What is the purpose of injecting filler paste into the sleeve?

Injecting filler paste into the sleeve serves the primary purpose of preventing oxidation. When electrical connections, such as splices, are exposed to moisture and air, the metal components can oxidize, leading to increased resistance and eventual failure of the connection. The filler paste acts as a barrier, sealing the connection off from the surrounding environment, which significantly reduces the chances of oxidation occurring.

This protective measure ensures the longevity and reliability of the splice, allowing it to maintain optimal electrical performance over time. By keeping moisture and air out, the filler paste plays a critical role in safeguarding the integrity of electrical joints, which is essential in lineman work to ensure safe and effective power distribution.
