Heating and Cooling Impact on Mechanical Properties of RIP Electric Insulator for High Voltage Inputs

Abstract:

The mechanical properties investigation results obtained by tension and indentation tests of RIP (resin impregnated paper) electric insulator are presented. Tension and indentation tests of the RIP electric insulation material in wide temperature range are conducted. The common relations between strength and temperature as well as between hardness and temperature for the RIP electric insulation are established. The ratio of ultimate tensile strength to Brinell hardness is performed to be constant (about 1/3) irrespective of temperature, that means a possibility of the RIP electric insulation mechanical properties evaluation by the instrumented indentation test.
