Features & Advantages


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity. 45° mitring and 5-steps overlapping structure is adopted for the core design, thus to greatly reduce no-load loss and no-load current.


To precisely calculate resonance frequency and intensity and avoid cavity resonance generated by the core structure during operation, simulation analysis is carried out for core mould design. Flexible connections are made between core and coils, core and bogie. With these measures adopted, the noise level is reduced by 10~15dB compared with the international standard.

HV winding

HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted with epoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professional imported equipment. Therefore, product's partial discharge is especially low, for example, transformer of 10kV-level has a partial discharge less than 5 pC.


During the HV winding design, rational structure is adopted to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out with special auxiliary software, product's anti-lightning impulse capacity is greatly improved.

LV winding

LVwinding (with the rated power equal to or higher than 400kVA) is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-short circuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface, transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.

Final Assembly

 For series reactor without accessories dismantled during the transportation, it can be put
into various tests immediately after the equipment arrives at customer site. Otherwise,
please mount the accessories such as the oil-reservoir.
While mounting the mercury thermometer or signal thermometer, please fill series
reactor oil into the thermometer pocket.
 While mounting the dehydrating breather, please fill series reactor oil at the bottom of
the breather (for hanging-type dehydrating breather) and check the sealing rubber plate
at the top and bottom before the series reactor is put into service.
 Assemble other accessories and components.
Open the radiator and oil-reservoir’s butterfly valves and fill in with qualified series
reactor oil until normal oil-level is reached (the actual oil-level is depending on the
environment temperature). When filling oil into the reservoir, please open all air release
plugs and seal it by plugging in while oil comes out.
