Tap Changing S10 Oil Immersed Power Transformer ONAF 110KV Off Circuit

Electrical 110kV Three-winding Off-circuit Tap-changing Transformer

The core of 110kV power transformer is high quality silicon steel, with several layers lapped. It is low-loss, low-noise, and anti-shortcut etc. Now it is wildly used in power station, power plant, and gets high praise from these users.

1 Low noise

Use of high-quality core silicon steel,

Core STEP stepping joints,

Reduction of the flux density, despite of the increase of cost,

Use low-noise fan as the air cooling equipment,

Increase the shock absorbing measures,

Well interior- protection, to avoid direct rigid contact of the body and the tank.

2 Maintenance-free

Our company adopts the domestic leading technology, use fully enclosed structure for the transformer oil tank, ensuring product life of 30 years, and maintenance-free operation.

3 Technology Features

Use high-quality oxygen-free copper wire for the coils, choose adhesive - type transposition wire, to improve the overall strength. With accordance to design needs, coil (especially low-voltage, voltage regulator) can be winded on hard paper tube, the appropriate increase in the number of stays among the coil, will enhance the mechanical strength of the coil.

For the coil assembly structure, we use the standard structure of Tianan power transformers, with accordance to the design program result, cooling and insulation structure like oil separator can be placed inside the coil, to guarantee its superior reliability.
