The main function of the aluminum busbar expansion joint is to compensate the displacement change caused by thermal expansion and cold contraction of the busbar, so as to avoid the damage of the equipment and its joints due to hard force.
The design and application of the aluminum busbar expansion joint aims to solve the problem of thermal expansion and cold contraction caused by temperature change in the process of conduction of the busbar. The expansion joint can be expanded according to the needs, so as to adapt to the change of the displacement of the bus, to ensure the stable operation of the power equipment. In addition, They also balance the blind plate force caused by SF6 gas filling, and generate equal or similar to the blind plate force through their structure, reducing the force on the GIS (GasInsulated Switchgear) fixed bracket, thereby protecting the equipment from unnecessary stress damage.
The use of aluminum busbar expansion joint not only improves the safety and reliability of the power system, but also prolongs the service life of the equipment. They are usually braided with bare copper wire or tinned copper wire and made by cold pressing, this material and manufacturing process ensures the durability and electrical conductivity of the expansion joints. In addition, the design of the expansion joint also takes into account the compatibility of busbars and equipment joints of different materials, such as copper-aluminum expansion joints and aluminum-aluminum expansion joints, to meet the needs of various practical applications. In general, the aluminum busbar expansion joint through its unique design and material selection, effectively solve the problem of displacement and stress in the operation of the busbar, for the stable operation of the power system provides an important guarantee
