SCB14 Epoxy resin cast dry-type transformer

Scb14 series epoxy resin cast dry-type transformer, because its coil is encapsulated by epoxy resin, is flame-retardant, fire-proof, explosion-proof, maintenance free, pollution-free and small, and can be directly installed in the load center. At the same time, the scientific and reasonable design and pouring process make the product have less partial discharge, low noise and strong heat dissipation capacity. Under the condition of forced air cooling, it can operate for a long time under 140% rated load. It is equipped with intelligent temperature controller, which has the functions of fault alarm, overtemperature alarm, overtemperature trip and black gate. It is connected with the computer through RS485 serial interface, which can be monitored and controlled centrally.
