The semiconductor layer of the X-ray high-voltage cable is tightly wrapped on the insulating layer with a semiconductor rubber, which is gray-black. The role of the semiconductor layer of the X-ray high-voltage cable is to eliminate the electrostatic field between the outer surface of the insulating layer and the metal shield.
It can be known from physics that when a dielectric (insulator) is subjected to an external electric field, its molecules will be polarized to form an electric dipole, and arranged in the direction of the external electric field, so that an equal amount of Positive and negative charges. These charges are strongly bound by the nucleus and cannot leave the dielectric, called bound charges. Since the core wire of the X-ray high-voltage cable works under a DC high voltage, a high-voltage electrostatic field is formed, the insulating layer is polarized, and a negative charge will appear on the inner surface layer close to the core wire, and a positive charge will appear on the outer surface layer. When the metal shielding layer and the insulating layer have poor contact somewhere, the positive charge at the poor contact will form a high-voltage electrostatic field with the metal shielding layer, ionizing the gas between the two and destroying its insulating performance. Therefore, a semiconductor layer is added between the two layers. Due to the electron movement in the layer of the semiconductor layer of the X-ray high-voltage cable, the high-voltage electrostatic field cannot be formed at the poor contact.
