ABSTRACT:
A polymer jacket tube includes a conductor bar which has a conductor insertion hole at its lower end, a rigid insulation sleeve around the outer periphery of the conductor bar, and a polymer covering on the outer periphery of the insulation sleeve. The insulation sleeve includes a large-diameter insulation sleeve at the lower, outer peripheral portion of the conductor bar, and a small-diameter insulation sleeve surrounding the outer peripheral portion of the conductor bar except for the distal end thereof. An embedded metal fitting for electrical stress relief is buried in the continuous portion of the large-diameter insulation sleeve and the small-diameter insulation sleeve. A cone-shaped reception port receives the stress cone of a cable terminal and is located at the lower end of the large-diameter insulation sleeve, which reception port is in communication with the conductor insertion hole of the conductor.
