FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the primary composition of the CONTACTAL HPG paste for conductivity and protection?

A: It is primarily composed of mineral fats and various fillers including zinc particles with selected geometry.

Wiring & Installation:

Q: Which specific applications require the use of only CONTACTAL HPG, N190, or N250 pastes?

A: Contacts on busbars and braids used for feeding ovens and electrolysis trays require these specific types.

Troubleshooting & Compatibility:

Q: Is CONTACTAL HPG suitable for connections between aluminum and copper conductors?

A: Yes, it can be used on aluminum/copper contacts, but a bi-metal plate is recommended for outdoor use.

Replacement & Upgrades:

Q: Are there any other CONTACTAL pastes recommended for applications involving immersion in an insulating material?

A: CONTACTAL N190 grease is recommended for preparing aluminum contacts immersed in an insulating material.
