High voltage cable for digital x ray machine - Newheek X ray Cable

High voltage cable for digital x ray machine

High voltage cable connects the high voltage generator and the x-ray tube head in large and medium-sized x-ray machines.
The high voltage cable is one of the essential parts on the X-ray machine.
High voltage cable connects the high voltage generator and the x-ray tube head in large and medium-sized x-ray machines.
The function is to send the high voltage outputted by the high voltage generator to the two poles of the x-ray tube, and send the filament heating voltage to the filament of the x-ray tube. High voltage cable structure: There are two types of coaxial (concentric) and non-coaxial (non-concentric).
(1) Conductive core
The innermost layer of the high voltage cable. Each heart line consists of multiple strands of thin copper wire, which is wrapped with insulation. Insulation requirements: withstand 50Hz, 1000V AC test for 5min without breakdown. The two hearts are exclusively for single-focus x-ray tubes, and the three hearts are for dual-focus x-ray tubes. (Insulation between each heart line)
(2) High voltage insulation layer
Outside the heart line, it is the main insulation layer of high-voltage cable, made of rubber and chemical raw materials, and the thickness is between 4.5-13mm. It has good mechanical strength and toughness and can be bent within a certain range. The pressure resistance requirement is generally 50-200kV.
(3) Semiconductor layer
Adhered to the insulating layer, made of semiconductor material and rubber, grayish black, 1-1.5mm thick. The role is to eliminate the electrostatic field between the outer surface of the insulating layer and the metal shield.
