Product description:

Recent years, with the improvement of people's sustainabledevelopment ideas and environmental awareness; regarding electrical insulatingoil, people turning from non-renewable and difficult degraded mineralinsulating oil to better electrical properties, non-toxic and harmless,biodegradable and renewable, natural vegetable insulating oil (i.e. naturalester insulating oil); and make it as new alternative to mineral insulating oil.

From the perspective of future economic development, China is increasingdependence on petroleum resources. With the depletion of global petroleumresources, the use of vegetable insulating oil instead of mineral insulatingoil can alleviate the shortage of petroleum resources. Therefore, research on vegetableinsulating oil transformer has many aspects of comprehensive economic value andfar-reaching social benefits.

The natural ester insulating oil transformer is eco-friendly, and evenif it leaks, it will not pollute surrounding environment; the transformeradopts special technology and materials to ensure its non-flammable andnon-explosive, and has the same safety level as the dry-type transformer.

Main advantages:

①Renewable, degradable, green andenvironmentally friendly;

②High ignition point, excellent firesafety performance;

③Perfect dielectric properties;

④Strong water absorption, hydrolysisprotection, which significantly extend the life of the transformer;

⑤Higher heat resistance level, thetransformer with natural ester insulating oil perform better high temperatureand overload capacity.

Key technologies:

① Using natural ester insulating oil asthe insulating medium of the transformer;

②Applying vacuum oil injection, nitrogenfilling and other process technologies, to ensure the moisture and gas contentin the transformer oil are within spec limits;

③Use special welding structure, nitrogensealing and other techniques to avoid contact between insulating oil againstair, and delay oxidation and aging speed of natural ester insulating oil;

④Use special oil tunnel design structureto reduce the transformer temperature rise;

⑤Develop high-temperature solidinsulation materials to cooperate with natural ester insulation oil, to developtransformers with higher temperature rise limits.
