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. Packed in wooden case
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. Main functions and characters: • bell type tank and the wave form shell.; increase the strength of oil box, beautiful appearance; • core is with d shape yoke, 45 angle seaming; • core and oil box are well fixed and well protected on moving; • reasonable wrapping method, in the interior and exterior structure of coil; use support; hard paper bucket between coils increases the capacity of anti-shortcut; • advanced assembling method such as cold pressing and welding technology, installing with sets of coil, paper bucket production. Packed in wooden case
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. Packed in wooden case
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 Packed in wooden case
