The busbar expansion joint is the key component connecting the busbar and belongs to a kind of power station hardware, which is widely used in power, chemical, smelting and other industries. With excellent expansion performance, it can effectively compensate the deformation and vibration deformation of the bus caused by temperature change, prevent the equipment from being damaged, and prolong the service life of the equipment.
The temperature range of the bus expansion joint mainly depends on the actual demand of the customer, the product use environment and the working demand, and different materials can be selected for manufacturing according to the actual situation. Generally, when the material of connecting pipe and liner barrel is carbon steel, the operating temperature range of expansion joint is generally - 20 ℃~420 ℃; When the material is stainless steel (same as bellows), the temperature range is - 196 ℃ - 700 ℃.
The copper busbar expansion joint can compensate the cold expansion of the bus when it is heated, play a role in adjustment, prevent the equipment joint from being stressed, ensure the normal operation of the equipment, and improve the stability and reliability of the equipment.
