※ What is the Disaster Prevention Dry-Transformer?
 
Disaster Prevention Dry-Transformer is suitable for standard of international environment (IEC60076-11) F1, C2, E2 test that regulates amount of poisonous gas, visible distance with smoke transmissivity and highest temperature of flame. This is reliable transformer that protects life and property in the event of fire. It is also possible to recycle 97% of the waste resources to prevent environmental pollution.
 
※ IEC 60076-11 Test
 
- F1 (Fire Behavior test)
A test to determine the volume of harmful gas, sight security (transmission factor), and maximum flame temperature when transformer in fire.
 
- C2 (Climatic test)
Perform heat impact test to raise the temperature from –25℃ modified to 2 times of rating current.
No appearance damage such as tracking found in insulation test performed at 80% (40kV) of standard test value(50kV).
 
- E2 (Environment Test)
No abnormality found in the insulation test leaving it in a chamber with 93% of relative humidity for 6 hours or longer.
In addition, no appearance damage found such as tracking in moist penetration test for 144 hours.
 
※ Feature
High Level of Safety
By using the non-inflammable insulation materials, it has small volume, and when a fire breaks out, it has no toxic gas releases that it minimizes the damage to the valuable life and property damage.
 
High Reliability
It uses the insulation material(NOMEX) that is strong against high temperature and it prevents the deterioration in overload and accidents from high temperature by the high frequency to have the high reliability and extended service year for the transformer.
 
Increase Emergency Overload Capability
By using 220°C insulation material that is more outstanding than "H" Class type insulation material with the thermal resistance limit of 180°C that there is no life shortening and accident arising for transformer at the excessive loading above the rated capacity.
 
No Cracking
There is no epoxy resin layer on the coil that there is no crack from the expansion and contraction under the loaded operation, and it maintains outstanding stability under the drastic change of loading.
 
Environmentally Friendly
It has a little environmental pollution in production or in disposition, and it is available for resource recycling.
 
Low Noise &Easy Maintenance
The size of the core is less that the noise is relatively low, and the use of non-inflammable insulation material to cause on risk of fire, and there is no need of special inspection and repairing or maintenance for long time of use.
 
Small Size &Light Weighted
With the use of high temperature insulation material, the design technology realizes the slimming of the disaster prevention transformer.
 
Space Utilization
The stability is high without the limit in installation place due to the operation problem that it can be installed near to the load equipment that the loss on line is small add efficient operation possible.
 
Designed To Be Free Of Partial Discharge
The design is made with the higher insulation standard than the partial discharge commencement voltage, and there is no possibility of inflow of vapor where securing V.P.I (Vacuum Pressure Impregnation) that there is no partial discharge during the load operation.
 
※ Advantages of 3D Core Type
-High Efficiency & Low noise.
-Improving short-circuit characteristic.
-It can be reduced by more than 30% over than the existing footprint.
-Highly efficient core.
