oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full
sealed/double winding
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.
Compared with common oil-immersed transformer ,it is unnecessary
for full-sealed transformer to be equipped with oil conservator and
change in oil volume is automatically adjusted and compensated by
elasticity of corrugated sheet of corrugated tank , and transformer
is isolated from air to prevent and slow down oil degrading and
insulation aging, enhance operational reliability, with normal
operation and no maintenance.
Features & Advantages
1. Product maintenance is simple.
2. The low voltage is wound by copper foil, so that the electric
field of the transformer is evenly distributed. The low-voltage
inner frame is formed by forming a hard paper tube, and the
high-voltage outer half-layer is layered with a layer of glass
adhesive tape. The compacting block is laminated wood. The
mechanical strength of the transformer and the vacuum oil injection
of the transformer can completely eliminate the air bubbles in the
coil, thereby improving the overall resistance of the transformer
to sudden short circuit.
3. The box is made of stainless steel bolts for a beautiful
appearance.
4. The fuel tank adopts a fully sealed oil tank to isolate the
transformer oil from the air, slow down the aging of the
transformer oil, and the molded parts are molded parts to enhance
the reliability of the transformer seal.
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
