3.Type and Signification

voltage grade/ rated capacity/ capability level code/ foil round winding/ Resin casting type/3-phase transformer

4. Function

4.1 Good spread hot, long service life, strong load, which can keep on circulating with on-load in the environment of more than 120% load and no winding.

4.2 High safety and protecting fire capacity, no smoking discharge in the high temperature of 800c burning.

4.3 Strong withstanding hot capacity

4.4 Completely waterproof and damp-proof

4.5 Low-loss, obviously saving energy; compared to the SC9 series dry transformer, the no-load loss average decreased 10% ,the on-load loss decreased 5%

4.6 The insulation material and copper winding after use-life can be reused with no pollution

5.Structure

5.1 Special insulation structure of H grade high insulation, high frequent porcelain and ceramics mat piece. It isn’t curved forever.

5.2 HV&LV coil packaged by NOMEX copper line and entry copper foil.
