Product Description

product description

Our company has used high-quality materials and advanced process technology for many years to produce SG series three-phase dry-type transformers between 160V and 600KVA, which are the latest research and development transformers for CNC systems by our company with reference to similar products from Siemens, especially those between 160VA-16KVA. Three-phase dry-type transformers, whose appearance and installation dimensions have been standardized, are common with Siemens 4AP series, and the products conform to VDE0550, IEC439, JB5555, GB226 and other international and national standards.

SG series three-phase dry-type transformers are widely used in various three-phase power supply occasions of 50~60Hz and input and output voltages not exceeding 3300V. Generally ±5%), the distribution of winding capacity, the configuration of secondary single-phase windings, the use of rectifier circuits, whether it is required to have a casing, etc., can be carefully designed and manufactured according to user requirements.

ZSG series three-phase dry-type rectifier transformers are used for rectification equipment, charging, voltage regulation and DC power supply after rectification.

SG three-phase dry-type isolation transformer SBK three-phase dry-type transformer structural characteristics

The iron core of the SG series three-phase dry-type transformer is made of high-quality cold-rolled silicon steel sheets. According to the different insulation grades, the whole is impregnated with insulating paints of different insulation grades, which can effectively reduce the noise of the transformer and reduce the influence of salt spray and mildew on the transformer. . According to the different protection levels, the transformer box is made of high-quality steel plate. The structure not only fully considers the air circulation, but also effectively plays a protective role. The transformer wiring cable is also very convenient to connect, and the design is full of humanization. Voltage and ammeter, power indicator, molded case circuit breaker, etc. can be installed according to user requirements.
