S11-M.RL 3 Phase Distribution Transformer with three-dimensional

 S11-M.RL,Three Phase Distribution Transformer with three-dimensional wound core is a new type hi-tech and high energy-saving product. Compared with series S9, 80% of no-load current and 30-40% of no-load loss can be decreased, 8-13dB in noise level can be reduced. It is applicable for distribution, power supply and lighting in industrial, agricultural, mineral, petrochemical fields.  

Normal service condition of Three Phase Distribution Transformer 
    Elevation height less than 1000m
    Environmental temperature
    Max. temperature +40ºC
    Max. daily average temperature: +30ºC
    Max. annual average temperature +20ºC
    Min. temperature -30ºC
    Operation environment   outdoor
    Symmetry of multi-phase power source
    Three-phase power sources shall be almost symmetrical.

Feature :

      1.Three-dimensional wound core consists of three core limbs whose cross-section is close to circle. Magnetic circuit in three phase is totally symmetrical and identical, which shortens the yokes but makes factor of core limb bigger.
      2.After annealing, internal stress can be removed thoroughly for three-dimensional wound core. There is no higher magnetic reluctance everywhere in its circuit, so no-load loss and energizing current can be decreased greatly. The test shows that more than 80% of no-load current and 30-40% of no-load loss can be decreased.
      3. Only fewer joint caused by continuous wound core, there should no noise occurred due to the blocking inside the magnetic circuit of stacking core. In such way, 8-13dB in noise level can be reduced, which is almost in the state of noise silence.
      4. Triangle tank is used for such transformer so it is smaller than the normal one. In a word, it is impact, small size with artistic appearance.
