The x-ray tube assembly is designed for integration in the production of new medical radiographic and fluoroscopic stationary and mobile devices, as well as for installation in compatible devices in case of replacement of the transmitter during repair and maintenance of the majority of X-ray devices in service.
The X-ray tube assembly is equipped with an X-ray tube manufactured by “Svetlana- X-ray” JSC with focal spots of 0.6 mm and 1.2 mm at an allowable maximum voltage of 150 kV. The tube type is 27-75BD67-150. X-ray tube assembly connection is compatible with IEC 60526 high-voltage cable connectors.
