天然酯油变压器对环境友好，由可再生资源制造。其最大的特点是防护安全性大

Natural ester oil transformers environmentally friendly, manufactured from renewable resources. <br>The biggest feature is significantly improved safety protection: natural ester ignition point is 360 degrees, 160 degrees and mineral oil. Natural esters made from insulating transformer has so far not fire recording medium; can not install the sprinkler system and firewall; good heat resistance and improved overload devices extend equipment life. <br>But he is equally obvious limitations, the current application only on lower capacity transformer (100MVA and below) and voltage (132kV and below), the European individual cases can do 400kV such as dielectric performance than mineral oil, so the transformer volume will be larger, heat transfer characteristics as good as mineral oil, and therefore require more radiators or coolers, usually 3 to 4 times the price of mineral oily,

Natural ester oil transformers are environmentally friendly and are manufactured from renewable sources.<br>Its biggest feature is a significant increase in safety: natural ester burn point is 360 degrees, while mineral oil is 160 degrees. Transformers made of natural ester insulation media have so far no fire recordings; spray systems and firewalls can be installed without installation; and good heat resistance improves equipment overload capacity and extends equipment life.<br>But his limitations are also obvious, currently only in low capacity (100MVA and below) and voltage (132kV and below) transformers, there are individual cases in Europe can do 400kV, such as dielectric performance is not as good as mineral oil, so the transformer will be larger in volume, heat transfer characteristics are not as good as mineral oil, So more radiators or coolers are needed, usually at 3 to 4 times the price of mineral oil,

So far, the transformer made of natural ester insulating medium has no fire record; spray system and firewall can not be installed; good heat-resistant performance improves the overload capacity and prolongs the service life of the equipment.<br>However, its limitations are also obvious. At present, it is only used in transformers with low capacity (100mva and below) and voltage (132kV and below). In Europe, there are some cases where 400kV can be achieved, such as the dielectric property is not as good as mineral oil, so the volume of transformer will be larger, and the heat transfer property is not as good as mineral oil, so more radiators or coolers are needed, and the price is usually 3-4 of mineral oil Times,<br>
