Product Description

Product Features

Our SC(B) series epoxy resin cast dry-type transformer is cast under vacuum with thin insulating bands automatically. The core is made of high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials, scientific management, and perfect inspection means, our transformer has many advantages.
    · Security, flame retardent fire prevention, no pollution, and also can directly installed in load center.
    · Low loss, low partial discharge, small noise,strong cooling ability, can operate at 150% rated load under forced air cooling conditions.
    · Moistureproof performance is good, can operate normally under humidity, after the normal operation without predrying can be put into operation.
    · Maintenance free, easy installation, low comprehensive operation cost.
    · Equipped with perfect temperature protection control system for transformer provides a reliable guarantee for safe operation.
    · High reliability,according to the product which has already been put into operation, the operation reliability of products has reached the               international advanced level.
    · It highly withstands short-circuit and lightning impact.Small in volume, light in weight, safe in running and free of maintenance. As per users' requirements the transformer may be provided with casing and blower fan.

 

Structure Characteristics

Box coil:
The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.

Temperature control device:
The transformer adopts the BWDK series signal thermometer. The temperature measuring element is embedded in the upper half of the low-voltage coil, which can automatically detect and display the respective working temperature of the phase coil, and has the function of over temperature alarm and trip.

Normal operation condition 
    · Ambient temperature: Maximum +40ºC
                                         Minimum -25ºC
    · Relative humidity: At 25ºC, not higher than 95% for daily average humidity and not higher than 90% for monthly average ambient temperature.
    · Altitude: less than 1000 meters.
    · Seismic level: less than 3m/s² at horizontal direction and less than 1.5m/s² at vertical direction.
    · Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: if the application environment is different from the above standard service conditions, please contact us for customized designs.)
