Three-phase Scb12-2500kva dry-type transformer 10 / 0.4 kv power
transformer, all copper
1. Product description:
The cast coil transformer is a low-noise, low-loss, cast resin
dry-type transformer.
The high-voltage (HV) winding with copper conductors and the
low-voltage (LV) winding with either copper conductors or copper
sheet are wound and reinforced by glass-fiber and then cast with
resin under vacuum.
2. Product advantages:
a. Safe, hardly inflammable, no pollution.
b. Lowloss.low noise.high reliablity
c. Highly moisture-proof ability.
d. Good fire prevention and isolation performance.
e. Maintenance free.
f. High heat resistance.Moisture resistance.

3.Structural Characteristics:
Cast-foil Coil: Adopting the entire section of copper foil, together with the
F-class turn insulation, low voltage winding is Coil:wound by the
special low-voltage foil winding machine. The foil coil resolves
such understanding problems as large short-circuit stress, uneven
ampere turn, poor heat dissipation, existing the winding spiral
angle as well as unsteady manual welding quality due to low voltage
and large current coil winding products. At the same time, the
winding end in our company is treated with resin potting,
solidification to make shape, moisture-proof and anti-fouling, the
lead copper platoon is automatically welded by argon arc welding.
Temperature Control Device: the transformer adopts BWDK series of signal thermometer. The
temperature components, are embedded in the upper half of the
low-voltage coil, can automatically detect and dynamically display
the work humidity of phase coils and also have the functions of
over-temperature alarm and trip.
Product usage
SC (B) 10 epoxy resin cast dry-type transformer is manufactured
according to standard of Dry-type Power Transformer, characterized
with low performance loss, good energy saving effect, economic
operation and no maintenance. In addition to high process structure
metal, short-circuit resistance and lightning impulse level, it is
still characterized with flame retardant, dampproof, dust-proof and
low noise, which can be connected to load center. It is widely used
in high-rise buildings, airport, station, wharf, power plant,
transformer substation, etc., especially applicable to be used in
places with high fire protection requirements for flammable and
combustible materials.
Standard transformer produced by the Company has no case, with the
protection level of IP00, and case with the protection level of
IP20 and IP23 can be provided as required by clients. Housing is
made of such materials as common steel plate, corrosion resistant
plate and aluminum alloy and then treated with acid pickling,
phosphorization and plastics spraying according to the requirements
of clients. Temperature control indicator and load recorder are
installed on the low-tension side of the housing, convenient for
observation and safe and reliable.
