Overview
CHANGLONG DG-1 conductive paste is an electrical contact conductive paste, also known as power composite grease. It is widely used in substations and power distribution stations at the contact surfaces of busbars and busbars, busbars and equipment terminals and the contact surfaces of isolating switch contacts. It is suitable for conductive connections of the same and different metal materials. It can significantly reduce contact resistance and temperature rise, improve conductivity, reduce power loss, avoid contact surface corrosion, and improve safety performance. The product has good electrical contact conductivity and high temperature resistance, moisture resistance, oxidation resistance, mold resistance and chemical corrosion resistance performance, with no drip, no hardening, no combustion, no stimulation, long service life and other characteristics, can be used in the Temperature range below 170 ℃.

Principle
Conductive paste is applied to the contact surface of the conductive body to fill the microscopic uneven surface, reducing the contact resistance, thereby reducing the temperature rise and power loss. It can also form a protective layer, avoid oxidation and chemical corrosion, and improve the Stability and safety of the connection.
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

Steps
1. Clean the contact surface of the conductive body
2. Apply conductive paste evenly to the contact surface
3. Connect the conductive body and fasten it
4. Check the connection to ensure that there are no omissions
Notice
• Only suitable for environments below 170 ° C
• Make sure the contact surface is clean and drying before applying
Avoid use in high temperature or flammable environments
• Check Connection Stability After Use
Store in a cool drying place
