Product Description

110KV~220KV Power transformer

   High pressure transformer ,use Japanese Toshiba analysis software and our company special calculation and validation procedure. In order to ensure the performance of product, we design and test to the transformer core, coil, the body of machine, lead wire, oil tank and other parts of machine.
 
   Our product SSZ11-40000/110 has passed the short-circuit bearing capacity and all routine type tests of the National Transformer Quality Supervision and Inspection Center.
 
  This product has the characteristics of stability, economy, reliability and environmental protection, and is suitable for power plants, substations and large industrial, mining and petrochemical enterprises.
 
Oil Immersed Power Transformer Core 
Substation Transmission Three Phase Step Down Power High Voltage Oil Immersed Electric 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

Substation Transmission Three Phase Step Down Power High Voltage Oil Immersed Electric 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.

Transformer Test

Substation Transmission Three Phase Step Down Power High Voltage Oil Immersed Electric TransformerTransformer ratio and connection
Measurement of load losses and short circuit impedance.
Measurement of no-load losses.
Separate source withstand voltage test
Induced over-voltage test
Temperature rise test
Lighting impulse withstand voltage test
Measurement of partial discharge
Other transformers like rectifier transformer are also available on request.
 

Product Feature

1 - Low loss, low noise, low partial discharge, low temperature rise and energy-saving
2 - Adopt the latest insulatoin structure
3 - Excellent anti-short-circuit ability.
4 - As to the heat dissipating element adopts corrugated sheet or sheet radiator and other components.
5 - The iron core adopts high quality cold rolled graind oriented silicon steel sheet ,it is low loss and small magnetostriction.The whole iron core adopts the structure of 45-degree full oblique joint and round cross-section, which will not be loosened due to vibration during transportation and operation.

Oil immersed transformer ,use Japanese Toshiba analysis soft ware and our company special calculation and validation procedures to make sure the performance of products. Superior process equipment ,elaborate material selecting and efficient manufacturing make the transformer have small volume,light weight,low loss,low partial discharge,low noise characteristics.
The product is stable,reliable,economic, environmental protection.It can be applied to many places such as power plants,transformer substation ,large industrial mining and petrochemical enterprise and so on.


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.
Advantage of technology


Temperature control device:
The transformer adopts the BWDK series signal thermometer. The temperature measuring element is embedded in the upper half of the low-voltage coil, which can automatically detect and display the respective working temperature of the phase coil, and has the function of over temperature alarm and trip.
