ABSTRACT:
A non-fragmenting surge arrester core comprising a conductive core comprising a series array of non-linear resistor elements stacked in face-to-face contact between the inner end faces of a pair of terminal end pieces encased within a plastic impregnated jacket of bi-directional weave fabric woven of high tensile strength strands of which the strands of one of the bi-directional orientations have a greater tensile strength than the strands of the other bi-directional orientation with the greater strength fabric strands aligned lengthwise of the jacket. A tensioned constrictive hoop of high tensile strength material compressively circumscribes a portion of the jacket weave fabric overlying a peripheral area of the terminal end pieces between its two end faces, which peripheral area preferably conforms to a curvelinear depression groove circumscribing the terminal end pieces.
