Quick Detail: High Voltage 12KV 3 Phase AC Intelligent Circuit Breaker For Substations
220kv,110kv and 66kv low loss series transformer if our independently developed new generation of transformer
on the basis of absorption of domestic and foreign advanced technology,which features low local discharge ,low loss,
low noise,high reliability ,strong protection against abrupt short circuit,its excellent performence has been recognized
ny wide users and high appeaised by experts.the full sealed suspending cover free product sell well nationwide.
Amount of local discharge :the apparent discharge amount under 1.5 times if rated voltage is less than 80pc.
Noise:product of 63mva and below is lower than 58db(an)
Power loss:no-load loss is 30% lower than that of IEC stanard.
Reliability:all in service product have no damage or oil leakage occurred;
Short circuit withstanding :model SFZ11-50000/132 smoothly passed the short circuit withstanding test of the
national transformer quality supervision and inspection center and also passed holland KEMA quality control systom.
The high voltage aoil adopts an interleaved continuous structure to improve the voltage characteristica under impact
voltage and make voltage evently distrivuted.all stays and pads are chamfered to keep highly reliable insulation.
In the transformer winding there is a zigzag oil guide structure so as to fully cool all areas inside the winding ,lower
the temperature rise of the winding and the hot points of the winding and [rolong the service life of insulation.the HV
and MV regulation system are independently provide with voltage regulating winding to balance the ampere turn of
each winding effecticely lower the axial electrodynamic force generated at short circuit of transformer and improve
abrupt short circuit withstanding capacity.
The winding adopts radial 0 margin design ,between the core and the paper sleeve of LV winding ,and between the
LV,HV,voltage regulating windings ,as well as before insertion of stays and shround plate they are fully dried and
tightly matched to ensure extremely good compactness and concentricity of the entire winding.
The core is made of high permeable grain orientated top quality coid rolled silicon sheet and the materical is cut with
advanced germany geoge gmbh automatic shear line with the cut burrs controlled within 0.002mm.
The sillicon sheet fabrication adopts no-upper yoke lapped technology and all lapped joints of the sillicon sheet are 45
full miters.the laminated core sheets are integrally pressed and adhered with epoxy resin to make the three leg two
yoke core a strong and flat integral one with good verticality precision ,this effectively improves no ;oad performance
and reduces noises.
Bracing plates are used as support between coil leg and inner coil.the iron yoke is tied with wpoxy resin impregnated
glass fiber band,and the lower iron yoke and the lower section of oil tank is tightened with counter pressure bolts.the
upper iron yoke and the upper section of oil tank are fixed at 3 locations .hence the body inside the oil tank can withstand
the vibration during transportation without any shift.
OIL TANK AND ACCESSORIES
The tank wall adopts wide steel sheet,which will be folded into corrugated structure without splicing,in this way welds
are decreased and mechanical strength id enhanced ,meanwhile ,the corrugated wall has deverging effect ,and thus
plays a role in dectease of noise .the routing troughs and control cabinets of the secondary circuit are all made of
stainless steel.so the entire transformer has a simple and good looking .
All sealing surfaces use quality sealing material and are precision machined.
On the edge of the tank there are double sealing grooves,and the outer sealing materical is used to shade the
atmosphere and ultra ray to protect the inner seaing being damaged,thus at utmost prolinging service life and
enhancing reliablity of the seal.
As we have good cooperation tie with many subassembly manufactures of famous transformer brands,we are able
to provide different subassemblies as per users requrments .the whole procedure of manufacture ,R&D and sales
services are carried out strictly in accordance with interational stanards and ISO quality management system.

1. Specific packaging can be made to order.
You can specify other shipping methods such as Airmail, FEDEX or DHL. We shall let you know about the
shipping cost after receipt of your order.And also can send by sea or air, kindly send me the port of yours.
The standard procedure for making wooden case is as follows:
Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100 engineers. We have special pre-sales engineer to work with customer at early stage of the project.
Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia, Peru,
Ecuador, Senegal, which will make a fast response for customer.
Warehouse and Emergency Supply
Warehouse and emergency supply for spare parts, damage parts and missing parts: DINGLI has built production line
in Quito and warehouse for transmission line and distribution network in Ecuador, Bolivia and Senegal with common use spare parts.
Clients of Bolivia visited Dingli for factory inspection, we talked about the key issues faced right now, and found
ways to solve it together. They set a high value on this cooperation.
