Features of Products
This series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy. Therefore the resin insulating dry-type transformer is flame-retardant. explosion-proof, free from maintenance and pollution and it is compacted and can be installed at load center. Besides, with scientific and reasonable design and coating craftwork, it has advantages of low partial discharge capacity, low noise and good heat dispersion. It can run over a long time with 140% rated load in the circumstance of cold wind. It applies intelligent temperature controller to conduct centralized monitoring and control.Dimensions:
