A zinc sleeve is typically made by casting and is usually silver-colored.
The zinc sleeve is an essential component that ensures the long-term reliability and performance of high-voltage glass insulators, especially in challenging environmental conditions with high levels of pollution and corrosion.
The primary function of the zinc sleeve is to prevent the removal of ions from the insulator, providing a lower potential than the forged steel pin and protecting the insulator from corrosion.
The zinc sleeve is a critical component of certain high-voltage glass insulators, serving to protect the insulator from corrosion and maintain its mechanical integrity, especially in polluted environments.
It is used in combination with porcelain or toughened glass as the insulating material. Zinc sleeve insulators are compliant with industry standards such as ANSI and BS, and are essential components in high-voltage power transmission and distribution systems, providing both insulation and corrosion protection.
