Abstract

In this paper, the electrical properties due to epoxy resin used in transformer of rail road signal are studied. The specimen of epoxy resin was hardened as each 3[h], 4[h], 5[h] in this experiment. In order to measure the conductivity properties, the highmegohm meter is used at temperature 25 to 140[$^{\circ}C$] and applying voltage 100 to 1000[V]. As a result of this experiment, we confirmed that 3[h] specimen is better than the others.
