Installation of closed tube bus is the industrial, construction and other industries are widely used electric products, its current conveyor is bigger, so the resistance of the power supply and distribution system as long as there is little change, will produce larger heat, how to reduce the installation of closed tube bus tolerance , to assure the safety of power supply and distribution system tube bus will be very important.
1. During the installation process, it is recommended that the conductive aluminum busbar at the insertion interface be replaced by double-sided insertion, which can increase the contact area at the insertion interface by one time, reduce the contact resistance by one time, and avoid overheating and oxidation of conductive aluminum busbar here.
2. the joint connection between the closed tube bus, some are used in the conductive aluminum/copper bar drilling bolt connection.This will reduce the cross section, resulting in the heating and oxidation of the electro aluminum/copper busbar around the borehole.It is suggested that aluminum/copper platen should be used at the junction of the bus bar, which is wider than the section of the conductive platen, and bolts should be used on both sides of the aluminum/copper platen to ensure the contact surface between the aluminum/copper platen and the conductive aluminum/copper platen is close and balanced to meet the technical requirements.
3. Whether the connection between closed tube bus units is reliable is directly related to the safe operation of the whole power supply and distribution system.
