>Technical support: Over the years, our company has used high-quality materials and advanced technology to produce 1kva-3000kva, SD / SG (YSD) series single-phase, three-phase dry-type mechanical equipment special transformers. The products refer to the latest research and development of similar products of Siemens company. The products meet the international and national standards of vde0550, iec439, jb5555 and gb5226. SG series three-phase dry-type transformer not only has the function of voltage transformation in the power grid, but also can isolate the third harmonic of the equipment from the power grid, protect the heat generated by the machine and reduce the service life of the insulation materials. It is especially suitable for imported equipment (380V in → 220V out, 380V in → any voltage output, 220V in → any voltage output) with specifications between 1kVA and 1000KVA. SG and DG series dry-type isolation transformers are widely used in various three-phase power supply occasions with AC 50 ~ 60Hz and input and output voltage not exceeding 500V. It is widely used in AC 50, 60 Hz, input and output voltage not more than 500 V in various power supply occasions. All kinds of input and output, voltage level, connection group, tap position adjustment, winding capacity distribution, secondary winding configuration, whether shell is required or not, are carefully designed and manufactured according to the requirements of users.

Overview (low loss type three-phase dry type safety isolation transformer, H class, 180 ℃ insulation class)
The transformer is the main component of various power supply and electrical equipment. The isolation transformer is composed of cylindrical winding and laminated iron core. The iron core is laminated with new high-quality silicon steel sheet and fully inclined joint. The company adopts advanced manufacturing technology, including imported Max high-speed automatic winding machine and a complete set of vacuum pressure impregnating equipment; the winding adopts the method of whole line winding without tire; the transformer is vacuum impregnated to make the insulation grade of the transformer reach grade f or H. The output and input voltage of the transformer can be designed according to customer requirements. There are single-phase, three-phase or multiple input and output specifications.
A kind of
>Description of transformer material configuration:
① Iron core
The new high-quality silicon steel sheet is adopted. The main material is 0.35-thick h18, h14, H12, Z11 high-quality silicon steel sheet. According to the requirements of guest rooms and service conditions, we select the most appropriate material to achieve the best performance design of transformer. (the conventional material is new high-quality silicon steel sheet).
② Wire rod
Pew, UEW, EIW, seiw, FEAI enameled wire and glass wire are used. The temperature resistance grade is f (155 ℃), H (180 ℃), HC (200 ℃), C (220 ℃). (the conventional temperature resistance grade is H class 180 ℃).
③ Insulating materials
Using high temperature resistant insulation paper as insulation material, it has multiple properties of high temperature insulation, flame retardant and moisture resistance.
④ Insulation material terminal block
Small power terminal block, beautiful appearance, excellent pressure resistance, temperature resistance, flame retardant performance. High power copper bar is used.
⑤ Iron foot
CNC bending cold binding plate is mainly used, and environmental protection electroplating such as multicolor (golden yellow), blue zinc (silver white), white zinc (ivory white), surface anodizing (black) can be selected.
