Abstract

The flame-retardancy of enamelled wires was studied by using a cone calorimeter. The characteristic parameters including time to ignition, heat release rate, total smoke release and so on, were obtained. The effect of heat radiation flux on the flame retardancy was analyzed. The results show that the flame retardancy of enamelled wires is related to the content of different components in the composite insulation layer. Polyimide enamelled wires have good flame retardant performance, followed by corona resistant wire with filler, and ordinary polyamide imide composite polyester imide enamelled wire has poor flame retardant performance. In conclusion, the heat release rate measured by cone calorimeter can be used for evaluate the flame retardancy of enamelled wires and provide a reference for the development and application of flame retardant enamelled wires.
