Application Of Products
     Our SC(B) series epoxy resin cast dry 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 products have the following features:
             The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble and has low local discharge, high reliability, and long service life.
              The high-and  low-voltage systems are cast under vacuum, thus the coil will not absorb moisture; the clamps of core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments.
             Flame retardancy , explosion-proof and no environmental contamination. The insulating materials in the coil such as glass fiber are self-extinguishing and they will not cause fire by the arc resulted from short-circuit . The resin will not generate toxic or harmful gas under high temperature.
             Gas duct is embedded inside it to enhance the radiation power and over-load capacity.
              Low loss and low noise. The core is lapped with 45 full-miter  and the step-type lamination effectively improves distribution of magnetic flux at core corners, and greatly reduces the no-load loss and the nose 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

Test lab And Inspection
IEEE IEC ISO CE 20 Years Professional 1250kVA 20kv Dry Type Transformer


Testing are conducted for every transformer before delivery.Tests are classified to be routine tests and type test.
A - Routine tests: According to IEC 60076 standard , the following tests must be carried out for all units of the transformers
- Measurement of winding resistance .
- Measurement of voltage ratio and check of phase displacement.
- Measurement of short circuit impedance and load losses.
-Measurement of no-load losses and current .
-Dielectric routine tests including the separate source AC voltage withstanding test and short duration induced over voltage withstanding test ( ACSD ) .

B - Type tests :
The following tests shall be carried out
- Temperature rise test
- Lightning impulse test

C - Special tests :
- Determination of noise level according to IEC 60551 .
- Oil leakage test
- Overload test at 150 % rated current for one hour after temperature rise test ( top oil temperature rise and winding temperature rise must be measured and recorded in     the report test also hot spot temperature rise must be calculated and recorded on the report test ) .
- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
