Multi transpose rectifier transformer winding was designed according to the users' requirement, capacity is 250~6300kVA, the total impedance is 0.05; transformer efficiency is above |
|
| "98.5%. It uses class H insulation system. It has varied structural appearance and simple appearance, its size and shape can be determined according to the user's requirements. To meet user's requirements in the installation, SUNEL made the transformer smaller and more efficient as she can. |

SUNEL's Energy-saving Miniaturization Substation Precinct dry-type transformers finally emerged. Block held shocked by its precision, sophisticated design and high efficiency technology. In the time that |
|
| everything is in a crowded, SUNEL said: "less brought more.” So she uses transformer's compact construction manufacture a greater useable space. In the time that resources is limited, SUNEL said: “reform brings smooth, smooth brings future.” So she uses the most remarkable frequency technology to save more energy consuming for enterprises. |

It has the specialty of Small volume、little weight、safety、high grade electrical insulation、strong overload capability and enviornmental protect. Compared with epoxy-resin, less Overproof |
|
| Problemof No Load Current and Loss in Transformer, turely achieved the commitment that without fans it can overload 20%,turely show the advantage and hihglights of SG10 series. |

The core adopts high permeability cold rolling grain-oriented silicon-iron sheets, 45° inclined step-by-step seam welding, and the core is of special square-tube drawplate structure, the core stem is |
|
| bound up with insulation tape. The core surface is applied with special resin to prevent damp and rust, and its open-circuit loss, no-load current and core noise are all significantly lowered. |

SG(B)10 dry-type transformer winding insulation adopts American DuPont NOMEX paper insulated material, immersed in “H”Grade Nonsolvent Insulating Coat by VPI equipment, |
|
| solided by high temperatures Oven-drying. Safety fire-retardance、nontoxic and anti radiation, even if fire fighting occurred, no toxic gas will be released; This product has no cross reaction with solvent, good tolerance of acid and base |

Magnetic Voltage Regulator has the specialty of smooth OLCT、easily orperation、remarkable energy saving、good stability of system、Strong Ability of Preventing Interference、easily opened |
|
| loop hand operation and achieved closed loop outomatically with different signals. This product is also suitable for outomatically hot-working、heat-treatment、plating、Speed-Adjusting System，as corollary Voltage-conditioning Power Source. Now widely used in Salt Bath Furnace、Vacuum Furnace、Electroslag Remelting Furnaces、Glass Electric Melting Furnace、Monocrystalline、polycrystalline crystal、cracking furnace and all kinds of Electric Resistance Furnace. |

This product is contrapose to the design of corollary Si-Mo Rod transformer, suitable for power source isolated low-voltage output. Si-Mo Rod electrothermal body electrical resistance increases with |
|
| the rise of temperature. When it start to heating, the electrical resistance of electrothermal body less, need low-voltage, about one-third or one-fourth of the working voltage. According to the working voltage, electrical resistance and of Si-Mo Rod electrothermal body. |

 |
Whatever test、heating, all have to upward flow by electrical depressor, makes low-voltage current to several thousands of Ampere. The high voltage of this series product is 220v、380v and |
|
| 650v in common, the low-voltage is up to the upward flow. It is a special series can be used in industrial and mining enterprises. When using this product, generally need add voltage adjustment before electrical source, make the low-voltage to stepless adjustment. This series product's high-voltage coil is generally cylinder type, low-voltage is generally helical winding coil made by bare copper, high-voltage is generally without OLTC, Voltage of low-voltage winding transformation is reached by series and parallel. |

The quality and the mechanical, chemical properties of tools and machine parts, to a great extent, are related to the heat treatment process. Now, heat treatment by salt bath furnace are widely adopted |
|
| by machine manufacturing industry to improve the quality of products. ZUDG、ZUSG type salt bath transformers are specially used to supply the source voltage of such furnaces. |
|

This product is contropose to the design of corollary Silicon Carbide Rod furnance, is suitable for the electrical insulation. In the process of using Silicon Carbide Rod heating element, electrical resistance |
|
| increases with the using time, this phemomenon is aging effect. Rod electrochemical should regarded as normal phenomenon, it will result in the reduction of temperature, in order to work normally, extend the Silicon Carbide Rod Transformer working life by ajusting output voltage to content the working voltage, the rank of adjustment is 2-3 times. |
