applicable scenarios are limited.
The suspension clamp with i hook channel design is not an isolated parameter, but rather forms a linked mechanical system with the hull rotation mechanism and the displacement range of the U-bolt. When the hull of the suspended clamp rotates to a certain angle, the U-bolt will be blocked by the bracket, forming a maximum deflection angle limit. This limit is directly related to the conductor diameter—the larger the diameter, the higher the U-bolt moves, and the smaller the maximum deflection angle. Therefore, the selection of the channel size must be considered in conjunction with the cross-section of the overhead line and the on-site wind deflection conditions.
