Product Description

Qingdao Electric oil distribution transformer includes hermetically sealed, amorphous alloy, conservator type and on-load tap changer type, which is usually pole mounted or installed in distribution station for daily lighting and factory power whose LV output up to 0.4kV. Our distribution transformer rating is up to 25000kVA, and primary voltage up to 110kV. The corrugated tanks as thermal expansion and contraction component enable the transformer oil completely isolated with the atmosphere. Oil distribution transformer with primary voltage range of 6,10,10.5,11,20,22,24,33, 35,38.5,66,110,121kV can be manufactured according to customer requirements.
 

Product Introduction

High efficiency, low loss, low noise, strong load resistance and long service life.

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.
 

SZ11-40000/110 has passed the short-circuit bearing capacity and all routine type tests.
 

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.

Applications

1.  No Partial Discharge: Actual measured partial discharge is less than 50pC, lower than the background noise.

2.  High Efficiency and Low Loss: Innovative core and coil design, along with leakage magnetic flux control technology, effectively reduces additional and stray losses.

3.  Low Noise: Actual measured noise is below 60dB, significantly better than the national standard noise levels.

4.  Intelligent Design: Meets the operational requirements of intelligent substations.

5.  Maintenance-Free Design: Comprehensive design includes air self-cooling methods, fiberglass dry-type bushings, and metal corrugated internal oil-type conservators, free of routine on-site maintenance, making it suitable for unattended substations.

6.  Compact Structure Design: Adopt the industrial advanced 220kV end inlet method, resulting in a compact overall structure, facilitating easier transportation and on-site installation.

7.  Strong Short Circuit Resistance: Utilizes foreign short-circuit mechanical force verification procedures and ensures all assembly stages of the transformer body meet design requirements.

8.  Over 15-Year's Design Life: Unique high-temperature-resistant hybrid insulation system based on temperature field simulation analysis, ensuring all transformer components have the same design life as the transformer itself.

9.  Passes All Routine and Type Tests at Once: The transformer's overall performance reaches advanced domestic levels.

Service environment:
1. Ambient temperature: Maximum +40ºC, Minimum -40ºC.Parameters can also be customized according to the customer's environment, such as long-term stable operation in a 55 ºC desert environment
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
