Overviews
SG(H)b10-100~2500/10 series three phase non-encapsulated
impregnated dry type transformer of my corporation research and
development. Through strict selection, optimization design,
scientific and rational process, rigorous and complete test
facility, it has successfully passed the National Transformer
Quality Supervision and Inspection Center (CTQC) certification.
This series of products use DuPont Company’s NOMEX paper as
insulation material, and having used at present advanced VIP’s
vacuum impregnation technology, reasonable structure and neat
appearance.
This series of products have excellent resistance to waiting,
moisture, salt spray and dust. It operates safe and reliable at
high temperature, small part discharge, low noise, high cooling
efficiency and strong overload capacity. It is a new generation of
green environmental protection dry type transformer. It is most
suitable for the load center which required high fireproof safety
and environmental protection, such as airport, subway, power
plants, metallurgy, hospital, high-level, shopping center,
residents concentration areas, petrochemical, nuclear power,
nuclear submarines and other important places. It’s the ideal power
supply and distribution equipment.
Features
a, Green environmental protection
The whole machine uses high quality and reliable H grade insulation
materials, doesn’t break down and without any harmful gas emissions
at high temperatures;
The coil uses non-enveloped (open) structure, at the end of its
life, copper etc. are easy to recycle and will not pollute the
environment.
b, Reliable insulation system
Choose the United States DuPont NOMEX Paper and Wujiang Taihu ET-90
series H grade modified heat-resisting unsaturated polyester resins
as the fundamental insulation system, 180℃～220℃ insulation system
which passes optimization design can operate safely, stably and
reliably at the high temperature.
c, Advanced manufacturability
Coil whole uses VPI vacuum pressure impregnation and high
temperature curing drying process, so the paint membrance is
bright, even, strong adhesive force, not cracked, small part
discharge≤5pc, low noise.
d, Strong overload capacity
Coil insulation materials use H grade NOMEX paper etc. insulation
materials which test the attestation by UL, non-enveloped
structure, and have high cooling efficiency, Uniform temperature
rise, strong overload ability.
e, Anti-short circuit ability
High and low voltage coil whole conducts vacuum pressure
impregnation process, coil ends use the disc spring and silicone
rubber double preloading device to enhance the mechanical strength
of the coil and the product and improve the anti-short circuit
ability.
f, Excellent endure waiting capability
Product overall coverage H grade insulation paint twice, with
strong painting film adhering capacity and mechanical strength;
painting film is not cracked, with good insulation performance. It
has excellent resistance to moisture, salt spray and dust, is
suitable in the heavily degree polluted environment.
