The use of 75KV or 90KV’s high voltage cables depends on what type of X ray machine the high voltage cables is used.
X-ray machine using high voltage cables is different from ordinary high voltage cables, there are generally 75KV and 90KV two models, 75KV high voltage cables for 125KV tube, 90KV high voltage cables for 150KV tube.
500mA fixed X-ray machine is suitable for 150KV spherical tube, so 90KV high voltage cables can be used for 500mA medical diagnostic camera. Generally 90KV high voltage cables can be used for all kinds of fixed X-ray machine, customers with unclear data can judge according to your type of X-ray machine.
Generally, the length of high voltage cables will not have any impact on the current, customers can freely choose the length of customized high voltage cables according to their own needs.
