The electric breakdown strength of polymer composites (PC) polyethylene - low-density polypropylene (PP-LDPE) with various supramolecular structures (SMS) was studied at the stable electric field in the temperature range of 293-370 K, under various conditions. It was shown that the breakdown strength (E-bs) of PC increases with increasing voltage rise rate, and decreases with increasing temperature. The existence of dependences between electrical durability (tau(E)) and intensity of constant electric field (E-bs(v(E))) indicates that the electrical destruction of PC is a kinetic process, the rate of which is determined by the electric field strength and temperature.
