Abstract

Представлены результаты теоретических и экспериментальных исследований по определению электрофизических свойств полимерных композиций на основе поливинилхлорида (ПВХ). Изучены влияния ингредиентов на технологические свойства ПВХ композиций. Определены основные отличия электрофизичечких свойств материалов изоляции в зависимости от водопоглощения.Polyvinyl chloride (PVC) is one of the most famous and important practical tonnage polymer products. On its basis, receive semi-soft and soft (plasticized) polymer compositions used in the manufacture of cables and wires. The main problem of PVC is its very low stability. The aim of this work was to study the electrical properties of PVC insulation compositions for low-voltage power cables. The results of theoretical and experimental researches are represented on determination of electrophysics properties of polymeric compositions on the basis of PVC. Influences of ingredients are studied on technological properties of PVC compositions. The basic differences of electrophysics properties of materials of isolation are certain depending on moisture absorption. Compositions developed for the isolation of the low voltage power cables have high technological, physical, mechanical, and electrical characteristics.
