SG(B)10, 11 series non-encapsulated H-grade dry power transformers
This product is a high-performance, high-safety, environmentally friendly dry transformer developed independently by our company based on American DuPont NOMEX paper and referencing German MORA technology. It is suitable for harsh environments with high fire protection requirements, large load fluctuations, and dirty, humid conditions, such as airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated residential areas, as well as special environments like petrochemical industries, nuclear power plants, and nuclear submarines.

Product Description
Overview
This product is a high-performance, high-safety, environmentally friendly dry transformer developed independently by our company using American DuPontNOMEXpaper as the base system, referring to GermanMORAtechnology. It is suitable for harsh environments with high fire protection requirements, large load fluctuations, and dirty, humid conditions, such as airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated residential areas, as well as special environments like petrochemical plants, nuclear power stations, and nuclear submarines.
Performance Characteristics
- Good heat dissipation conditions, long thermal life, extremely strong overload capacity. Under120%long-term overload conditions without forced air cooling, it can operate at full load for a long time.IP45Extremely high safety and flame-retardant performance; no smoke is produced under high-temperature combustion at
- °C.800Extremely strong thermal shock resistance (immediate full load at -50
- °C)100% waterproof sealing, excellent hydrophobicity and moisture resistance.Unique coil structure and strong field calculation make the product almost free of partial discharge.
- Low loss and significant energy-saving effect; compared to series dry transformers, no-load loss is reduced by an average of
- 20%,
- load loss is reduced bySC95%.After the service life, the insulation materials and copper wires can be easily separated and recycled without polluting the environment.Structural FeaturesUnique ceramic insulation structure using our company's insulation tubes and high-frequency ceramic pads that never deform.High and low voltage coils are first insulated with materials and then impregnated multiple times with a special formula of H-grade insulation using VPI vacuum pressure equipment.
- After multiple baking processes, they are sealed with high-strength insulating materials and cured at high temperatures. The high-voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation conditions.
The core is made of imported high-quality silicon steel sheets with high magnetic conductivity stacked in a step-type progressive structure. The winding and core use elastic fixing devices to give the transformer lower no-load loss and noise. The core surface is treated with a special process. The core is moderately clamped by tensioning screws; the upper and lower clamps are connected by plates and fixed to the base and windings as a whole. The windings are fixed by elastic pads; the buffering structure can reduce the vibration level of the windings and lower noise.
- The lead wire terminals are fixed at the upper part of the windings; the tap winding is in the middle; the low-voltage terminal is a plate-type conductive busbar using cold pressure welding.MOR
