Improwement on Surface Tracking and Tensile Stress of Insulator wia the used of Aluminium Oxide Filler

摘要

Mechanical effect is one of many causes that influence surface tracking activity of electrical insulation. Mechanical stress is also a main cause that deteriorates the property of cable spacer used in delivered electrical power through transmission line. This paper investigates on surface tracking and tensile stress performance of composite insulator material in order to improve insulator property. Specimen were made from epoxy resin and additive fillers tested under the condition of contamination. The filler ratio were used from 0 To 50% with incremental of 10%. The result showed that fillers have significance improvement on inhibition of the degradation on insulators when the concentration of filler is increased, the tracking time has increased until 40% of filler. Moreover, the improvement on the tensile stress is also increased. It is clearly showed that addition of filler not only improve on the time for surface tracking on insulator surface but also helps improve on mechanical stress property of insulators as well.
