S11 12KV 30-2500KVA 3 phae Oil-immersed transformer
Product Description
S11 full-sealed oil-immersed power transformer developed by the
company has the advantages of low loss,low noise and high
efficiency and can achieve good energy-saving effect and reduce
pollution.
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
