What role does contact paste play in overhead line connector installation?

2025-08-13

Contact paste is a vital component in the installation of many aluminum overhead line connectors, particularly those that use a compression method. Aluminum naturally forms an oxide layer when exposed to air, which is a poor conductor of electricity and can lead to increased resistance and heating.

  • Disruption of Oxide Layer: The contact paste, which is often a gritty, conductive compound, helps to break through this non-conductive oxide layer during crimping.

  • Corrosion Protection: It seals the connection from moisture and air, preventing further oxidation and corrosion.

  • Improved Conductivity: By creating a more efficient electrical path, it minimizes resistance and heat generation, ensuring a stable and reliable connection for the life of the line.

Our connectors are often pre-filled with high-quality contact paste to streamline the installation process and guarantee an optimal connection.
