Categories:

 

Winding Number: 60 kV class 3-phase two-winding power transformer

 

Tap-changing:60kV class on-load tap-changing power transformer

                       600kV class off-load tap-changing power transformer

 

 

 

Oil for transformer and tap-changer Type and quality

 

 

Only new naphthenic-based oils, which must be certified as such prior to filling, shall be used.

 

Where the first filling of virgin oil is to be supplied by the contractor, the oil shall at least be as specified NRS 079, without any additive. The colour coding of the drums containing the oil shall comply with the requirements of NRS 079.

 

Under no circumstances shall poor quality oil be filled into the transformer and only thereafter be brought up to specification by circulation within the transformer.

 

Dielectric strength

 

The power frequency dielectric breakdown strength of the oil in any part of the transformer and on- load tap-changer shall meet the transformer manufacturer's requirement. But shall, in any case, not be less than 70 kV/2,5 mm for virgin oil prior to filling and not be less than 60 kV/2,5 mm at time of take over.

 

Dielectric strength shall be determined in accordance with the method prescribed in IEC 60156.

 

 

Executed Standards:
IEC60076

 


Features & Advantages

 

HV winding:


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.

LVwinding:


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.

 


Core: high quality cold rolled grain-oriented silicon steel
 


Insulation Structure:HV and LV windings are arranged in concentric way.



Tank:  The tank is jointed with high-quality steel. 

Accessories: The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories.
