SC(B) Epoxy resin casting dry type transformer

Product Introduction

As the coils of resin insulated dry type transformer are encapsulated by the epoxy resin, they are nonflammable, fireproof, explosion­proof, maintenance-free, no pollution, small volume, and can be installed in the load center directly. Meanwhile, the scientific and reasonable design and casting technology enable the products to have lower discharge capacity, low noise and strong heat dissipation, they are able to run for a long time under 140% rated load under forced air cooling condition. Besides, the dry type transformer are equipped with intelligent temperature controllers, have functions of trouble alarm, over temperature alarm, over-temperature tripping and black box, can be connected with the computer through RS485 serial interface to realize centralized monitoring and control.
