Zhejiang Jiangshan Transformer Co., Ltd

We offer oil immeersed transformer.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.

We offer amorphous alloy transformer.Its core is amorphous alloy. The amorphous alloy is with relatively high magnet induction intensity, low coercive force, low loss, low stimulated magnetic current, and stability with temperature changes. Amorphous alloy transformer, comparing to the silicon steel S9 series transformers, the empty loading loss decreases 78-80%, empty loading current decreases 50%. Its energy saving effect is very visible, it is a energy saving, environmental protection and high efficient transformer. Main functions and characters: Core is with three phases, four frames, and 5 columns.Use Dyn11 to connect other parts, reduce the influences by network wave, improve the power supply.Oil box is sealed, free from maintenance. Box is sealed, free from maintenance.Empty loading loss is only 20% of S9 type transformers, empty loading current is only 50% of S9 transformer.

We offer combination transformer, (also called american box transformer) combines the body of transformer, switch, and fuse, and other accessories. There are two high voltage load switches; terminal and ring which could apply for different distribution network systems. It is compact, and small, cheap, quick to install. It could be used outdoors as well as indoors, for example; residence, airport, apartment, commercial center, mines, hospital and school etc. It could go into the charge center, improve the power supply. It could also satisfy the requirement as the calculation of consummation, reimbursement, low voltage division. It is easy to operate.Main functions and characters: all insulated structure and interlocking devices, safeall sealed structure, free from oil quality degeneration, prolong the life of transformer.charging switches are interacted in three phased together which reduces the resonance of iron and magnet;double fuse protection, to assure the system simple, convenient, cheap and reliable;silicon steel core, amorphous alloy core, coiled core etc; low loss, low noise, and no temperature raising on box surface;input wire of high voltage is with elbow form connection. Could operation 200a charging current.In emergency, it could operate the charging switch. It could be insulated from switch.small size, only 1/3 of european style box.

We offer 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.

We offer dry transformer. Features: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

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 structureNew parts and new fixing parts

We offer oil immersed transformer.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.
