Abstract: This paper discussed the principle of the hot-wire measuring method in detail and four insulating materials were measured in the different temperature by the efficient measuring method.Origin7.0 which is powerful software for data analysis and graph plotting,was utilized during the data processing. The proposed method are of practical value, and can be applied to measure the thermal conductivity of various insulating materials.

Keywords: Insulating materials; Thermal conductivity; Hot-wire technique; Origin7.0
