1/2/3mva 3 Phase Dry Type Cast Resin Transformer Three Phase Two Winding Transformer

Product Description

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.
