Prevention Of Sharp Angles In Wedge-shaped Tension Wires: Product Lifespan From The Perspective Of Casting Process

To improve the operational stability of power distribution projects, many teams focus on post-maintenance. However, experienced technicians know that the root of problems often lies in the manufacturing process. As a core component for securing the conductor, if the fiber optic dead end clamp has a "sharp corner" defect, it is very easy to generate corona discharge after being energized.

The Decisive Role of Mold Precision in Burr Control

Often, tiny protrusions or sharp edges on the surface of the clamp are often a consequence of mold aging or improper mold closing. These physical defects act like tiny needles in a strong electric field.

• Cavity Polishing Process: High-frequency use requires the mold's inner wall to achieve mirror-like flatness.

• Precise Gating Gate Treatment: Residual protrusions after gate removal are a high-risk area for sharp corners.

• Uniformity of Release Agent: Uneven application can obstruct the aluminum alloy flow channels, leading to serrated wrinkles on the molded edges.

Relationship between surface smoothness and electric field distribution

If the body or pressure plate of fixed dead end clamp has sharp edges that are difficult to see with the naked eye, the local potential gradient will be instantly increased. This physical defect directly changes the originally uniform charge distribution. Under long-term high-voltage conditions, these tiny sharp points will accelerate the deterioration of the surrounding insulation medium. Only by eliminating these geometric irregularities in the early stages of production can the connection points on the power poles and towers be made more durable.

Balancing Mechanical Performance and Electrical Protection

Optimizing the external profile of the dead end clamp, while ensuring grip strength, is a major trend in technological upgrades. The quality of details such as the chamfering radius of the edges and the smoothness of the bolt holes directly affects the noise control of the entire line. Many engineering companies now report that clamps with rounded appearances and smooth touches have a much lower failure rate after being connected to the grid than those with rough workmanship.

Deep Polishing in the Final Stage

Every finished ab cable dead end clamp clamp must undergo high-intensity tumble polishing or manual fine grinding before leaving the production line. This physical "de-sharpening" treatment aims to address the issue of residual scrap material that cannot be completely eliminated during the casting process. It ensures that every corner of the metal component has a natural, rounded transition. This is not only for aesthetics but also to reduce the probability of point discharge in windy or humid weather, giving the power grid more reliable operation.
