Patent ID: 7617877

Claim:
A method for making a downhole electrical transmission system, comprising: providing an electrically conductive assembly disposed within a first downhole tool string component, the electrically conductive assembly comprising a first end and being anchored to the first tool string component at a first predetermined distance from a primary shoulder of the first end of the component; stretching the electrically conductive assembly lengthwise by pulling on a second end of the assembly with a stretching tool such that the second end of the electrically conductive assembly is held; enlarging the diameter of the second end of the electrically conductive assembly to a diameter larger than an original diameter of the electrically conductive assembly by flaring the second end of the electrically conductive assembly with a flaring tool; and anchoring the second end of the electrically conductive assembly to the first tool string component at a second predetermined distance from a primary shoulder of the second end of the component.
