Electrical insulation performance: oil-immersed transformer running internal high voltage, paper covered copper wire insulation can provide reliable electrical insulation, will be different potential of the winding conductors isolated from each other, to prevent the occurrence of short circuit and discharge phenomenon. Insulation paper has high electrical strength, can withstand the transformer voltage, and in long-term operation to maintain stable insulation properties, to ensure the safe and reliable operation of the transformer.
Paper covered copper wires work with the insulating oil inside the transformer to form a good insulation system. After the insulating paper absorbs the insulating oil, its insulating properties are further improved, while the insulating oil can fill the gaps in the insulating paper, enhance the overall insulation effect, and also help dissipate heat. Both work together to effectively improve the insulation reliability and heat dissipation performance of the transformer.
