Abstract
A cable includes an inner conductor, an inner dielectric, and a guard conductor, where the inner dielectric is between the inner conductor and the guard conductor. The cable also includes an outer dielectric, and a shield conductor, where the outer dielectric is between the guard conductor and the shield conductor. The cable further includes an additional layer of material between the outer dielectric and the shield conductor of suitable composition for reducing triboelectric current generation between the outer dielectric and the shield conductor to less than that which would occur were the outer dielectric and the shield conductor to directly adjoin each other.
