3-phase Dry-type Transformer
Our 3-phase dry-type transforms are mainly used for controlling power and power supply of various high and low voltage electrical equipment, import and export equipment, precision machine tools, UPS, electroplating, lighting, heating, communication, chemical industry and other industry equipment. It has the advantages of small size, light weight, simple maintenance and reliable operation.
Overview
Standard
Conform to the standards of B/T 9646-1999, GB 19212.5-2006, GB 1904.11-2007.
Technical & craft characteristics
The core is made of high-quality cold-rolled silicon steel sheets.
According to the insulation level, it is impregnated with insulating paint of the corresponding insulation level to effectively reduce noise, salt spray and mold.
The box is made of high-quality steel plates. The structure fully considers air circulation and can effectively play a protective role.
Convenient connection of wiring cables.
Voltage and current meters, power indicator lights, molded case circuit breakers, etc. can be installed on request.
