Bolted

Here at Northern Power we have many different types of bolted substation categories. Some of those categories include, bolted bus supports, couplings, expansion joints, parallel connectors, stud connectors, tee connectors, and terminals. These accessories, including the bolts and nuts, are made from high-strength aluminum alloys and other materials. They are then coated with a lubricant for additional resistance to corrosion. The reduced friction provided by the lubrication coating gives a higher bolting pressure for a given tightening torque. Experience has shown that bolted joints on electrical bus conductors made with unbrushed electrical fittings, with the proper joint preparation and adequate sealing of the connection, are entirely satisfactory for aluminum-to-aluminum and aluminum-to copper connections. let us know here at Northern Power if there is anything we can do to help and answer any questions that you may have.
