Equipamento para ensaios de trilhamento e erosão em isolamentos poliméricos.

Abstract

This work proposes to present the methodology of a project for the construction of an equipment able to check the resistance of polymeric insulation to tracking and erosion, as proposed in the standard IEC 60587 (2007), which proposes tests on an inclined plane. Due to the high value of the test equipment, it is necessary to develop an effective and low-cost equipment for the measurement of tracking and erosion resistance. The development of the new mechanism aims to study some electric insulating materials under severe environmental conditions. The equipment will be used in the evaluation of new polymeric materials and coatings to be applied on insulators in order to mitigate the leakage current and increase your electrical supportability. In order to contribute to the sedimentation of knowledge on implementation of tracking and erosion tests in polymeric materials, some trials were carried out. The studies used samples based on silicone rubber with loads of alumina trihydrate and nanosílica at different concentrations. After the tests, based on the results, there were some statistical analysis. Finally, it was found that the use of these loads increased the resistance of the samples to the tracking and erosion.
