315KVA oil immersed transformer is widely used as a wide range of facilities. It has great significance for energy saving and emission reduction. 315KVA oil immersed transformer is the main selection product of distribution equipment at present, and the energy saving effect is remarkable. The S11 type distribution 315KVA oil immersed transformer manufactured by our company all use the 30P series high magnetic conductive silicon steel produced by Baosteel in Shanghai. The foil coil coils and new insulation materials and processes are adopted. The design of high temperature resistant, impact resistant and full sealing structure ensures the stability of the quality of 315KVA oil immersed transformer oil, prolongs the maintenance period, and at the same time, it is composed of corrugated sheet radiator. The tank is made of phosphating and multi-layer anti-corrosion spraying process, and has good weatherability.
Long service life and maintenance free operation. The fully sealed 315KVA oil immersed transformer box cover and the box edge are bolted or welded to the structure. The contact between oil and air will be isolated. The insulation will not be dampened, greatly reducing the aging rate of the insulation and improving the service life. The design is compact and the running noise is low. Because of new materials and new technology, noise reduction and no oil storage cabinets are less expensive than similar products. No oil changing is needed during normal life period, which improves the safety and reliability of the network operation. The corrugated oil tank is small in volume and beautiful in appearance. The oil tank of S11 315KVA oil immersed transformer is cooled by corrugated sheet. When the oil temperature changes, the change of oil volume is regulated by the elastic expansion and contraction of corrugated sheets. No hanging core and oil detection. When the 315KVA oil immersed transformer is packaged, the vacuum filtration and oil injection process is adopted to completely remove the moisture in the oil of the 315KVA oil immersed transformer. After sealing, the 315KVA oil immersed transformer is not contacted with air inside, effectively preventing the insulation performance of oxygen and water entering 315KVA oil immersed transformer.

It is widely used in mechanical equipment, transportation, post and telecommunications, military, railway, import and export equipment, research and culture fields, such as large mechanical and electrical equipment metal processing equipment, production lines, construction equipment, elevators, medical equipment, embroidery and light textile equipment, air conditioning, radio and television and household appliances, lighting and other places that need pressure transformation.
The oxygen free copper wire with lower electrical resistivity and a series of additional surface treatments are used to make the 315KVA oil immersed transformer less load and more reliable in electrical performance.
With high quality silicon steel sheet and silicon steel sheet with lower unit loss, the load loss of 315KVA oil immersed transformer is lower.
Use high quality laminated wood insulation parts, no cracking, enhance the mechanical strength and dynamic and thermal stability of the body.
315KVA oil immersed transformer oil with deep filtration and lower water content, gas content and impurity level are selected to increase the insulation performance of 315KVA oil immersed transformer.
High quality rubber sealing material is selected to effectively prevent aging and eliminate leakage.
All raw materials are inspected strictly according to IS09001 after quality inspection of raw materials.
315KVA oil immersed transformer oil tank adopts a fully sealed structure. Compared with the ordinary oil immersed 315KVA oil immersed transformer, the fully sealed 315KVA oil immersed transformer is cancelled. The oil storage tank's wave wings replace the oil pipe as the cooling and cooling element. The corrugated oil tank is made of high quality cold rolled thin plate on the special production line, and the wave wing can bear the volume of the 315KVA oil immersed transformer. Therefore, the 315KVA oil immersed transformer can be isolated from the atmosphere to prevent and slow down oil deterioration and insulation damp, enhance operational reliability and maintain normal operation.
The surface of corrugated oil tank is painted with anti corrosion, rainproof, moisture-proof and anti salt fog after deoiling, rust removing and phosphating. It is suitable for use in metallurgical, petrochemical and mining environments.
