The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, enable the effectiveness of reducing no-load loss and no-load current.
HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.
LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.

110kV class on-load tap-changing power transformer
110kV class off-load tap-changing power transformer
According to the inspection items of the transformer running rules, the degree of insulation damped should be identification, and base on the result, decide whether the transformer should be dry-processing before running.
If transformers have no abnormal phenomena during transportation, need not to hang cover to check body before running. If necessary, the inspection must be in accordance with the transformer running rules. While checking, in order to hang the upper tank, disassemble the connection components between the upper tank and the body according to the transformer assembly drawing. While disassembling the on-load tap changer, it must be done strictly according to the switch manual, and need to use a special tool to hang out the core of the change switch.
Storage for more than 3 months
Install oil conservator and necessary pipeline, and oil the tank according to the oiling instruction. (To prevent water from entering the coil)
Install hygroscopic utensil.
