Feature:
1, Enamelled copper wire is used for high voltage winding and copper foil is used for low voltage winding. The high voltage
windings are filled with glass fiber felt, poured in vacuum with imported epoxy resin without filler, and formed after
curingSolid whole, high mechanical strength, less partial discharge, high reliability.
2,Flame retardant, explosion-proof, no pollution, environmental protection, can be installed in the load center.
3, The coil is not moisture absorption, iron core, clamping parts after special processing can run in 100% relative humidity
and other harsh environment, intermittent operation without moisture treatment.
4, Short circuit resistance, high level of lightning impact, strong overload capacity.
5, Coil inside and outside resin insulation layer is thin, good heat dissipation performance. The cooling method generally
adopts natural air cooling (AN). Air cooling system (AF) is available for transformers of any protection class.
6, Iow loss, high power saving effect, economical operation, maintenance-free.
7, Small size, light weight, small footprint and convenient installation.
8, As a new generation of dry transformer products, SC(B) type dry transformer is suitable for the following places of power
supply; High-rise buildings, theatres, hospitals, industrial and mining enterprises, offshore oil drilling platforms, ships,
subways, stations, airports, power plants, residential communities and high-rise buildings, etc.
