In X-ray machine, x ray high voltage connector high-voltage generator and spherical tube. The main function of x-ray machine with high voltage cable is to transmit high-voltage output of high-voltage generator to spherical tube and heat the filament of spherical tube.
The conductive core wire of x-ray machine with high voltage cable has two cores and three cores. The core wire is composed of multiple copper wires. The outer part is covered with insulation skin, and there is insulation skin between the cores.
A capacitance distributed along the length of the cable is formed between the x-ray machine with high voltage cable core and the metal shield layer. The capacitance is small, but the electric energy on the capacitance can not be ignored because of the high voltage. Therefore, special attention should be paid to maintenance. After pulling out the cable, discharge the core line to the ground, so as to avoid electric shock.
