Medical cable

plug-in type4-wire

Short Description
The 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 output by the high voltage generator to the two poles of the x-ray tube, and send the heating voltage of the filament to the filament of the x-ray tube.

Classification
The structure of high-voltage cables: according to the arrangement of the central lines, there are two types: coaxial (concentric) and non-coaxial (non-concentric).

Precautions for use

• Prevent excessive bending. Bending radius should not be less than 5-8 times the diameter of the cable to avoid cracks and reduce insulation strength.
• Always keep the cable dry and clean to avoid erosion by oil, moisture and harmful gases to prevent rubber aging.
• Cable accessories can be ordered separately.
• When the high voltage cable is used, the bending radius should not be less than 66 mm.
