What tool is typically used to clean conductors prior to splicing?

The use of a wire brush to clean conductors prior to splicing is essential for ensuring a good electrical connection. Wire brushes are effective tools for removing oxidation, dirt, and other contaminants from the surface of conductors. This cleaning process is critical because even a small amount of contamination can impede electrical flow and lead to poor connections, which may cause overheating or system failures.

In contrast, while a cloth rag can wipe away some surface dirt, it is often not abrasive enough to remove oxidation effectively. Sandpaper may damage the conductor's surface, particularly in instances where it could remove too much material or create scratches that might impact conductivity. Although a solvent solution can clean surfaces as well, it typically does not provide the mechanical action necessary to remove tough oxidation from the metal surface, making it less suitable for preparing conductors for splicing.

Using a wire brush is widely recognized as a best practice in lineman procedures, ensuring that the conductors are properly prepared for a secure and reliable splice.
