Minera MP oil-immersed medium voltage power   transformer is dedicated to all applications up to   80 MVA and is designed to meet your needs.   Our broad range for Minera MP transformers includes: • Three phase units (single phase available on request) • Ratings up to 80 MVA, 50 or 60 Hz • Voltage insulation level up to 170 kV • Breathing or sealed type • A wide range of accessories • High capacity cooling options such as ONAN, ONAF, OFAF, OFWF or others upon request • Standard or low noise levels • Off-circuit tap changer (OCTC) or on load tap changer (OLTC) High quality level for more reliability Customer benefits Minera MP  oil immersed  medium power transformer The right tune for your network  Minera MP oil-immersed transformers are also available upon request for special applications including rectifier,  hazardous area transformers, reactors (shunt and series), auto-transformers, step-up transformers, Solar power  plant , Wind  Mill Application etc. Minera MP oil-immersed transformers meet the requirements of international standards such as ANSI, IEEE, IEC   as well as other international/national standards. Our company follows a policy   of continuous improvement taking  into account the latest worldwide  developments. This ensures that  our transformers are state-of-the-art  and fully compliant with the modern  world’s highest requirements: fast  delivery time, improved quality and  recycling capacities, reduced size  and, on request, very low noise and  losses values. Surface protection One of our major quality commitment   is to provide high-quality surface   protection. The coating (painting) type is  chosen in accordance with the envi- ronmental conditions considering the  degree of pollution, humidity, etc. Zinc  Spray / Hot dip galvanized Tank, HV/ LV covers and conservator can also be  provided. Magnetic core The transformer’s magnetic core is  manufactured from a high grade,   cold-rolled, grain-oriented silicon steel.  The lamination stacking is step lap type.  The magnetic core is generally a multi- layer circular cross section and the slit- ting and cutting of the magnetic core is  made by automated machines. In order  to reduce transformer sound level to a  minimum, the magnetic core and   its framework are carefully sized to   minimize the vibrations and, in   particular, magnetostriction effects,  which constitute the main sources of  sound in medium power transformers.  Moreover, in order to reduce the   no-load losses and / or the no-load   transformer current, the quality of the  magnetic steel and the induction,   together with the design of the magnetic  core, are carefully chosen to meet the   requirements. Low voltage windings The low voltage winding material is   copper or Aluminium according to   the rated power. The shape of the   conductor is rectangular or foil type.   To obtain a controlled temperature  gradient, cooling ducts are added in  the coil. The low voltage winding is built  around the magnetic core. An insulating  barrier is wound or installed around the  low voltage coil in order to provide an  electrical separation between LV and  HV coils. High voltage winding The high voltage winding material   is copper or Aluminium according   to the rated power. To obtain a  controlled temperature gradient, the  cooling ducts are added in the coil.  High voltage coils are in long layers   or disc type. Due to recent   developments in the winding   process, interlayer insulation and  wire insulation have allowed the   automation of the winding process.  Tank construction The main tank construction type is  panel radiator type. The corrugated  wall tank is also available in some  ranges. Radiators are welded or  removable. Tank welding is done  by qualified welders. To validate the  oil-tightness after complete assembly,  the tank is leak tested under gas or  liquid overpressure. Oil-immersed medium power transformers With oil conservator or sealed Manufacturing standards IEC, ANSI, BS, AS, GOST, IEEE, IS, BS, etc. Rated power 4 MVA - 80 MVA Voltage level Up to 170 kV Phases One or three phase unit Voltage regulation With off-circuit tap changer or on-load tap changer Short circuit impedance On request as per customer requirement Rated frequency 50 Hz or 60 Hz Vector groups Dy, Yy, Yd as standard, others on request Material thermal class insulation According to IEC 60085 class A, and as per customer requirement Temperature rise Mean winding temperature rise: 65 KTop oil temperature rise: 60 KWith ambient temperature in accordance with IEC 60076-1The temperature of the oil cooling air should not exceed:• 20°C yearly average • 30°C monthly average during the hottest month • 40°C at any time For others ambient temperatures, winding and oil temperature rise can be adapted   Type of cooling ONAN (Oil Natural Air Natural)(ONAF, OFAF, ODAF, OFWF or ODWF on request) Dielectric liquid Mineral oil according to IEC or ANSI standard(silicon, synthetic ester or vegetal oil on request). Short circuit withstand ability  The transformers are designed to withstand the thermal and  dynamic effects resulting of a secondary short-circuit in accordance with IEC 60076-5. Sound level The measurement (A-weighted sound pressure LpA) and the  calculation of sound level (A-weighted sound pressure LwA) are done in accordance  with IEC 60076-10. The sound level requirements are in accordance with national  standards. Installations  Indoor or outdoor HV & LV terminals HV terminals: plug-in or porcelain bushingsLV terminals: busbars or porcelain bushingsOn request: cable boxes according to client / manufacturer standard or norm  (i.e BS) requirements Accesories • Standard: lifting lugs, earthing terminal, name and rating plate, oil filling plug, tap changer, bidirectional rollers if applicable. • Standard for sealed transformers: filling pipe or gas filling valve, oil drain valve,  oil thermometer, oil level indicator. • Standard for transformers with conservator: oil level indicator,  Buchholz relay,  oil thermometer, dehydrating breather, terminal box, oil filling & draining valves, filtering valves. On request: pad lock / locking device for HV plug-in bushings,  pressure relief device, pressure relay with contact, explosion vent, winding thermometer, sudden pressure relay, pressure monitor, rubber bag (only for conservator type),   Gas analyzing purpose systems (such as Hydran), Seal-in Relay, Current Transformers  for protection and measuring, Automatic Voltage Regulator Panel for OLTC, etc. Tappings The tap changers allow voltage   adjustment for a variation of the   supply network voltages on the   primary side of the transformer or   for increasing or decreasing the   secondary voltage. Tappings are   provided on the primary winding   connected to an off-circuit or on-load  tap changer. The operating handle   for hand operated tap changer is  mounted outside. In general, tapping  range for off-load tap changer is 3,  5 or 7 position and for on-load tap  changer it is from 7 to 27 positions.  We provide tap position & range as  per customer requirements.
