Features of 33/11kv Series Power Transformer
The three-phase oil-immersed transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheet; the high-voltage windings are made of high-quality oxygen-free copper wire. It has a multi-layered cylindrical structure; all solid parts are specially secured against loosening.
The product has the characteristics of high efficiency and low loss, which can save a lot of power consumption and running cost, and has significant social benefits. It is a new technology product promoted.
•Unique Welding Process, No Leakage
Eliminate the high and low pressure risers to reduce welds; the fuel tank wall uses wide-width steel plates to reduce joints; a unique welding process to ensure welding quality.
All sealing flanges are grooved to ensure sealing performance.
All the oil drain valves of the transformer are made of copper valves, and the radiator uses a vacuum butterfly valve to reduce the leakage of the transformer.
•Low Loss, Low Noise
Adopt domestic and foreign advanced technology and equipment, professional research and development. The core adopts high-performance cold-rolled oriented silicon steel sheet and fully automatic robot lamination machine with small shear burr and low lamination coefficient, which effectively reduces the no-load loss, no-load current and noise of the transformer. The no-load loss is 5% to 15% lower than the manual lamination.
The transformer is equipped with an oil surface thermometer, the top of the fuel tank is equipped with a pressure relief valve with a contact point, the oil level indicator of the oil storage cabinet is an oil level gauge with a contact point, and the high and low pressure casing is an anti-fouling enhanced pure porcelain oil type casing, which can be used for Heavy pollution level environment.
•High Quality Insulated Skeleton Support inside the Coil
The inside of the coil is supported by a high quality insulating skeleton. All coils adopt inner and outer struts, all struts and blocks are chamfered, the electric field is uniform, and the reliability is enhanced. All fasteners on the axial body of the coil are self-locking locknuts, so that the product can withstand long-distance transport bumps without looseness and without the need for a lifting core.
