description
feature
parameter
epoxy resin casting dry-type power transformer is casted by advanced process, with high reliability and long service life. protective enclosure can be added according to different protection grades. applicable to high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants and other important or special environmental places. high-performance cold-rolled oriented silicon steel sheet is adopted for the core, and the automatic manipulator laminating machine has small shearing burr and lamination coefficient, which effectively reduces the no-load loss, no-load current and noise of the transformer. no-load loss is 5% - 10% lower than manual lamination.
technical features:
low loss: comply with the energy efficiency requirements in gb20052-2020 limit values and energy efficiency grades for power transformers;
low noise: meet the requirements of low noise standard of state grid south grid;
low partial discharge: the product only has very low partial discharge, which can be controlled below 5pc.
high mechanical strength; epoxy pouring body has dense solidification structure and can bear sudden short circuit electrodynamic force without damage.
