 3 Structure
Careful use of high-quality cold rolled silicon steel core stack from the system, according to the different insulation levels, the overall level of impregnation of different insulation insulating paint, can effectively reduce the transformer noise, reduce the salt spray, mold and other effects on the transformer. According to the different degrees of protection, the transformer box is made from high quality steel, the structure of both the full account of air circulation, and can effectively play a protective role, the transformer is also very easy to connect the cable connection, the design is full of humanity. Voltage based on user requirements can be installed ammeter, power light, molded case circuit breakers.
