The simplest test is heat the the given substance (solid of any shape) on one end,after a while check the temperature on the other end. If it measures more than room temperature then the given substance is conductor of heat, then it conducts electricity also, otherwise it is electrically insulator.
Mainly heat conduction happens due to the free electron movement in substance, the electrical conduction also happens for the same reason.
Apparatus required are Bunsen burner and a thermometer.
