What coating is often used to fill the outer splice to prevent oxidation?

Zinc Chromate is commonly used as a coating to fill the outer splice due to its excellent properties that help prevent oxidation. This compound serves not only as a corrosion inhibitor but also provides a protective barrier against moisture and environmental elements that can lead to rust and degradation of metal components. The effectiveness of Zinc Chromate stems from its ability to form a stable adhesive bond with the metal surface, ensuring long-lasting protection.

In applications like electrical splicing, where exposure to air and moisture can rapidly lead to oxidation, using a coating like Zinc Chromate is crucial. This is especially important for maintaining electrical integrity and reliability in lineman work, where spliced connections must remain secure and conductive over time. The other coatings mentioned do not have the same level of effectiveness in providing long-lasting corrosion resistance in outdoor or harsh environments typically encountered in electrical work.
