oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
Product Description
The S11 series oil-immersed transformer is a traditional structure with compact structure and high reliability transformer products. This series of products uses a fully sealed fuel tank to isolate the transformer oil from the air and slow down the aging of the transformer oil and insulation. This series of products uses traditional materials, compact and energy efficient products.
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.
High-quality material
a. The three- phase oil-immersed Power Transformer applies new type
insulating structure.
b. The iron core is made of high-quality cold-rolled silicon-steel
plate 27ZH10.
c. All fasteners have been processed with special trearment to
prevent them from loosening.
d.Oxygen-free copper lines of lower resistivity, which will become
smoother and burr-free after series of additional surface
treatment, so the load loss of our transformer is lower and the
electric performance is better.
e.High-quality wooden laminating insulation pieces, which won’t
split or move even under the influence of short circuit.
f. Thoroughly filtrated transformer oil containing less water, gas
and impurities, which makes our transformers work better.
h.High-quality rubber sealing material, which can prevent the
transformers form aging or leakage.
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
