Description by Manufacturer

VPI(Vacuum Pressure Impregnation)

The coils shall be dried at atmospheric pressure in an over through which hot air is continuously circulated.

The totally dried ciiles shall be vacuum pressure imparegnated in polyester resin varnish.

The VPI process shall apply a one cycle polyester protective shield of varnish to the coils.

The VPI process shall effectively impergnate the coils assemblies, thus resulating in a unit shich is virtually impermeable to moisture, dust, dirt, salt air, and other industrial contaminants.

The VPI processed coils shall be permanently assembled on the core, and then dipped in polyerter resin varnish.

The varnish shall be cured on the core and coil addembly following an established temperature vs. time baking cycle in a hot air circulating oven.

Rating

Phase : Three, Single
Frequency : 60Hz, 50Hz
Primary Voltage : 22,900V and Below
Secondary Voltage : 120V thru 6,600V
Capacity : 10kVA thru 7,500kVA

Specification

Cooper Winding
150°C or special request 220°C insulation
AA, AA/FA
Only "H" Class
ANSI(IEEE), IEC, JEC, KS

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 temperrature 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 operatio, and it maintains outstanding stability under the drastic change of loading.

Environmentally Friendy

It has a little enironmental 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 meterial to cause on risk of fire, and there is no need of special inspection and repairing or mainrenance 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 VPI 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 abd efficient operaion 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 wher securing VPI that there is no partial discharge during the load operation.
