The diagram and the device of ceramic-metal high-voltage vacuum arc-suppressing chamber (KDV) is described. The technological chain of assembly of KDV conductive node is provided. The technology of exhaust-tube group pumping, soldering, annealing is described. Manufacturing technique features of arcsuppressing cameras on 110 kV are shown. The aim of the work is increase in production capacities of enterprise and implementation new largesize cameras into production. The question to increase the resource of vacuum arc-suppressing cameras to 105 switches by increasing plasma stability in vacuum arc chamber and the complex of other constructive and technology solutions is considered. The main means for increase the output is the transition of production from nowadays accepted option of exhaust-tube pumping of cameras to exhaust-tubeless technology of receiving vacuum. In the course of pumping there is deleting of all gases both free and dissolved in product details from the volume of product. These purposes require long warming up of a jacket and details of products at the temperature up to 5000C. 

Key words: vacuum, technologies, arc extinguish chamber, ceramic-metal, arc, electrodes, outgassing, nodes, pumping, temperature, sealing, a jacket, soldering, solder.
