oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
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.
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.
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
