Abstract: A conductor device 100, preferably being configured for low temperature applications, comprises multiple conductor wires 10 being arranged along a longitudinal extension of the conductor device 100, and an electrically insulating encapsulation material 20, wherein the conductor wires 10 are encapsulated in the encapsulation material 20, so that each conductor wire 10 is covered by the encapsulation material 20 in all radial directions relative to the longitudinal extension of the conductor device 100, wherein the conductor wires 10 have electric superconductivity at an operation temperature equal to or below ?196° C., and each conductor wire 10 has two longitudinal end sections 11 and a self-supporting wire section 12 therebetween. Furthermore, an electrical conductor arrangement including the conductor device and a method of manufacturing the conductor device 100 are described.
