The invention aims at providing a method for manufacturing a local discharge model of conductive particles on the insulating surface of an intermediate head of a cable. According to the method, a common XLPE (Cross Linked Polyethylene) cable is directly manufactured into a model in which conductive or semiconductive impurities are attached to the main insulating surface, and the problems exposed when the intermediate head of the cable is manufactured and installed can be really reflected. In order to solve the technical problems, through steps of peeling cables, binding, washing, connecting and the like, the local discharge model of the conductive particles on the insulating surface of the intermediate head of the 10kV cable can really reflect the representative typical defect property, characteristic and discharge mechanism, which are exposed during laying, installation and operation processes of a power cable line, realizes effective extraction of typical defect local discharge characteristic quantity and obtains pure local discharge signal spectrum characteristic. The method provides convenience for researchers to safely and repeatedly test, and data are more real and reliable.
