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.
