The Effect of Electric Gas Discharge Radiation Cross-Linking Technology on the Mechanical Strength of Polyethylene Cable Insulation

NOVIKOV Gennadii K. (Irkutsk National Research Technical University, Irkutsk, Russia) Associate Professor, Cand. Sci. (Eng.)

The article analyzes the results from comparative investigations of electrical insulation for medium-voltage cables with low-density cross-linked polyethylene (XLPE) insulation made using the technology of cross linking by means of X-ray radiation from electrical gas discharge (EGD). The experimental data obtained on samples made in the form of rupture blades cut from polyethylene plates and films in accordance with GOST IEC 60811-2-1, as well as on full-scale cable samples, are considered. The penetration depth of X-ray radiation from EGD into low-density cable polyethylene is estimated. Comparative investigations of changes occurring in the electrophysical properties and mechanical strength of low-density cable polyethylene caused by the X-ray radiation from EGD and due to the effect of electron beam have been carried out.

Key words: cable insulation, low-density polyethylene, X-ray radiation, absorption depth, electric gas discharge, electrical conductivity, mechanical strength, radiation-aided cross-linking
