Abstract

A study on the dielectric characteristics of various polymer nanocomposite materials should be conducted to design an electrically reliable high-voltage superconducting apparatus. Especially, the dielectric characteristics of solid insulation materials are important for designing current lead parts, and solid insulation materials are indispensable for designing superconducting coil parts. In this paper, dielectric experiments on Linear Low Density Polyethylene with Natural Rubber (LLDPE-NR) with different weight percentages of Montmorillonite (MMT) nanofiller are conducted under High Voltage Alternating Current (HVAC) and Impulse voltage for various types of electrode arrangement. Different types of electrode arrangement systems are used to examine the dielectric characteristics of insulation materials according to electric field concentration. During the first stage, several samples of LLDPE-NR are made by using hot compressed moulding processes which are consists of different percentages of MMT nanofiller such 3%, 5%, and 7% with thickness of 3mm. All these sample preparations are done according to steps with specific time of heating and cooling processes in order to produce the samples with the best condition and need to retain their morphological structures and also chemical compositions. Then, those samples are tested using both HVAC and Lightning Impulse Test until breakdown process occur. Based on collected and analyzed data results from both tests, 7wt % of nanofillers is the most suitable percentage of nanofillers that will enhance the electrical insulation characteristic.
