Abstract: A flexible cable for conducting a high-voltage from a high-voltage source to a machine or item of equipment requiring high-voltage operation, such as an x-ray source for medical or industrial applications, an ion accelerator, or similar item of medical, industrial, or scientific equipment. The cable includes a cable core which has at least one core conductor, at least one internal insulating layer surrounding the cable core, the internal insulating layer comprising a cross-linked very-low-density polyethylene material, a conductive shield surrounding the internal insulating layer, and an outer insulating jacket. The very-low-density polyethylene material includes a silane material for facilitating the cross-linking. The very-low-density polyethylene material can have a dielectric constant that is less than 3, and preferably less than about 2.3.

The cable includes a cable core which comprises at least one core conductor, at least one internal insulating layer surrounding the cable core, the internal insulating layer comprising a cross-linked very-low-density polyethylene material, a conductive shield surrounding the internal insulating layer, and an outer insulating jacket. According to one embodiment, the very-low-density polyethylene material also includes a silane material for facilitating the cross-linking. According to another aspect, the very-low-density polyethylene material can have a dielectric constant that is less than 3, and preferably less than about 2.3.
