| description | Demand of softwood fiber has rapidly increased as a result from the variety of new softwood products. Therefore, nonwood
fibers have been introduced as alternatives in pulp for presspaper making to supplement the limited wood fiber
resources. Malaysia is the second largest producer of oil palm where the empty fruit bunch (EFB) has a potential to be
developed as an insulating paper. This paper aims to determine the performance of EFB as non-wood fiber to evaluate
its use as potential presspaper insulation in power transformer. The sample of EFB paper was produced through kraft
pulping and laboratory handsheet process. The performance of EFB and kraft paper was evaluated by impulse
breakdown test. The study is focused on the performance of insulating paper that were aged with the transformer oil at
90 °C for 30 days. In order to investigate the impulse breakdown voltage of the insulating paper, multistage impulse
generator was used. As the aging temperature increases, the breakdown voltage will decrease. The thickness of insulating
paper also has an effect to the breakdown strength as the thicker the insulating paper, the higher the breakdown voltage
will be. For no aging sample, kraft fibres dominate the breakdown strength at 28.11 kV/mm, while for sample aged at 90
°C, EFB fibres dominate the breakdown strength at 3.62 kV/mm higher than the average of kraft fibres due to an effect
of fibres arrangement between fibre-to-fibre bonding after the aging. |
