Insulation failures linked to poor thermal stability and less tensile strength have drawn in power
transformers, power cables, aerospace industries and electrical and electronic circuits. The concerns have
developed regarding the thermal stability, mechanical breakdown strength and the safety of polyimide
insulations(PI) in electrical high voltage engineering. Several polyimide composites are selected for
evaluation in the laboratory tests. The selected composites of polyimides are made in the laboratory through a
roll ball milling process. Thermos-gravimetric analysis(TGA) and Tensile strength tests is performed by
using a universal testing machine (UTM) in accordance with American society for testing and materials
(ASTM D412). In this study these tests are performed in the high voltage laboratory at NUST University in
Islamabad.
