1. The well-designedcoil structure and vacuum impregnation
treatment process makes SG (B) 10transformer free of partial
discharge and free of fracturing or insulationlevel decline during
the whole shelf life.
2. Continuouswinding, low-voltage foil burning, overall vacuum
impregnation and curingprocess, as well as support of high-strength
ceramics are adopted for highvoltage, which has good bearing
capacity for sudden short-circuit current.
3. Nonflammable,flame retarded, nontoxic, self-extinguishing,
4. SG (B) 10transformer almost produces zero smoke under high
temperature and flamingconditions.
5. The transformeris of Class H (180℃) insulation.
6. The insulationlayer is very thin and uniform. The short-term
overload capacity is strong,forced cooling is unnecessary, 120% of
long-term overload, and 140% ofoverload for 3 hours are possible.
Since such insulating material is ofanti-aging and flexible, full
load immediately is possible under thecondition of ±50℃.
It adopts non-encapsulatedcoil three-phase dry-type power
transformer produced by NOMEX insulationsystem approved by United
States UL, which characterized by safety,reliability, energy
saving, fire protection, anti-explosion, simplemaintenance and so
on. It boasts advances design, reasonable structure,good-looking
appearance and main performance indexes which are superior
tonational standard, such as partial discharge level, no-load loss,
load loss,noise and adaption to high-humidity atmosphere.
It can be installed in dirtywet environment near lake, sea, river
and in area with high fire protectionrequirements and large load,
suitable for high-rise building, airport,station, wharf, metro,
hospital, power plant, metallurgical industry,shopping center,
residential concentration area and petroleum chemicalindustry,
nuclear power plant, nuclear submarine and other places.
