The effect of calcium carbonate and calcined clay micro filler materials on the electrical characteristics of polyvinyl chloride for cable insulation
Polyvinyl Chloride (PVC) is widely used as cable insulation for low voltage application. In order to strengthen the electrical properties of the material, some additives have to be added. In this project, various fillers were compounded with PVC. The main parameters that have been studied were diele...

Polyvinyl Chloride (PVC) is widely used as cable insulation for low voltage application. In order to strengthen the electrical properties of the material, some additives have to be added. In this project, various fillers were compounded with PVC. The main parameters that have been studied were dielectric strength, and the dispersion of PVC molecules. The polymer structure of PVC was altered after undergo high voltage stress and it can be related to the breakdown voltage value. The type of fillers that were used in this experiment is Calcium Carbonate NCC-P 1T, Neolite SP, and Calcined Clay. Firstly the density of each test objects was measured using density meter and the value obtained must within the SIRIM specification. Then the dielectric strength test was done under AC stress to observe the breakdown properties. It is observed from the tests that when the density or Specific Gravity (SG) of test sample increased, the breakdown voltage also increased.
