This manual is to support the installation and operation of oil-immersed series reactor which
is rated 6000kvar or below-6000kvar and 35kV or below 35kV.


Product Features

Being serially connected with the capacitor groups and installed on the busbar, the series
reactor is the reactive compensation equipment of the whole power system. Its main functions are:
1) to reduce the switching-on inrush-current and inrush-current frequency of the capacitor group;
2) to reduce the harmonic wave voltage on the busbar and improve power supply quality;
3) to limit the higher harmonic current to avoid flowing into the capacitor group and to protect the
4) to reduce the over-voltage amplitude during the switching-off period. The product conforms
to such standards as GB10229-1998 reactor, IEC60076-6 Reactor, JB5346-1998 Series

The product features nice appearance, high mechanical strength, small size, low-loss,
high-reliability and etc.. It could be widely used in power transformation and transmission system,
electric railway, mining industry and etc.


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.


Executed standards

IEC60076-11, DIN42523




The series reactor is delivered to customer site mainly through road or railway
transportation. During these types of transportation, the series reactor is transported with
oil filled in the tank. All the dismantled attachments and other technical documents for
customers are put into the cases or boxes and transported to customer together with the
series reactor.


When lifting the series reactor, please use the four lifting lugs at the tanks. These lugs
are designed to hold the weight of the whole series reactor. DO NOT use the lifting rings
on the tank cover, which are used to lift the active part of the series reactor. However,
for hermetically sealed series reactor, the lifting rings on the cover could be used for
lifting the series reactor. During lifting operation, the included angle of the steel rope at
the hook should not be larger than 30°.


During series reactor transportation, the gradient of the series reactor should not be
larger than 15°.
