Overview
CHANGLONG DG-1 conductive paste full name electrical contact conductive paste, also known as power composite grease. It is widely used in substations, power distribution stations, busbars and busbars, busbars and equipment terminal connections at the contact surface and isolation switch contacts, the same and different metal conductive body (copper and copper, copper and aluminum, aluminum and aluminum) connection can be used instead of and better than the fastening connection contact surface tin lining, silver plating process, can greatly reduce the contact resistance (can be reduced by 35~ 95%), so as to reduce the temperature rise (can be reduced by 35~ 85%), improve the conductivity of the bus connection and the switch contact, reduce a lot of power loss, but also avoid various corrosion of the contact surface, especially significantly improve the safety performance of the conductive paste at the use of The safe operation of the power station provides a reliable guarantee.
DG-1 conductive paste not only has good electrical contact conductivity and high temperature resistance, moisture resistance, oxidation resistance, anti-mildew and anti-chemical corrosion performance, but also has the characteristics of no drip, no hardening, no combustion, no stimulation, long service life, even in the air heating and humidity and containing chemical corrosion gases in the harsh environment of substations and distribution (such as chemical plants, steel plants and other substations), also has a good effect. It is a national designated promotion product.
