Why Does The Cleaning Surface Need To Cover And Groove The Entire Length Of The Clamping Area?

When laying parallel groove clamp, the clamping points are distributed along the entire contact surface between the conductor and the clamp. If the cleaning surface only covers a portion of the length, the uncleaned areas may contain oxide layers, corrosion products, grease residue, or fine particles, all of which can affect the electrical and mechanical contact between parallel groove connector and the conductor. Covering the entire length of the cleaning surface during installation improves the uniformity of the contact surface, facilitating stable metal-to-metal contact between the conductor and the clamp during aluminium pg clamp clamping.

Furthermore, complete cleaning surface coverage supports later inspection and maintenance of the wiring process. If a section of the cleaning surface is neglected, slack or gaps may appear from that point when bimetal pg clamp is subjected to load, conductor vibration, or temperature changes. Covering the entire length of the blackburn parallel groove clamp clamping area with the cleaning surface helps the installation unit quickly identify potential hotspots or contact anomalies during subsequent inspections.
