The electrical insulating characteristics of the dehydrated zeolite filled DGEBA (diglycidyl ether of bisphenol A)/MDA (4,4''''-methylenedianiline)/SN (succinonitrile) system were studied. The dielectric breakdown strength of cured specimens was measured using needle-plane electrode geometry, and the effects of natural zeolite on the electrical insulating properties discussed. As the zeolite content increased, the dielectric breakdown strength increased, and the time until the complete puncture by the tree channels also increased due to the barrier effect of the zeolite particles. The electrical tree channel propagated along the weak point of interface between the zeolite and the epoxy resin, As the zeolite content increased, the dissipation factor and relative permittivity both increased to convergent values of 0.085 and 6.98, repectively. The average volume resistivity was 2.2×10¹⁵ Ω·cm.
