RADICAL-CHAIN MECHANISM OF DESTRUCTION OF POLYMERIC ELECTRICAL INSULATING MATERIALS BY PARTIAL DISCHARGES
Keywords:

The article is devoted to the development of a method of non-destructive testing of the insulating material of cable systems. The destruction of a polymer material caused by a radical chain mechanism of destruction is considered. The mechanism of destruction of polyethylene caused by electron and ion bombardment under the action of partial discharges (PD) is given. The formation of cross-links associated with the activation of double bonds during the transfer of electronic excitation energy from a polyethylene chain is shown.
