Beschreibung
Zusammenfassung:	electrical engineering, more specifically cable technology, and manufacture of insulation in various grades of cables. SUBSTANCE: electroinsulating composition comprises, wt parts: ethylene-propylene-diene rubber, 100; polypropylene or propylene-ethylene block copolymer, 10- 100: peroxide, 0.2-4; destructed polypropylene having melt fluidity index of 100-3000 g/10 min measured at 230 C and load of 2.16 kg, 3-10; propionic acid, 3,3'- thiobis-dioctadecyl ester of benzopropionic acid, 0.2- 0.4; 3,5-bis (1,1-dimethylethyl(4-hydroxy-[3-3,5-bis(4- hydroxy-2-3,5-bis[1,1-dimethylethyl-4-hydroxy-phenyl 1- oxopropyl] hydrazide,0.2-0.4; dimethylethyl)-4- hydroxyphenyl)-1-oxopropoxy] methyl-1,3-propane-diyl ester, 0.07-0.15; and tri-(2,4-di- tertbutylphenol)phosphite, 0.15-0.3. EFFECT: improved properties of the composition for insulation of wires and cables, effective protection thereof from thermal oxidation and effect of copper and improved quality of final products.
