electrical power transformer
110kV - 8000kVA , Power Distribution Transformer , Three Phases , Power Transformer , Hight Capacity
The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, enable the effectiveness of reducing no-load loss and no-load current.
HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.
LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.

4.1 Pay attention to the follows while transporting:
l Weight, size, hanging height, etc. can be found in the reference drawings.
l If flatbed truck is used for transporting, should check its loading record in the past.
l Fix the transformer body on the flatbed truck with rope through fixing holes. Refer to reference drawings for the locations of those holes.
l Attention! There is special axis for hanging and pedestal for hoisting jack. Use them while hanging and carrying the transformer, no use with other places.
l The ropes must be long enough to ensure the hanging angle is less than 30 degrees. Balance girder should be used due to limit of space height.
l Only the special holes can be used while the transformer is being haled. No for ramp with gradient over 15 degrees or speed exceed 20km/h.
Different parts should be used for different carrying methods (such as hanging, hauling and moving). They are shown as follows:
|Hanging axis||4||On the lower tank||Full hanging|
|4||Bottom of the tank||Bi-directional traction or moving|
|Traction hole||4||Lower part of the tank|
|Jack block||4||Body of the tank||Hydraulic lifting|
Attention: Where transporting, don’t damage the buildings.
