Experimental Investigation on Electrical and Mechanical Characteristics of PVC Cable Insulation with Silica Nano Filler

Abstract

Cables are an integral part of the power transmission and distribution network. As the voltage level increases, amount of insulation used in the cable increases. Therefore a need arises for a material with better insulation characteristics to be used in cables. The dielectric strength of cable insulation depends on many factors such as the existence of filler material in the insulation. In this work, laboratory studies on a new filler material for cable insulation have been conducted. The influence of Silicon dioxide (SiO2) filler on the dielectric and mechanical properties of polyvinyl chloride (PVC) cable were analyzed. Comparison is made between the result of measurement and the actual value of the pure specimen. From the results, it is shown that the filler material has improved the dielectric and mechanical properties of the cable insulation.

The effect of PVC’s resin K-value on the mechanical properties of the artificial leather

“…Comparing to pure resin, the blending has slightly lower elongation (2.26 -5.07%), probably because of difficulties in obtained homogenous plastisol when blending two resin with different molecular weight. Some paper also shows similar negatives effect of blending inhomogeneitiesto the tensile strength and elongation (Mehdipour et al, 2017;Selvaraj et al, 2015). Therefore, there is should a compromise between the defect and mechanical properties that still suited the product requirements.The table 3 and figure 2 shows that the best compromise is sample D5A5 that gives none defect with tensile strength value 3.95/1.28 N/mm 2 (vertical/horizontal) and elongation 43.61/181.89 % (vertical/horizontal).…”
