Introduction to Products
Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper. It is artistic in appearance and safe in running and is widely used in transmission and distribution of industrial and agriculturalist.
Main Function And Features
It adopts radiator oil tank of corrugated sheet type or expansion type. As it doesnâ??t need oil conservator, the height of transformer is reduced , and as the transformer oil doesnâ??t contact with air , the oil ageing is retarded, thus prolonging the service life of transformer. The no-load loss of Model S10-M is 20% lower than that of Model S9-M , and S11-M is 30% lower than S9-M. the transformers are high in reliability , advanced in performance and rational in economical indexes . The oil tank is diversified in types and looks artistic and elegant.

INTRODUCTIONS
I- GENERAL CHARACTERISTICS

Transformers immersed in insulating fluid with natural self cooling (ONAN), three-phase, 10 - 20 MVA.for indoor or outdoor use, 50/60 Hz, hermetically sealed.

II- MANUFACTURING STANDARD
The transformers described in this catalogue are designedand tested in accordance to IEC/BSEN 60076

III- RATINGS
30,50, 80,100,125,160, 200,250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500kVA.

IV- HIGH VOLTAGE
This material is designed for voltages of â?¤ 36 kV. Specific figures are not given for this parameter because of the wide variety of voltagesused. Transformers can be supplied on demand to run at two different primary voltages, the shift between these input voltages has two basic alternatives:
with a primary tap changer which can be switched with no load and no applied voltage
or by changing terminals under the cover.

V- LOW VOLTAGE
The secondary voltage under no load is allocated at 400V, 415V, 433V, though other voltages can be supplied on demand. When usage requires two voltages, transformers with two simultaneous voltages can be supplied. In this case the no-load voltages are set to 400V(230V),415V(240V),433V(230V).

VI- VECTOR GROUP REFERENCE
The connections normally used are as follows:
For rated power levels of 160 kVA or less: Yyn0
For rated power levels over 160 kVA: Dyn11.

ACCESSORIES

I- BASIC EQUIPMENTS
All transformers are supplied with:
3 high voltage bushings
4 or 7 low voltage bushings
5-position tap changer on cover, workable with transformer off load
2 lifting & tank removal eye-bolts
Filling hole with M-40 x 1.5 outside thread and threaded cover
Drainage & sampling plug at bottom of tank
Two-way, standard rail gauge welded at the bottom of tank
2 earthing connections at bottom with M-10 screws

II- OPTIONAL ACCESSORIES
Thermometer
Tap changer
HV plug-in bushing
Thermostat
Protection & control block for the following
