230-242kv on-load-tap-changing power transformer is made of high-quality silicon-steel sheets, and laminated by steps. It is advantageous in low loss, low noise, low voltage partial discharge and high anti short-circuit capacity. The dynamical and thermal stability of this transformer, of which the coils are winded by high-quality oxygen-free copper wire as well as used pre-compressing brackets processes and interior and exterior structure. The transformer tank used wave form shell, has very nice appearance, the core is with d shape yoke and 45 angle seaming. The core and oil box are well fixed and well protected on moving.
The core of 110kv power transformer is high quality silicon steel, with several layers lapped. It is low loss, low noise, and anti-shortcut etc. Now it is wildly used in power station, power plant, and gets high praise from them. In 1997, sfsz9-31500/110 on-load voltage-regulated transformer has passed the test by ministry of mechanical industry.

35kv grade transformer is with the following characters: low loss, low noise, protection for thunder and lighting, and anti-shortcut capacity, beautiful appearance etc. It is made by advanced assembling lines and method, with qualified parts. It is with for remote functions: remote communication, remote test, remote adjustment, remote control. By remote control from a computer, the power station could be free from supervision in the office. Type "9" 35kv grade series energy saving transformer has passed the test by national mechanical and industrial bureau, and national power group. 35kv grade series transformer mainly use in power network, and the projects of power distribution.
Main functions and characters
• core is with advanced three steps: vertical and horizontal and horizontal cut, lap and multi-stage. It disperses the air distribution, improve the magnetic path. Decrease the empty loading loss, current and noise.
• core with dragged panel, pressed the coil, particular glue for silicon steel; a set of measures to increase the mechanical strength.
• new structure of high and low voltage wrapping, reasonable arrangement for oil tube and connection, increase the capacity of mechanical strength and anti-shortcut.
• oil box is bell type or core suspension type, the wall of oil box is as wave form.
New 39 series three phased oil-immersed transformer uses new structures of insulation and anti-shortcut etc. Its features are advanced internationally. Comparing to s7 series, the empty loading loss decreases 10.25% in average, empty loading current decreases 37.9%, loading loss decreases 22.4% in average, it is the upgraded version for energy saving.
Main functions and characters
• low loss, energy saving visible;
• core is in round form, multi-stage, and entire tilted three stages seaming and lapping structure;
• high and low voltage coils are wrapped with oxygen free copper coil. All high voltage coils are made with several layered bucket structure.
• reasonable structure
• new parts and new fixing parts
• high voltage coils are wrapped with polyester enameled wires, filled with glass fiber, and then resin under vacuum condition. It becomes solid under high temperature. It is with high mechanical intensity, low discharge partly; low voltage coils are wrapped with a whole piece of copper foil, with strong anti-shortcut capacity. The core is made of silicon steel. By reasonable choosing magnetic density, decrease the empty loading loss effectively
• fire protection, anti-explosion, and no pollution
• coil is free from humidity, low noise and capacity of heating dispersion
• low loss, energy saving, free from maintenance, small volume, light, and easy for installation

Alfo manufacturing aluminium foil wound transformers in india.
We alfo electric, manufacturers of power conditioning equipment and instrumentation and control equipment for energy management. This position of market leadership has been enabled by providing greater value to the customer through accent on value engineering resulting in better quality and reliability at a lower cost.
One of the major impact areas of value engineering is in the use of aluminium foil wound transformers, as our power conditioning range of products had a high copper content, the possibility of reducing our dependence on copper due to its relative high cost and price instability was considered. This resulted in our using aluminium foil wound transformers in place of copper wire wound ones.The aluminium foil wound transformers so developed have been successfully used in stabilisers and isolation transformers are working on the field since 2007. As this manufacture involves a convenient and efficient method of winding the foil around the core, we designed and developed the special purpose cnc foil-winding machine. We introduced this unique construction technology, providing practical and economical aluminum foil-wound transformers in the 1 kva to 500 kva power range.
