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.

A fragmentation resisting core unit adapted for installation within a surge arrester outer housing and including a conventional array of non-linear core components arranged in series along a core axis between the inner faces of a pair of end terminals with adjoining faces of the array subjected to sufficient compressive force that the compressed core array is electrically conductive. This core array under compression is circumscribed by a plurality of untensioned, high tensile strength annular bands of an insulant longitudinally circumscribing the compressed core array in mutually transverse planes with each reinforcing band extending longitudinally of the compressed electrically conductive core array in a manner to overlie the outer end face region of each end terminal in a closely adjoining relationship.
