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



Maintenance and Repair

To ensure the reliable operation of the equipment, please carry out regular inspection and
maintenance for the equipment.


Generally, if the equipment is installed in dry and clean environment, please inspect the
equipment each year. If the equipment is installed in a high-pollution environment, such
as environment full of dust or chemical fogs, please inspect the equipment each 3 to 6


During inspection, if too much dust is found accumulated on the equipment, please
clean these dust in time, thus to ensure good ventilation and avoid voltage break-through.
Special attentions should be paid to the inspection of the transformer’s insulator,
insulation padding block, tope and bottom. Use compressed dry air to blow out all dust
within the air passage.


Check the fastening components to ensure there are no loosing parts. Check the
components and sub-assembly to ensure there is no rust and corrosion. Check whether
there is creepage or carbonization trace on the insulation surface. If necessary, proper
measures must be adopted.
