SCBH15 Series

Amorphous Alloy Core Dry-type Transformer





SCBH15 series amorphous alloy core dry type transformer is an efficient and energy savingnew type distribution transformer. It is acombination of technologies of amorphous alloy transformer and cast resin dry typetransformer and has the advantages of oil free, flame retardant,self extinguish, resistant to moisture, anti-cracking, free maintenance, and especiallylow no load loss. It has been widely used in railway, airport,station, high building, business center, and industrial and miningenterprises. It is particular well suited to inflammable andexplosive places.


Characteristics

●Low loss

Especially no load loss, 75% lower than ordinarytransformer at the same capacity, drastically reducingits operating cost and has obvious effect on energy-saving.


●Strong anti-short circuit capacity

Three-phase five-limb structure and frameprotection structure around iron core effectively ensure the capability of anti-short circuit.


● Low noise

The combination of reasonable design and carefultechnique makes the noise of products lower than the requirement of nationalstandard JB/10088.


● Highhumidity proof  

HV&LV coils arevacuum epoxy cast resin, can be operated in 100% relative humidityand other harsh environment.


● Low temperature rise

Coils adopt thin resin structurewithout cracking and have strong ability for heatdissipation and overload.


● Flame resistance, self-extinguishment, explosion proof and no pollutionto environment

Glass fiber and other insulating materials used in coilsare self-extinguish and can not cause fire hazard because of electric arcproduced by short circuit.

Using Condition

●Altitude:less than1000m.

●Max.temperature: less than 40.

●Min.temperature: -5.

●Max.monthly average temperature: 30.

●Max.yearly average temperature: 20.
