Oil Immersed Power Transformer Core 
Industry Power Transmission Transformers 6kv 10kv 35kv on Load Tap Changing Regutation Electric Distribution Transformer
The core is beveled and stepped for maximum performance and minimal bulk. After the magnetic steel is produced by the cutting machine, it is continuously cut into specific lengths by the automatic stacking machine, and then automatically stacked. The correct size is ensured during the entire stacking and assembly process to ensure the high quality of the product.

Oil Filled Electrical Transformer Winding

Industry Power Transmission Transformers 6kv 10kv 35kv on Load Tap Changing Regutation Electric Distribution TransformerThe low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.
 

Product Description

On load tap changer transformer plays an important role in power system.It can not only stabilize the load center voltage, but also connect the power grid, adjust load current, improve reactive power distribution etc.Its basic principle is to lead out several taps from the coil on one side of the transformer, and switch from one tap to another through OLTC, without cutting off the load current.So as to change the effective number of turns and achieve the purpose of voltage regulation.

On load voltage regulation technology of transformer is widely used in distribution system, and also in step-up transformer of power plant. At present, almost all the large capacity transformers in the power system adopt on load voltage regulators,It is also equipped with a perfect low-voltage distribution network structure and sufficient reactive power compensation capacity to ensure  the safe operation of the power grid and meet the requirements of customers for power quality.

Oil Immersed Transformer Wiring Port:
High and low voltage wiring port with self locking nut.
Oil Level Measure Device:
Oil amount is clearly visble,red represents oil amount is
insufficient,blue represents normal.
Pressure Relief Valve:
Protect the oil tank from deformation or bursting.The water and air
outside the oil tank cannot enter the oil tank,and the inside of the
transformer will not be polluted by the air.
Off circuit Tap Changer:
It can be directly flxed on the cover or wall of the transformer,and can be tapped and replaced under no excitation state.
Gas Relay:
More sensitive sersing of changer in the internal gas of the transfomer to protect the transformer.
Oil Drain Valve:
Quick oil drain,reducing maintenance time,Convenient maintenance.

Product Feature

1.No load voltage regulating transformer need to adjust the tap of high-voltage side only when the power is cut off, 
so as to change the ratio of the transformer to regulate the voltage at the low-voltage side.Its regulation range is small, generally within ± 5%, It can only be adjusted once or twice a year.Most transformers in power system are no-load tap transformers.

2.The on load tap changing transformer has a special switch, which can change the tap position without power off (with load).Its voltage regulation range is large, generally more than 15% or even up to 30%, and it can be adjusted  automatically for several times a day.

3.No excitation voltage regulation refers to no-load voltage regulation,which can be adjusted only when the transformer is off.On load tap chaning transformer can change the voltage by changing the tap position when it is on running.

4.OLTC switch has the advantages of frequent on-off, no spark and long service life.The traditional trigger circuit of power electronic switch has the 
problem of electrical isolation.The application of optical fiber communication technology to the medium and high voltage trigger control system
 can effectively solve the problem of high and low voltage electrical isolation.



Advantage of materials
 
1.because we use oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
 
2.We use high-quality silicon-steel plates which are of lower unit loss, and no-load of the transformers is lower;
3.We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit;
4.We use thoroughly filtrated transformer oil containing less water ,gas and impurities, which makes our transformer work better;
5.We use high-quality rubber sealing material, which can prevent the transformers form aging or leakage;
6.All materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.
