01

H-Grade Insulation

SG10 Series power transformer use great material and new technology to achieve H-grade insulation, it is reliably used in ambient temperature up to 180℃and the main part of the transformer can sustain up to 220℃.
02

Safety

SG10 series power transformer using insulated materials which is flame retardant and moisture-proof, the combustible material is only 10% of the epoxy resin transformer. There’s no poisonous fumes during long time burning at 800℃. SG10 and SG11 series power transformer is mainly applied to high safety requirements, moist and poorly ventilated installation site, such as power station, railway, shipbuilding, chemical industry, metallurgic industry.
03

Reliable

SG10 series power transformer using special coil design and technology to achieve moisture-proof, mould proof and fame proof. It can sustain high thermal shock without partial discharge.
04

Strong over-load ability

SG10 series power transformer can sustain 120% rated capacity. It can longtime running under IP23 without force air cooling.
