6. Nationally designated promotional products
Principle
Conductive paste is applied to the contact surface of the conductive body to fill the microscopic unevenness to form a stable conductive layer, thereby reducing the contact resistance and temperature rise. It also isolates air and corrosion media, avoids oxidation and chemical corrosion, and ensures the Stability and Reliability of electrical contact.
Applications
The connection between the bus and the bus in the substation and the distribution station, the connection between the bus and the equipment terminal, the contact surface of the isolating switch, the connectors and switch contact points of household appliances such as televisions
Standards
Cone penetration 200~ 315 1/10mm, ph value 6~ 8, cold contact resistance change X ≤ 0.95 before and after paste, moisture resistance K ≤ 1.3, alternating heat and humidity temperature cycle performance K ≤ 1.5, temperature rise ≤ 65K at rated current, drop point ≥ 200 ℃, evaporation loss ≤ 1.5%, contact resistance stability coefficient K ≤ 1.5, low temperature performance No checking, volume resistivity ≥ 108Ω cm, salt fog corrosion performance K ≤ 1.5 and metal conductor contact surface No corrosion
Steps
1. Clean the contact surface of the conductive body to ensure no dirt and oxidation layer
2. Apply conductive paste evenly on the contact surface
3. Connect the conductive body and tighten it to ensure good contact
4. Check the connection to confirm that there are no voids and excess paste
Notice
• Only suitable for environments below 200 ° C
• The contact surface must be cleaned before application to avoid impurities affecting the performance
• Apply evenly to avoid being too thick or too thin
Store in a dry, cool place away from heat and direct sunlight
• Timely sealing of the container after use to prevent contamination or drying of the paste
