Introduction
The full name of Changlong DG-1 conductive paste is electric contact conductive paste, also known as electric compound grease. It is widely used in substations and power distribution stations, on the contact surface between the busbar and the busbar, between the busbar and the equipment terminal, and the contact surface of the isolating switch contact. Conductors of the same and different metal materials (copper and copper, copper Used for connection with aluminum, aluminum and aluminum), which replaces and is superior to the process of tinning and silver plating on the contact surface of the fastened connection, and can greatly reduce the contact resistance (can be reduced by 35-95%), thereby reducing the temperature rise ( It can be reduced by 35-85%), improve the conductivity of the busbar connection and the switch contact, reduce a large amount of power loss, and avoid various corrosions on the contact surface, especially greatly improving the safety performance of the place where the conductive paste is used. It provides a reliable guarantee for the safe operation of substations and distribution stations.
DG-1 conductive paste not only has good electrical contact conductivity, high temperature resistance, moisture resistance, oxidation resistance, mold resistance and chemical corrosion resistance, but also has no dripping, no hardening, no burning, no stimulation, long service life, etc. Even in substations and power distribution stations with humid and hot air and harsh environments containing chemical corrosive gases (such as chemical plants, steel plants and other substations and distribution stations), it also has a good effect. It is a product designated by the country to promote.
DG-1 type conductive paste can be used in the temperature range below 170°C, and DG-2 type conductive paste can be used in the temperature range below 200°C.
Applications
DG-1 conductive paste is widely used in substations and power distribution stations on the contact surfaces between busbars and busbars, between busbars and equipment terminals, and on contact surfaces of isolating switch contacts. Conductors of the same and different metal materials (copper) Used for connections with copper, copper and aluminum, aluminum and aluminum), and can also be applied to connectors and switch contact parts of household appliances such as televisions. After coated with conductive paste, it can reduce Voltage drop and arc, avoid oxidation and corrosion of exposed wires, improve reliability of household appliances and prolong service life.
