发明名称 Impedance heating system
摘要 An impedance heating system generally includes an outer tubular member having a first end and a second end, and an inner tubular member having a first end and a second end positioned coaxially inside the outer member. The inner member extends substantially the entire length of the outer member such that the first and second ends of the inner member terminate in close proximity to the first and second ends of the outer member, respectively. A power source is electrically connected to the first end of the inner member for supplying current to the inner member upon energization of the impedance heating system. A return path for current flow from the inner member to the power source generally includes either the outer member or a return cable electrically connected to the inner member. One or more spacer members are secured around the circumference of the inner member at spaced-apart intervals. Each spacer member includes a plurality of radially outwardly extending flanges for coaxially positioning the inner member within the outer member. The flanges are adapted to allow for the inner member and the spacer members to be slidably received within the outer member. Dielectric insulation is disposed between the inner member and each spacer member to electrically isolate the spacer members from the inner member.
