METHOD OF MODEL CONDUCTORS' INSULATIONS' DISCONTINUOUS CROSS-LINKING

摘要

The solution can be used in electrotechnical industry in testing of cable insulation cross linking. By the proposed solution it is possible to achieve a fast heating of a sample to a required temperature, which enables an exact definition of netting time and evaluation of the test and to process of netting. The netting is performed in an atmosphere of inert gas, which eliminates negative influences of the surrounding environment on the insulation characteristics. The model wires are fixed in a pressure tank and then they are connected to a source of electric heating current, while the netting tank is filled with an inert gas. After netting the model wires are cooled to the temperature of the surrounding environment by cooling water.<IMAGE>
