Toroidal Cored Hermetically Sealed Transformer
Features:1) S11-M.R toroidal transformer is built around a ring-shaped core,which is made from a long strip of silicon steel wound into a coil. Thisconstruction ensures that all the grain boundaries are pointing in theoptimum direction, making the transformer more efficient by reducingthe core`s reluctance, and eliminates the air gaps inherent in theconstruction of an EI core (the typical laminated core is made fromE-shaped and I-shaped pieces)2) S11-M.R toroidal transformer is more efficient than the cheaperlaminated EI transformer. Other advantages, compared to EItransformer, include smaller size, lower weight, less mechanicalhum (only 40 - 50 dB, making them more applicable to indoor use),lower exterior magnetic field, low no-load losses, and single-boltmounting3) S11-M.R toroidal transformer is energy saving and maintenance free.Compared to hermetically sealed transformer with EI core, S11-M.R isusing the same gaskets and hermetically sealed oil tank, whichcompletely isolates the oil inside the tank from the atmosphere,prevents the ingress of air and moisture, slows down the insulatingoil or paper`s aging, and greatly extends the reliability and servicelife of the transformer.4) Compared the main performance parameters with S9-M seriestransformer, S11-M.R has realized four improvements: an averageno-load current reduced by 60% - 80%, no-load loss reduced by20% - 35%, full weight reduced by 8% - 10%, and noise level ofonly 40 - 50 dBSpecifications:1) Standard: GB1094.1-5 GB/T64512) Capacity range: 30 - 800kVA3) Frequency: 50Hz4) Phase: 3-phase5) Tap changing method: off circuit or on load6) Tapping range: ±5% or ±2 x 2.5%7) Connection symbol: Yyn0 or Dyn118) Impedance voltage: 4% or 4.5%Normal service conditions:1) Altitude: ≤1, 000m2) Highest ambient temperature: 40°C3) Highest annual average temperature: 20°C4) Highest daily average temperature: 30°C5) Lowest temperature: -25°C6) Indoor and outdoor7) We can also provide transformers operated in special conditionsaccording to users` requirements
