Abstract
A new parameter, pressure, has been introduced into study of the elect rical properties of polymers, in particular into the thermal breakdown theory for modelling of the breakdown field F(b) variations of high-d ensity polyethylene versus pressure. Theoretical F(b) values, determin ed by numerical calculation of the fundamental heat balance equation a nd the analytical expression of the conductivity, are compared with ex perimental results obtained in the pressure range 50-500 bar. Good agr eement was observed in this comparison.
