Does the length of the high voltage cable affect the final imaging effect?
When many customers inquire about high-voltage cable products, they will ask whether the length of the high-voltage cable affects the final imaging effect, and how to judge whether it does. First of all, let us first understand the high-voltage cable.
What is a high voltage cable? In the high-voltage generating device of large and medium-sized X-ray machines, the high-voltage transformer and the X-ray tube assembly are assembled separately, and the two are connected together by two special cables. This special wire is called a high-voltage cable. , is an anti-shock safety cable.
The function of the high-voltage cable is to transmit the pulsating DC high voltage generated by the high-voltage generator to both ends of the line tube, and at the same time transmit the filament heating voltage generated by the high-voltage generator to the cathode filament of the X-ray tube to form a high-voltage circuit.
Types of high voltage cables:
1. Classified according to cable withstand voltage: divided into X-ray generators with pulsation-resistant DC 100kVp, 150kVp, and 200kVp center point grounding.
2. Classified according to the number of core wires in the cable: it can be divided into two core wires, which are used for X-ray tubes with single focus and one filament;
Three core wires are used for X-ray tubes with large and small two-focus filaments; four core wires are used for dual-focus X-ray tubes with grid control or triple focus.
3. Classification according to the distribution position of the inner core wire of the cable: it can be divided into two forms, namely coaxial high voltage cable and non-coaxial high voltage cable
Requirements for high-voltage cables: it must have a certain cross-sectional area to achieve high-voltage resistance to transmit high voltage; it must also reduce the cross-sectional area as much as possible to make it light and soft to meet the needs of frequent movement of the X-ray tube head and cable bending .
Different X-ray machines need to choose high-voltage cables with matching lengths according to the size of their own X-ray tubes.
