Description:

Product Overview
The SCB14 series epoxy resin cast dry-type transformer is flame-retardant, explosion-proof, maintenance free, pollution-free, small in size, and can be directly installed in the load center due to its coil being encapsulated by epoxy resin. At the same time, the scientifically reasonable design and pouring process result in smaller partial discharge, low noise, and strong heat dissipation capacity of the product. It can operate for a long time under 140% rated load under forced air cooling conditions, and is equipped with an intelligent temperature controller with fault alarm, overtemperature alarm, overtemperature trip, and black box functions. It is connected to a computer through RS485 serial interface for centralized monitoring and control.

Working Conditions

Installation height: altitude not exceeding 1000m
The waveform of the power supply voltage:resembling a sine wave
Symmetry of Multiphase Power Supply Voltage: The power supply voltage connected to the multitransformer should be approximately symmetrical
Environmental temperature:maximum temperature+40°C; maximum daily average temperature+30°C; maximum annual average temperature+20°C; minimum temperature-30°C (applicable to indoor transformers)

Model Meaning

S	Three-phase transformer
C	Forming solid casting
(B)	Low voltage foil coil
	Deslgn serial number
