A comparative study of dielectric, mechanical and structural properties of fire-protective insulation based on XLPE

Popis výsledku v původním jazyce

Paper deals with comparing of dielectric, mechanical and structural properties of primary cable insulation based on cross-linked low density polyethylene (XLPE) with different level of cross-linking. Testing material was divided into four groups according to time of exposition to low pressure steam, which initiates cross-linking reaction. The measurement of the degree of cross-linking by chemical extraction in xylene solution at 140 °C according to ASTM D2795 ? 11 followed. Dielectric properties (polarization index, volume resistivity) of the individual samples were then measured according to standards. Dielectric properties were compared with results of tensile strength test at various temperatures (50 °C, 55 °C, 60 °C) measured by dynamic mechanicalanalysis. The degree of cross-linking represented by the gel content positively influences the tensile strength, the volume resistivity and the change of structural behaviour of the material by differential scanning calorimetry was also o
