Product Overview

The company adopts high-quality materials and advanced process technology to professionally produce BK, SG, SGG series three-phase and single-phase dry-type isolation transformers. In the power grid, this series of transformers not only have the voltage transformation function, but also can isolate the secondary harmonics of the power grid to the equipment, and protect the machine from heat generation and the reduction of the service life of insulating materials.
It is especially suitable for imported equipment (380V in → V out, 380V in → any voltage output, 220V in → any voltage output) with specifications ranging from 1KVA to 1000KVA.
BK, SG, SGG series dry-type transformers are widely applicable to AC 50~60HZ. The input and output voltage of the product (single-phase, three-phase or multi-channel input and output, etc.), connection mode, tap position adjustment, winding capacity distribution, secondary winding configuration, outer box (selected according to different use environments) can all be carefully designed and manufactured according to user requirements.

Energy-saving Benefit Analysis

1. Adopt high-quality cold-rolled silicon steel sheet stacking; adopt special varnish dipping process and oven drying! It effectively reduces vibration and noise during operation; the introduction of new processes and new technologies such as high temperature resistant insulating material design makes the transformer more energy-saving and quieter. The energy-saving and low-noise coil is provided with ventilation slots for smooth air flow, which effectively reduces the coil temperature.
2. Products with outer boxes are all equipped with casters (below 100KVA), voltmeter, ammeter, cooling fan and temperature controller. The fan will start when the transformer temperature exceeds 70°.
3. During the operation of the isolation transformer, the primary coil and the secondary coil are not connected, but independent of each other. Therefore, the isolation transformer only has magnetic connection without electrical connection during operation. During operation, if the human body accidentally touches a single terminal of the output of the isolation transformer, there is generally no risk of electric shock. This is because the input and output of the isolation transformer are isolated from each other and not connected, which actually plays an isolating role. Therefore, the isolation transformer also has another name — safety transformer. (It is only safer for human body than autotransformer to a certain extent)
