Performance characteristics

1. Oil-immersed transformer low-voltage windings in addition to small capacity with copper wire, copper foil are generally used around the cylinder structure; high-voltage winding multi-layer cylindrical structure, the ampere-turns of the winding distribution, leakage magnetic Small, high

mechanical strength, anti-short circuit ability.


2. The core and winding their own use of fastening measures, height, low voltage leads and other fastening parts are with self-locking lock nut, using the structure does not hang the heart, can withstand the transport of Britain.


3. The coil and the core vacuum drying, transformer oil vacuum oil and oil filling process, the moisture inside the transformer to a minimum.
4. The fuel tank using corrugated sheet, it has a breathing function to compensate for the temperature change caused by the volume of oil changes, so the product does not conserve oil tank, obviously reducing the height of the transformer.


5. Due to the corrugated sheet to replace the conservator, the transformer oil and the outside world, thus effectively preventing the oxygen, water and lead to the decline in insulation performance.


6. According to the above five performance, to ensure that the oil-immersed transformer in normal operation does not require oil change, greatly reducing the transformer maintenance costs, while extending the life of the transformer.

 

Application
This product is widely used in urban and rural power grid construction and renovation projects. This product is especially suitable for areas where there is insufficient power and load fluctuations and where daily maintenance is difficult. Because the transformer adopts a fully sealed structure to prevent the transformer oil from coming into contact with the air, it can operate in a humid environment and is an ideal power distribution equipment in urban and rural distribution networks
