Abstract

In this paper measuring and establishing electrical and mechanical properties of foam epoxy resin Foam 128 as a material for stator winding bracing in large rotary machines are described. The material is considered in the light of partial discharges, loss factor, flexural strength and strength in compression. The aim of this paper is to decide whether the foam epoxy resin could be used when repairing damaged winding bracing in large rotary machines.
