Specification

SC12Series 35kV Class Non-Excitation Voltage Regulation Power Transformer

Dry-type transformer meets China's national first level energy efficiency standards.Resin insulated dry-type transformer, due to the coil is encapsulated by epoxy resin, so it is flame retardant, fireproof, explosion-proof, maintenance-free, non-polluting, small in size, and can be directly placed in the load center. Due to the scientific and reasonable design and casting process, the product has smaller partial discharge, low noise, strong heat dissipation ability, and can be operated for a long time under 125% of the rated load under the condition of forced air-cooling, and is equipped with a temperature controller, which has the functions of fault alarm, over-temperature alarm, over-temperature trip, and black-box function, and is connected to the computer through the RS485 serial interface to enable centralized monitoring and control.
