Abstract：This paper analyzes the measurement and calculation method of volume resistivity of buffer layer material in JB/T 10259—2014 standard firstly, and then combined with the actual construction of high-voltage cable and the material characteristics of water-resistant buffer layer of high-voltage cable, reveals the volume resistivity test method of buffer layer in JB/T 10259—2014 standard can not reflect the actual situation of buffer layer in high-voltage cable in terms of contact area and applied load. A large number of test data show that the volume resistivity of buffer layer material is closely related to the pressure and electrode contact area. In order to measure the volume resistivity of buffer layer material more accurately, the test method which can reflect the actual contact mode between corrugated aluminum sheath and buffer layer is necessary.
