2. Product Features
the big capacity dry transformer with stainless steel enclosure has
longer service life, better energy saving, lower noise, lower
temperature rise, less ultraharmonics, smaller ripple factor,
strong impulse withstand capability and desirable flame retardant
HV winding is manufactured with high quality copper wire,
reinforced with glass fiber and being cast with epoxy resin at
vacuum state with pressure. The cast resin will completely be
soaked into coils, so the partial discharge of 10kV product is low,
and will not exceed 5pC. HV windings adopt excellent structure, and
with lighting impulse simulation calculating and analyzing, the
ability of resisting lighting impulse is improved.
LV winding is manufactured in high quality foil conductor, so the
additional loss is low and the performance of dynamic thermal
stability is excellent. Air drains of heat dispersion are
ingeniously used in the winding, and the surface of heat dispersion
is increased, so the temperature is reduced and the ability of
over-load is improved.
Attractive and durable protective enclosures are available to
provide additional protection for transformer, and the protection
level is IP20, or higher, depending upon your needs.
